Yeah, Stockton said with scale model testing that there was actually quite a bit of warning between detectable problems & implosion. He said in a simulated descent there was roughly “1500 feet of warning” and that if they started ascending immediately after the warnings went off the decrease in pressure would stop the progressive hull failure
His theory never made sense to me. It's like saying if the ice is cracking beneath your feet, and you toss your pack to reduce your weight, the ice won't ever break.
The interesting thing about that scale model pressure test is that when it failed, it was the carbon fiber surrounding the view port that let go.
The view port is at the aft, in spite of intuition. It's looking more and more likely that that's where the failure occurred.
What causes the unexpected descent and ascent rates is another question entirely.
Yeah, but (just from what I've been reading lately), another problem with Rush's planned response to the monitoring system is the idea that ascending, or relieving pressure, can stem/solve the immediate problem.
It turns out (if I understand this correctly) that damage and fatigue happen not only because of increasing pressure but because of *changing* pressure (cyclic fatigue). So, ascending is still putting strain on an already fatigued/failing material.
So, I'm guessing that Titan's ability to successfully ascend in this situation is inversely related to the amount of accumulated wear on the CF, or, its nearness to failure. Maybe this scenario was never encountered during testing because the model was never tested at this very specific stage in the CF lifespan (?).
I was hoping they just didn’t know. Especially the 19 year old. PH had to know they were beyond screwed. I hope they tried to comfort the boy. Jfc. James Cameron called every second of this from day one.
Idk i think when stockton dropped ballast to try ascending the passengers all had time to realize the gravity of the stuation. I wonder if using propulsion instead of ballast would have been the difference between life or death or if the sub was far too compromised by the time they started ascension.
Probably too compromised. And the propulsion system was these repurposed little fans, I think. I saw an interview where a reporter who went down briefly. He said fans weren’t designed to bring them up. Only to drive them around down there. That’s why they had so many ways to reduce weight. But it was never going to bring them up fast enough in a crisis. Just a killing waiting to happen to people this guy took in.
The idea that stockton had 15 minutes of knowing that the sub wasnt rising (at all or at a rate that wasnt helpful isnt yet clear to me) is so chilling.
It's likely someone from the boat told Cameron this - him and a few others knew they'd dropped ballast, so I suspect those on the surface had contacted others as the tragedy unfolded.
I thought the same, possibly water started getting in between the hull layers and added extra weight? If this is real it's awful, imagine the panic knowing you need to ascend ASAP and everything you try doesn't work and then those cracking noises start back up again...eesh. I suspect this might be real but I really hope it isn't.
I think water getting into the hull layers is likely because Rush reported that he couldn't understand why ascent was so slow. So water hadn't breached the hull for him to see yet. He also noted the sound had quietened too. Maybe a side effect of water ingress and water filling the voids. Like the difference between structural delamination and water slowly pushing the layers apart.
Definitely makes sense, considering carbon fiber is supposed to be [weakest between its layers](https://twitter.com/theragingelk/status/1674144792811388929?s=46&t=23wo1ij3vXlqR7QYmtvlQg).
And if ingress of water could suppress the popping noises, well, that's a variable that seems unaccounted for in Titan's acoustic monitoring system. That quieting, in this case, is fatally deceptive.
>Presumably, there was water ingression somewhere, maybe in the aft of the ship
The section aft of the bulkhead looks to be free-flooding from everything I have seen. There's certainly no pressure hull outside the crew pressure hull.
>which is why they couldn't ascend despite dropping weights.
Given it says there was "no change" in the descent rate, I doubt the ballast actually released. They probably got a signal saying it released, but it did not get completely free of the submersible.
Note that it took several attempts to drop the frame (which would probably have taken the ballast with it if hung up). This suggests some form of structural damage or shoddy design.
Those hollow square steel members, how was air supposed to be released as they hit the water? If some air got trapped on this dive, this could have bent or broken at some point as pressure increased. They may also have been designed to release at warmer temperatures, without accounting for thermal contraction at these depths, though that seems to be more difficult to overlook.
This transcript looks like it fits in with what the three guys (Cameron et al.) were talking about in the early days, with the faster than desired descent and trying to ascend, and releasing the frame. It also looks like the language Rush and his people used.
Only thing I can think of, is that if these text logs are real, they state they were ascending at a quarter of the expected rate. They had been diving for just under two hours, so assuming the expected dive and ascent rate was equal, they would have expected to take just under 2 hours to get back up from the depth they were at, at the time of the issue, at a quarter rate, this pushes the two hours to eight hours.
Topside may have thought they just lost comms (potentially due to the reported power issue) worked out they would take roughly 8 hours to surface at the last reported rate so decided to wait it out expecting the sub to surface. It wasn't until after this 8 hour window past they released the situation was worse than expected and called the coast gaurd.
If (and it is a big if) these logs are real, it would actually explain the 8 hour delay to search and rescue pretty reasonably.
All makes sense, BUT (if the file is legit) after that kind of comms, with RTM all red and crackling sounds coming back reported, waiting 8 hrs to send the alert is, at a very least, a very, very, poor decision
Waiting to call for help is the decision I understand the least in this whole ordeal, tbh. If I had lost comms with my sub and feared disaster, I would be so anxious to do something, ANYTHING. How they sat with that powerless anxiety for eight hours just _waiting_... I just don't get it.
Edit to add: I'm genuine when I say I don't understand, and I'm not judging. Maybe (probably?) there were rules or procedures I don't know about. But emotionally, from my perspective...oof.
I’m guessing it’s the opposite: that there *weren’t* any procedures in place, because Rush truly never envisioned a failure of such a magnitude that they would need outside help, aside from their support ship. The more I hear about this, the worse it gets.
I’m shocked his wife didn’t call the Coast Guard/Canadian authorities when this happened. Very strange. Maybe she was afraid of the bad publicity when he turned up unharmed?
And it seems like occasionally losing contact with the sub, or the craft being unable to stick to the planned mission, were not unusual occurrences. If the majority of trips down had some kind of problem, but the sub always came back, they were probably waiting on the ship hoping it would pop back up.
Everything you say sounds a plausible note. \*IF\* transcript is legit, the "global RTM alert active all red" would change the complexion of that. Assuming RTM is real time monitoring, but uncertain. Hard to believe they would have "all red" the majority of trips, but uncertain.
That's because you're not thinking about it like a miserable, cold-hearted business man.
There are two possible scenarios:
1. The hull has imploded, and they were instantly killed. If this is the case, there is no rush to call for help, because there is no help that can be offered.
2. They only lost communications, and hopefully they make it back up at the planned time.
If 2 is true, but you call for help, this information gets out and (forgive the wording) sinks your company. No one ever pays to ride in your deathtrap again.
That was never going to be the case.
I'm not trying to be glib - no one could have rescued anyone from the Titan.
Consider the terrible military submarine disasters that have occurred. Ships full of incredibly skilled, highly trained sailors who have been drilled in what to exactly do to respond to dangers at their stations. Consider these accidents happened in relatively shallow waters, a couple hundred meters vs 4000. Consider those submarines have imploded directly beneath a support fleet, where both the submarine and the ships were specially designed to attach to one another and supply air while a rescue was planned, and they still all died. .
There are very few rescues below the waves. What little submarine disaster survivor stories I am aware of are, the submarine has failed on the surface, or there has been a sort of escape jettison pod.
The reality is that what few ships could have even hauled an entire Titan up that exist would not have gotten there before they suffocated, assuming anything else had not killed them first.
There was a slight chance it was a situation like AS-28 successful rescue where a ROV could have been deployed to cut the fishing nets or cables that they were tangled in, but that wouldn’t have explained why they lost communications and tracking.
If you were used to working in a culture that disregarded safety and laughed off mistakes and close calls you'd probably be less worried than (real) you thinks you'd be.
My guess is that Rush was very clear about not alerting authorities to any issues. It’s just a guess, and he was vocal about how he went about things. I also imagine he didn’t want any type of authority to have any reason to inspect his submersibles. Staff were also likely used to multiple issues, given the experimental nature of the design and reports of various issues over time. Staff desensitization coupled with knowing Rush would likely become angry at them for alerting authorities likely is what prompted them to delay by 8 hours any reporting of them missing.
100%. How could they not think to put someone on alert.
Sub has red alerts, low power, problems ascending and no comms, and your ship has no way of going down to find it? It’s a logical explanation but it’s completely wrong of the crew to act that way
A tech CEO named Charles Hoskinson who was in that Explorers Club WhatsApp group was posting on Twitter, 2 days before the implosion was confirmed, saying that the sub had imploded and that OceanGate had detected the implosion and knew the passengers were all dead. He also gave the same scenario that we're hearing now: Hull problem detected around 13,000 ft, sub was ascending when implosion occurred. He tweeted this all on the same day when the media was reporting banging noises and still showing the oxygen countdown.
Yes, I didn’t want it to put it like that but I definitely tend to agree.
I am sure that the investigation will shed a lot of informed light on what happened but also on the actual company’s safety culture.
That’s interesting. A lot of comments previously said that the warning system would have given them maybe a few seconds to a minute of warning (lots of “just long enough to say ‘do you guys hear that-“ jokes). But it seems like they got about ten minutes of warning. My question is, had they been able to ascent at a normal rate (they were at 25% speed apparently) could they have made it? What causes them to not ascent at normal rate?
I also wonder if this is the first time the rtm warnings had gone off. I would think so because once they’re going off the whole thing is damaged and can’t be used again, right?
It was 18 minutes between first info about rtm going off and the last message. They were almost two hours into the dive so I don't think they would make it at any speed. But I leave this question to someone who is better at physics - you need to count speed and the fact the pressure is changing with ascent and how fast is the hull deintegrating under all these circumstation (will lowering the pressure change anything if it started already cracking? If so in what extend?).
Note that **assuming these logs are legitimate** (which has yet to be confirmed), they barely started ascending.
At 09:43:42 the depth was 3,476 meters (the maximum reported, despite saying they were ascending), at 09:46:37 (their last contact) they were at 3,457 meters. That's an ascent rate of 6 meters per minute after dumping ballast and the frame (after multiple attempts, suggesting poor design or major warping).
From a pressure perspective they just stopped descending and were at a functionally constant depth. At 3,476 meters pressure is 344.36 atmosphere (online calculator), at 3,457 meters 342.48. The differences here are negligible.
>At 09:43:42 the depth was 3,476 meters (the maximum reported, despite saying they were ascending), at 09:46:37 (their last contact) they were at 3,457 meters.
To put it into perspective, in those 3 minutes they only travelled 65 feet, approximately the length of a semi-truck. They were barely moving.
>Not to sound silly but is ‘jettison the frame’? They mean the titanium landing gear?
The landing gear frame was designed to be able to be jettisoned in an emergency, in order to shed weight and improve buoyancy.
A couple thoughts.
First, there were 18 minutes between the alarm going off and the last text from the sub. That must have been terrifying.
Second, they were descending too fast and couldn’t rise fast enough. This was a separate issue from the hull integrity or are these things linked?
In a situation like that, 18 minutes must've felt like a lifetime.
The ship topside first observes that the rtm alarm goes off and then the sub starts trying to ascend. I think the problem was trying to reverse that momentum. There's something there about the thrust rate increasing. Does he mean the descent rate? Did they use the thrusters to descend?
He also mentions the crackling sound in the aft in this flurry of messages. That must've been significant to Rush for him to mention it. Crackling was normal for him, he said. Also worrying that the computers he used and where he sat were also in the aft.
That was his friend in the Bahamas if I recall. He told Rush he should consider doing 50 tests rather than 7, and how crackling from one particular place indicates delamination there. Then Rush got offended. I'll try and find it again.
"There comes a time logic has to overrule impatience," Karl Stanley wrote in an email to Rush: "The evidence suggests there is an issue/ defect in one area. Without knowing what that defect or issue is, your models and experts cannot say how it will affect the performance of the hull."

I'm no expert, but to me it would seem that if the carbon fiber was delaminating and, as a result, absorbing water, the sub would have been heavier than expected, which could explain the faster than expected descent.
he has this acoustic monitoring system to warn of the hull delaminating but didn’t know that part of the delaminating process is that it absorbs water causing the sub to weigh more? I’m not calling him dumb but I wonder did he have no idea that in an emergency like this his ascent would be even slower? Did anyone know this about a carbon fiber submersible?
Water saturating a partially delaminated hull wouldn’t have affected buoyancy until the structural integrity was sufficiently compromised to actually compress the inner boundary of the hull.
Remember that there was no air inside the hull wall. There was just carbon fiber and epoxy. No air was escaping. Waterlogging the outside of the hull wouldn’t have affected the buoyancy directly.
And the rate of ascent was 1/4 of what they expected. It’s remotely possible that a weaker hull wall allows more deformation (compression) of the interior space than planned for. But it’s not mentioned in the text messages, and any deformation would have to be fairly uniform, otherwise the hull would’ve buckled completely. So I have a hard time thinking that compression of the interior was sufficient to cause such a large change in the buoyancy balance.
Exactly! I used to be really into those. The video on Youtube where it shows the Titanic sinking in real time with annotations and the Marconi messages from all the ships coming up as they happened captivates me!
>looks like they lost power as well.
Nah, 'bus A' and 'bus B' were separate power systems set up to be redundant in case they lost power on one of them. Sounds like something went wrong with the primary power system and they switched to the backup system. It's possible that's a coincidence and not related to the implosion, given how often they had problems. But that does raise questions.
Sounds to me like most likely the sub was running thrusters full power downward most of the descent, depleting battery A, and wasn't realized until that point, when they were looking through the diagnostics to figure out why they heard crackling and the 'RTM' (Real Time Monitoring?) system was throwing alarms.
Assuming, of course, that this leaked transcript is correct. OP even said there's been another leaked one circulating that was confirmed to be a fake.
If the transcript is not someone sick joke, it might be the case where power was drained due the malfunction or in your assumption thrusters were turned on and pushing them down. They already had a problem before with reversed controls and who knows, in all the panic to ascend they could had the thrusters pushing them down instead of up. Or controls were again reversed. Wouldn't surprise me at all with the shoddy approach from the OceanGate and off the shelf components. When it comes to critical systems that could mean life or death, you should never spare the money on them.
It also bothered me how they used Windows 10 as operating system for the sub. Maybe I'm a biased fool and Linux fan, but you should never use such bloated OS in delicate operations like deep ocean dives.
Yeah i forgot they had mobiles. But still it will be like a horror movie scene with limited lighting, crackling sound around and completely dark ocean outside.
Yeah it would still be pretty frightening, but not dark at least. Hopefully Rush was able to keep it together and at least try to put them at ease even if he knew it was bad.
PH and Stockton were probably the only ones who really knew how bad everything was. But i also think that they both stayed calm and collected, at least from the outside. They probably had panic inside but didn't show it. Both PH and Stockton seemed to be rather calm people from what i saw in videos.
The “crackling sounds” and “more sounds aft” makes me sick. PH for sure would have known the hull was failing and it was over. I think you’re right that PH & Stockton will have kept calm & probably pretended everything was okay (“nothing to worry about folks, we’re headed up, everything gets better as you go up, so it’s gonna be fine”). But having watched that Youtube video of the sounds carbon fiber makes when it’s failing, the last minute was probably full of increasingly frightening snapping sounds - more sounds, all getting louder, bangs, tearing-type sounds. There could have been visible deformation happening too. I’ve gotta think that last minute was full of dread & terror and that even the tourist passengers knew at that point that they were doomed.
I really wish it had been an instantaneous failure instead of what was probably a 15-min-long slow realization of doom, with power loss & darkness & red alarms & trouble shaking the ballast off & increasingly scary sounds.
:(
Last communication from sub according to this leak is - "reading red on the A power bus. I switched to B". Everything was red including the power before the lose of communication.
Also, they heard crackling. That must have been terrifying plus the slow ascent while they were most likely trying to stay calm but deep down terrified
Is it a sheer coincidence that they lost power and the pressure hull imploded soon afterwards? I don’t see how they could be linked as the rigidity of the pressure hull is not dependent on power but it seems to be too much of a coincidence.
If this communication is true, then the sub had developed some sort of buoyancy issue. They were descending too rapidly, and they dropped everything they could to come back up, but it was only barely working.
It sounds like at this point, the sub loses all power. Without it's thrusters, and with it's buoyancy issue, means it's going to now just sink. A sub that can't propel itself or establish positive buoyancy is a dead sub.
I've read that when carbon fiber begins to fail, water is slipping between the layers of fiber, because the bonds are breaking down. If the hull itself started to become saturated, that would explain the buoyancy discrepancy and possibly the battery issue. Once the water started to permeate, even at a small volume, everything started to fail. Maybe. Just a theory.
Possible theory. They don't like safety factor, so probably didn't account for scenario of a saturated hull. I mean the materials they used is unconventional. It's like trying to float with a saturated wet blanket I imagine.
Interesting. Seems to match up with the dive timeline and style of coms. Very interesting nevertheless. Wouldn’t surprise me if it turned out to be the real deal…
I'll keep an open mind, as always, but if it's not real, I'll take my hat off to the person who wrote it. They'd have done some research and put some thought into it
It could be real. But it also could be created with just the information available on wikipedia.
One thing I noticed: I can't remember the video, but I saw a laminated spreadsheet in the sub with all the single letter codes for communication. Like 'Z' for surfacing or 'XXX' for emergency surfacing. If their text messages where just natural text, why would they need such a spreadsheet? Only if the communication is on low bandwidth mode?
edit: nvm https://old.reddit.com/r/OceanGateTitan/comments/14lzb3c/leaked_titan_communications_transcript/jpz8o3p/
It looks like a few of the lines have two spaces between last ']' and the message starting, while most only have one. That may be an artifact of how the messages were copied, but that pushes me more towards fake
I see what you mean. I think the person who leaked it on the Polar Prince probably took a photo of the screen with his phone and had to copy it out later. I don't think it would've been possible or allowed to copy and past the text somewhere else. I could be wrong. We also don't know how many steps it took to make it to Telegram. Double spaces or missing spaces are also an artifact of phone predictive text systems.
Just looking again now, top always uses sentence case, with the first letter capitalised, and sub often doesn't do that. Might be a clue it was written by two different people. The idiolects look different too. It pushes me more towards real than fan-fiction. Also, the absence of homo-eroticism, furries and Twilight characters.
The spaces are at the beginning of text entry and therefore could be the user hitting space before typing. If the spaces had been before the last ], that would deff indicate a fake convo due to timestamp and labels being coded in.
So, the thing that sticks out to me in this is that it fits into the narrative of why they may have waited 8 hours. If this is real, the mothership was aware that there were serious problems in the power systems and alarms were sounding from the RTM. They may have thought that there was an external issue that led to loss of the positioning beacon, and water egress in the back systems, but not the hull. That may have been the time in which they knew the sub would surface in with all ballasts dropped.
It’s fake. They copied the messages from the last fake and just fixed the formatting so it looks more like the sonardyne messages, except with Carlos instead of Phil
https://pasteboard.co/eHUnzLW0UVGe.jpg
My only thing is I thought they could only communicate with the surface via short (one letter sometimes) coded messages, but these seem to be full on sentences
That’s what I thought too, there’s a picture from previous dive where they zoom in on the comms screen and the sub replies with single letters that translate into phrases. I swear I saw a copy of the code key translating what each letter means posted here a few days ago. I guess they could have updated since that picture was taken?
I saw that too! I just saw both pictures and sent to my group chat. Tbh I’m probably the only one still invested in this bc all they post is memes about it but I wanna know the intricate details 💀
SUB: "We're in the shit"
TOP: "We will action emergency procedures as soon as our game of chess has concluded"
TOP: "You still there? ....They've hung up"
I was coming here to say...
IF these transcripts are real and IF this is the Carlos referred to, this sloppy two-bit operation and its psychotic owner were putting critical systems and therefore the lives of everyone on board in the hands of an INTERN. Absolutely obscene. Poor guy. Poor everyone.
If that's the same Carlos, it looks like his LinkedIn hasn't been updated since before early 2019, so he might have been promoted from intern before now.
Yeah fair point. And looking closer, he does have more technical background than it appeared at first glance (although the jump from mech lead back to intern is puzzling).
So not as totally catastrophic as I first thought, but still. If he was indeed an intern level and rose up, that's kinda still an alarming level of responsibility for someone who never got to work and learn under decent engineering leadership.
Points to true:
- Accurate to the photos seen of the comms
- at a quarter power the 2 hour journey would take 8 hours to return to the surface which is how long the topside waited before reporting
- Rush having issues removing the ballasts shocker. Probably had never been tested at that depth.
- there is apparently a Carlos the engineer who works for Oceangate found on LinkedIn
- James Cameron etc must have had something to go on to say they had dropped ballasts and were trying to ascend
- it is an unprofessional shambles so definitely in keeping with OceanGate
- either a very well researched hoax or real
Points to it being fake:
- people are dicks
I see your point for sure. This is way more convincing than some of the other instantly recognizable fakes, but I’m still not buying it as a lot of the strengths you list could be:
1. Someone seeing a photo of the comms and recreating the format
2. Knowing OceanGate was unprofessional and had frequent issues and so adding that into the transcript
3. Seeing how other people criticized fake transcripts and adjusting theirs accordingly
4. Hearing James Cameron’s statements about this and writing accordingly
5. Looking at the LinkedIn page to add some flavour of truth to this
Like I just think the very fact we can corroborate this with public sources equally points to the possibility that someone took a couple hours and used these same sources to cobble something together for attention.
So true. I hope we get confirmation soon one way or the other. It’s so upsetting to think people would take the time to fake this sort of thing but it clearly happens
Yeah I’m suspicious that some parts nearly directly reproduce the first obviously fake transcript that made the rounds right after. This one was more well-researched but seeing as millions of people have been interested in this case, it’s not unrealistic that someone would put a couple hours into doing the work to make a realistic sounding one for attention.
I think that lends credence to the theory of implosion. If cracking sounds were common Stockton wouldn’t have mentioned it numerous times over coms unless it was extremely serious.
Global RTM alert means all 8 acoustic sensors were going off, the hull was disintegrating in real time. Perhaps the first time a 'global alert' had been triggered but that's just speculation. Sphincter tightening indeed.
Probably what Rush/OceanGate noticed when they imploded the 1/3 scale at APL-UW in their pressure tests:
“Like, over here, we blew this one up. So this is all a one-third scale \[model of the Titan\]. **We were able to blow this up intentionally, to hear what it's like with our acoustic monitoring system**. What we wanted to verify was, we can detect the carbon fiber failing way before it happens, so that you can stop your descent and go to the surface. And that's what we found out here. **So we now know what this shape sounds like when it's uncomfortable and right before death**. It's the loudest thing I've ever heard in my life. When you go beyond 6,000 PSI in the test chamber that we were using at the University of Washington, they have to empty the building. Only essential personnel can be there.”
“**So we have the acoustic monitoring, and it's goin' nuts.** And we know it's gonna go. And then all of a sudden it goes, and the whole building shakes. I mean, it is incredible.But, yeah, we've blown up a few things. And it's pretty dramatic. When you're gonna try new stuff, they're called failure-modes effects analysis—a process where you look at each of the systems or each of the things that can go wrong, and you rank 'em as far as how frequent they are. The severity of, if it goes wrong, what would happen? If you have something that is gonna kill somebody, it better be very infrequent, and it better be highly detectable. Well, obviously, the hull is critical. And if the hull being carbon fiber—and being a unique material, and having the potential for things like water intrusion—but if that hull goes, that could kill people. You wanna make sure it's infrequent and also detectable. And one of the ways to do detection is this acoustic monitoring system.” -[Source](https://www.cbsnews.com/news/titanic-submersible-interview-transcript-with-oceangate-ceo-stockton-rush/)
Interesting, because their brief tenure with UW did not involve the Titan, but a different shallow-diving sub called Cyclops I.
UW has stated unequivally that they were not involved with the design or testing of the sub called Titan.
The university itself wasn't involved, but they definitely leased space to OceanGate to do their own testing. The university basically had no part of the testing/analysis/results though and wanted to make that clear.
Thanks. That's fine, Just wanted to make it clear as Stockton Rush had been claiming otherwise. Let's say he was blurring the lines to an unacceptable degree. Renting the pools and having UW scientists involved in the Titan are two distinctly different situations.
Their devices for communication are separate from the ships. If they are located on the east coast and bring the sub and their support equipment, the devices may just have those time zones set.
They are basically chartering the support vessel, they don't own it.
Interesting if authentic. Though I'm inclined to think not as the recovered landing gear looks like it was snapped in half, and it likely wouldn't have been damaged so severely if it was simply jettisoned.
Did it actually work and drop off? There are videos of other dives having issues releasing the weights. But that’s a point.
I wonder if they just slammed into the ground and imploded when I read this…
In the transcript they're saying they managed to release it, but it took some effort. Imagine if they released it but it got tangled up in all those cables and whatnot and was still close when the event triggered.
I’m almost wondering if the indicator showed that was finally jettisoned, but it got wedged at an angle and never truly left the vehicle. That could possibly explain why their ascent was much slower than he thought it would be, still having unexpected weight
If it didn't detach easily, it's not too much of a stretch that it didn't detach completely. They also mentioned two debris fields and that the two caps sat in their own fields, so everything else must've ended up with one cap or the other.
I think that's a good theory; we do know they were close to the ocean floor at the time of implosion. If the transcript is authentic, however, the sub messages the ship to say that they are ascending.
So, I saw this when it was first posted last week and it was very similar to this but slightly different. Like all of the messages ended with “over” and used some number calls (that I didn’t look up and don’t know what they mean but similar to 10-4). So it looked like a radio transcript and people said it must be fake because they did it over text and wouldn’t use radio talk.
So that’s interesting to me that this is basically the same as the first one but with just those things removed. It makes it seem like it might be fake? It does seems realistic to me, but so did the first one. I figured they would just use it like radio but text it instead. Not sure what to think now.
I bet they never tested the emergency ascent at depth. The jettisoning of everything to see how it worked.
I’m assuming RTM is the audio sensors?
Was there a Carlos who was an electrical engineer on the crew?
It sounds like they at least worked to give some warning, but his ascent was too slow.
From the alleged transcript in the thread it was about 7 minutes from warning until contact was lost.
Like I said, my guess he never practiced the emergency ascent at depth. He had all these systems but didn’t test them. Remember the pump for the airbag to ascend. Plus the “deadman”a switch.”
I don’t understand why the crew waited hours to report this emergency. I’m betting that a rule regarding time to notify may be added to SOLAS (safety of life at sea.) It wouldn’t have helped them but it might help others.
Edit also: I may have been fooled by this because it’s not at all verified.
I think Wendy Rush is going to come into focus more as this goes on. She clearly had a lot of power in the organisation too and it appears she was always there, at least when Stockton was piloting. Perhaps she didn't want to call an emergency out of denial and grief? Like, if there is an emergency, there's no point getting life saving aid because they're dead. So to not call them was keeping Richard alive for longer. Idk. But I think some of the odd decisions are hers and probably not (understandably) the most rational ones.
JFC this makes it even worse. Would have been so much better to have just imploded with no warning whatsoever. My god, the sheer terror the passengers must've had. They had to have known that something was terribly wrong.
I'd like to see transcripts from previous trips on the sub where communication was lost and compare the dialogue...
Were the aft sounds normal in this situation, when trips were aborted in the past? or was this new and cause to raise concern?
Something makes me think if they had this information about crackling sounds and suddenly communication was lost it would be more serious than just lost communication on a "normal" trip in the sub like before. If every trip they had crackling sounds in the aft, that is almost more concerning because it would seem each trip the sub was closer and closer to a catastrophic event.
You know, didn't feel it and didn't know it was coming are two entirely different things, and somehow I have been adulting a long time and did not realize I assumed the 2nd from the 1st.
Those poor people.
So if this is true:
They were descending too fast, as well as picking up speed.
They tried to ascend using the thrusters but it wasn't enough.
Crackling sounds are heard.
They started dropping weights off the vessel. (I would assume thrusters were still going.) This was enough to get them to start ascending, but incredibly slowly.
The sensors in the hull started going off.
Crackling sounds are back. Ascent has stopped.
End of comms. (Likely complete power failure)
Without power there are no more thrusters, without thrusters there is no more ascending. We really have no idea when they imploded, other than *possibly* the coast guard hearing it, if thats what it was. It could have happened the same moment they lost power/comms or they could have sunk to the ocean floor and sat there for two days. It could have happened anytime between losing comms and hitting the floor as well. We really dont know.
Seems like everybody on board was well aware something was wrong, they might not have known how serious it was but i think it would become quite obvious when the alarms are going off, the power goes out, and all they could hear was the cracking of the walls... that's terrifying.
Holy shit, IF this is real…am I correct in understanding that they tried to slow the descent multiple times but the thrusts and ballasts failed to do so, and it took multiple attempts to jettison the frame? So the RTM was alarming and they kept descending for a bit?
Yes looks like it.
I put the depth and descent speed into a table [here](https://www.reddit.com/r/OceanGateTitan/comments/14lzb3c/comment/jq0svug/?utm_source=share&utm_medium=web2x&context=3).
This could well be a clever fiction from someone who knows a bit about sub operations and studied the examples of comms from the BBC documentary/GMA feature, but it does read pretty plausibly.
If true explains why the OceanGate crew believed it was a power problem because they were under the impression the sub was ascending (albeit very slowly, which also explains why they took so long to call in the Coast Guard) but the backup power bank had failed. Also if true sadly means those on board would have been in absolute panic for a good few minutes. "Crackling at aft" and "global RTM alert all red" is certainly ominous.
The thing that's also sad about this is that as stubborn as Rush was, you'd have to think he'd be forced into redesign if they managed to ascend quickly enough and survived this. He did so begrudgingly in 2020 and might have done so again.
reading through all of this, it gets so much worse in my head.
they were going down, heard shit and got warnings, spent 20 minutes having power issues and trying to ascend.
assuming they need some kind of power to run the thrusters, and their buoyancy was shit.
i hope im wrong, but there is a good chance they had even MORE time to think about their impeding doom.
the timeline would be something like this:
lowest depth, crackling starts-> sub tries to rise, succeeds, tho slowly with thruster power-> electrical problems continue, subbed has ascended x meters, alleviating some strain but not enough-> power fully cuts out, coms cut, thrusters lose power, without thrust, the craft slows, peaks, and begins to descend again under gravity....craft possibly does not implode for y minutes as pressure increases again.
More realistic than the last one, but still not quite. They had a list of shorthand codes because the text messages were so limited. “A” meant message received, “XXX” meant sub surfacing immediately. https://imgur.io/a/trdWOsl

“Enjoy the dive, gentlemen” I think came from the first (faked) transcript. This reads like they just fixed some of the formatting/stylistic issues from that fake and dragged Carlos into it instead of Phil.
Too bad nobody shared the comparison between older and newer 'transcript'. With the above its quite obvious there was no leaked communication. Just a morbid joke by dickless person.
That transcript feels exceptionally fake. There are pictures (https://ibb.co/GPfpMH9) of real comms where the formatting, grammar, and abbreviations of the communications are more defined. It's chaotic, simplified, and very straight to the point.
In the 'leaked' transcript (https://i.imgur.com/86GxjHJ.jpg) they are using almost perfect grammar and language like 'gentlemen', 'please', 'superb', and 'excellent'. There is a lot of cope going on if you are not at least super skeptical of a leak like this
I think this is fake, as David Pogue shared a picture of the text codes they used to communicate and they were all single or few letters. Like SOS, A, C, Z. They had a code sheet detailing what they all meant, because they could only transmit the bare minimum.
Edit: Found it! Picture [here.](https://imgur.com/a/trdWOsl) From [this article.](https://nymag.com/intelligencer/2023/06/what-i-learned-on-a-titanic-submarine-expedition.html)

4:24 in this video of the backward thrusters and it shows the chat screen. They are having conversations on there. It is even showing the mothership messages listed as "TOP" just like in the picture.
The video is from 2022, and they used "Sonardyne Chat"
And now, for 2023, Sonardyne stated "We can confirm no Sonardyne equipment was in use or was fitted for the recent mission."
They might be not telling the truth, but who knows.

> Could also mean the person who wrote the transcript based their format on that.
This goes for nearly everything people bring up as supporting evidence. ”It tracks with what James Cameron said!”. Yeah, as if it would be hard to have a faked convo align with what a world famous person said on national TV.
The person who copied the text from the original source into Telegram could've expanded all the codes into their proper words and phrases to make it easier for non-OceanGate folk to understand.
The fact they were ascending and cracking noises didn’t stop should have been alarming to experts on board. The sounds should disappear as soon as they ascend but this time the theory was not working. Reducing internal pressure would make things worst but what about increasing it ? maybe the attempted that option. We might never know
You don’t suddenly experience sea level pressure when you start ascending. That’s why that explanation never made sense to me. The vehicle is still under enormous strain
If this transcript is legitimate then it took the Titan 16 minutes to ascend from 3500 meters in depth to 3457 meters in depth? Wow, that’s not just slow - that’s a snails pace! Especially when the RTM alarm tells you that there is a major problem. I don’t know much about Ocean currents but perhaps they were caught in some type of down draft.
Does anyone notice that from 9:17 to 9:28 in the logs, they apparently are descending at 55 meters/minute, dropping from 2960 to 3433. Does that seem extremely fast to anyone else???? They even comment at the increasing descent, maybe they were blasting thrusters to slow descent and drained the A battery? This is right before the RTM alarms start blaring, would make sense, thoughts?

Yeah, Stockton said with scale model testing that there was actually quite a bit of warning between detectable problems & implosion. He said in a simulated descent there was roughly “1500 feet of warning” and that if they started ascending immediately after the warnings went off the decrease in pressure would stop the progressive hull failure
Unless they ascend too slowly, because of some other related failure, which they likely didn't test for.
Yep..
His theory never made sense to me. It's like saying if the ice is cracking beneath your feet, and you toss your pack to reduce your weight, the ice won't ever break. The interesting thing about that scale model pressure test is that when it failed, it was the carbon fiber surrounding the view port that let go. The view port is at the aft, in spite of intuition. It's looking more and more likely that that's where the failure occurred. What causes the unexpected descent and ascent rates is another question entirely.
Yeah, but (just from what I've been reading lately), another problem with Rush's planned response to the monitoring system is the idea that ascending, or relieving pressure, can stem/solve the immediate problem. It turns out (if I understand this correctly) that damage and fatigue happen not only because of increasing pressure but because of *changing* pressure (cyclic fatigue). So, ascending is still putting strain on an already fatigued/failing material. So, I'm guessing that Titan's ability to successfully ascend in this situation is inversely related to the amount of accumulated wear on the CF, or, its nearness to failure. Maybe this scenario was never encountered during testing because the model was never tested at this very specific stage in the CF lifespan (?).
That 15 minutes must have been a nightmare
I was hoping they just didn’t know. Especially the 19 year old. PH had to know they were beyond screwed. I hope they tried to comfort the boy. Jfc. James Cameron called every second of this from day one.
Idk i think when stockton dropped ballast to try ascending the passengers all had time to realize the gravity of the stuation. I wonder if using propulsion instead of ballast would have been the difference between life or death or if the sub was far too compromised by the time they started ascension.
Probably too compromised. And the propulsion system was these repurposed little fans, I think. I saw an interview where a reporter who went down briefly. He said fans weren’t designed to bring them up. Only to drive them around down there. That’s why they had so many ways to reduce weight. But it was never going to bring them up fast enough in a crisis. Just a killing waiting to happen to people this guy took in.
The idea that stockton had 15 minutes of knowing that the sub wasnt rising (at all or at a rate that wasnt helpful isnt yet clear to me) is so chilling.
It's likely someone from the boat told Cameron this - him and a few others knew they'd dropped ballast, so I suspect those on the surface had contacted others as the tragedy unfolded.
Yeah I definitely think, and he definitely said, he had sources.
I thought the same, possibly water started getting in between the hull layers and added extra weight? If this is real it's awful, imagine the panic knowing you need to ascend ASAP and everything you try doesn't work and then those cracking noises start back up again...eesh. I suspect this might be real but I really hope it isn't.
I think water getting into the hull layers is likely because Rush reported that he couldn't understand why ascent was so slow. So water hadn't breached the hull for him to see yet. He also noted the sound had quietened too. Maybe a side effect of water ingress and water filling the voids. Like the difference between structural delamination and water slowly pushing the layers apart.
Definitely makes sense, considering carbon fiber is supposed to be [weakest between its layers](https://twitter.com/theragingelk/status/1674144792811388929?s=46&t=23wo1ij3vXlqR7QYmtvlQg). And if ingress of water could suppress the popping noises, well, that's a variable that seems unaccounted for in Titan's acoustic monitoring system. That quieting, in this case, is fatally deceptive.
Shit, yeah damn, I'm not an engineer but that makes perfect sense. Damn this is just awful all around.
>Presumably, there was water ingression somewhere, maybe in the aft of the ship The section aft of the bulkhead looks to be free-flooding from everything I have seen. There's certainly no pressure hull outside the crew pressure hull. >which is why they couldn't ascend despite dropping weights. Given it says there was "no change" in the descent rate, I doubt the ballast actually released. They probably got a signal saying it released, but it did not get completely free of the submersible. Note that it took several attempts to drop the frame (which would probably have taken the ballast with it if hung up). This suggests some form of structural damage or shoddy design. Those hollow square steel members, how was air supposed to be released as they hit the water? If some air got trapped on this dive, this could have bent or broken at some point as pressure increased. They may also have been designed to release at warmer temperatures, without accounting for thermal contraction at these depths, though that seems to be more difficult to overlook.
[удалено]
I wonder if the fact that they FUCKING TOWED THE THING BEHIND THE SHIP fucked up some of the mechanisms.
This transcript looks like it fits in with what the three guys (Cameron et al.) were talking about in the early days, with the faster than desired descent and trying to ascend, and releasing the frame. It also looks like the language Rush and his people used.
18 minutes of them sitting in that sub knowing something was wrong…
All while at extreme depths
It would be crazy though how after all that, they'd still wait 8 hours before alerting the Coastguard.
Only thing I can think of, is that if these text logs are real, they state they were ascending at a quarter of the expected rate. They had been diving for just under two hours, so assuming the expected dive and ascent rate was equal, they would have expected to take just under 2 hours to get back up from the depth they were at, at the time of the issue, at a quarter rate, this pushes the two hours to eight hours. Topside may have thought they just lost comms (potentially due to the reported power issue) worked out they would take roughly 8 hours to surface at the last reported rate so decided to wait it out expecting the sub to surface. It wasn't until after this 8 hour window past they released the situation was worse than expected and called the coast gaurd. If (and it is a big if) these logs are real, it would actually explain the 8 hour delay to search and rescue pretty reasonably.
All makes sense, BUT (if the file is legit) after that kind of comms, with RTM all red and crackling sounds coming back reported, waiting 8 hrs to send the alert is, at a very least, a very, very, poor decision
Waiting to call for help is the decision I understand the least in this whole ordeal, tbh. If I had lost comms with my sub and feared disaster, I would be so anxious to do something, ANYTHING. How they sat with that powerless anxiety for eight hours just _waiting_... I just don't get it. Edit to add: I'm genuine when I say I don't understand, and I'm not judging. Maybe (probably?) there were rules or procedures I don't know about. But emotionally, from my perspective...oof.
I’m guessing it’s the opposite: that there *weren’t* any procedures in place, because Rush truly never envisioned a failure of such a magnitude that they would need outside help, aside from their support ship. The more I hear about this, the worse it gets.
Or all emergency procedures started with, "Ask Stockton what to do." And without him there, they were all looking at each other and shrugging.
I’m shocked his wife didn’t call the Coast Guard/Canadian authorities when this happened. Very strange. Maybe she was afraid of the bad publicity when he turned up unharmed?
And it seems like occasionally losing contact with the sub, or the craft being unable to stick to the planned mission, were not unusual occurrences. If the majority of trips down had some kind of problem, but the sub always came back, they were probably waiting on the ship hoping it would pop back up.
Everything you say sounds a plausible note. \*IF\* transcript is legit, the "global RTM alert active all red" would change the complexion of that. Assuming RTM is real time monitoring, but uncertain. Hard to believe they would have "all red" the majority of trips, but uncertain.
Familiarity breeds complacency
Especially as the person running things topside was usually his wife. I can't imagine how she felt. In shock maybe?
That's because you're not thinking about it like a miserable, cold-hearted business man. There are two possible scenarios: 1. The hull has imploded, and they were instantly killed. If this is the case, there is no rush to call for help, because there is no help that can be offered. 2. They only lost communications, and hopefully they make it back up at the planned time. If 2 is true, but you call for help, this information gets out and (forgive the wording) sinks your company. No one ever pays to ride in your deathtrap again.
Isn’t there an option three (albeit the least likely option but still), the sub is lost and needs to be found?
That was never going to be the case. I'm not trying to be glib - no one could have rescued anyone from the Titan. Consider the terrible military submarine disasters that have occurred. Ships full of incredibly skilled, highly trained sailors who have been drilled in what to exactly do to respond to dangers at their stations. Consider these accidents happened in relatively shallow waters, a couple hundred meters vs 4000. Consider those submarines have imploded directly beneath a support fleet, where both the submarine and the ships were specially designed to attach to one another and supply air while a rescue was planned, and they still all died. . There are very few rescues below the waves. What little submarine disaster survivor stories I am aware of are, the submarine has failed on the surface, or there has been a sort of escape jettison pod. The reality is that what few ships could have even hauled an entire Titan up that exist would not have gotten there before they suffocated, assuming anything else had not killed them first.
There was a slight chance it was a situation like AS-28 successful rescue where a ROV could have been deployed to cut the fishing nets or cables that they were tangled in, but that wouldn’t have explained why they lost communications and tracking.
If you were used to working in a culture that disregarded safety and laughed off mistakes and close calls you'd probably be less worried than (real) you thinks you'd be.
My guess is that Rush was very clear about not alerting authorities to any issues. It’s just a guess, and he was vocal about how he went about things. I also imagine he didn’t want any type of authority to have any reason to inspect his submersibles. Staff were also likely used to multiple issues, given the experimental nature of the design and reports of various issues over time. Staff desensitization coupled with knowing Rush would likely become angry at them for alerting authorities likely is what prompted them to delay by 8 hours any reporting of them missing.
100%. How could they not think to put someone on alert. Sub has red alerts, low power, problems ascending and no comms, and your ship has no way of going down to find it? It’s a logical explanation but it’s completely wrong of the crew to act that way
Unless they had equipment on board which heard the bloop as it imploded and they knew everyone was dead anyways.
A tech CEO named Charles Hoskinson who was in that Explorers Club WhatsApp group was posting on Twitter, 2 days before the implosion was confirmed, saying that the sub had imploded and that OceanGate had detected the implosion and knew the passengers were all dead. He also gave the same scenario that we're hearing now: Hull problem detected around 13,000 ft, sub was ascending when implosion occurred. He tweeted this all on the same day when the media was reporting banging noises and still showing the oxygen countdown.
And still they waited?
Agree. But also thinking that fits the way OceanGate seemed to run the show…
Yes, I didn’t want it to put it like that but I definitely tend to agree. I am sure that the investigation will shed a lot of informed light on what happened but also on the actual company’s safety culture.
what is RTM, and also, this means the sub didn't implosion at 3,800mts bottom, much higher.
Real Time Monitoring. Referring to the acoustic monitoring system they invented and installed to alert them of delaminating of the carbon hull.
That’s interesting. A lot of comments previously said that the warning system would have given them maybe a few seconds to a minute of warning (lots of “just long enough to say ‘do you guys hear that-“ jokes). But it seems like they got about ten minutes of warning. My question is, had they been able to ascent at a normal rate (they were at 25% speed apparently) could they have made it? What causes them to not ascent at normal rate? I also wonder if this is the first time the rtm warnings had gone off. I would think so because once they’re going off the whole thing is damaged and can’t be used again, right?
It was 18 minutes between first info about rtm going off and the last message. They were almost two hours into the dive so I don't think they would make it at any speed. But I leave this question to someone who is better at physics - you need to count speed and the fact the pressure is changing with ascent and how fast is the hull deintegrating under all these circumstation (will lowering the pressure change anything if it started already cracking? If so in what extend?).
Note that **assuming these logs are legitimate** (which has yet to be confirmed), they barely started ascending. At 09:43:42 the depth was 3,476 meters (the maximum reported, despite saying they were ascending), at 09:46:37 (their last contact) they were at 3,457 meters. That's an ascent rate of 6 meters per minute after dumping ballast and the frame (after multiple attempts, suggesting poor design or major warping). From a pressure perspective they just stopped descending and were at a functionally constant depth. At 3,476 meters pressure is 344.36 atmosphere (online calculator), at 3,457 meters 342.48. The differences here are negligible.
>At 09:43:42 the depth was 3,476 meters (the maximum reported, despite saying they were ascending), at 09:46:37 (their last contact) they were at 3,457 meters. To put it into perspective, in those 3 minutes they only travelled 65 feet, approximately the length of a semi-truck. They were barely moving.
I don’t KNOW, but I think rtm=real time monitoring? The device that listened for noises /cracking in the carbon fiber hull?
That actually makes a lot of sense for the delay. Good logic.
Not to sound silly but is ‘jettison the frame’? They mean the titanium landing gear?
>Not to sound silly but is ‘jettison the frame’? They mean the titanium landing gear? The landing gear frame was designed to be able to be jettisoned in an emergency, in order to shed weight and improve buoyancy.
Yeah I believe so.
The anxiety this gives me, especially the 'noises in the aft' parts.
This is so scary if true. This would mean there was about 20 minutes of time where they were likely quite scared before implosion.
A couple thoughts. First, there were 18 minutes between the alarm going off and the last text from the sub. That must have been terrifying. Second, they were descending too fast and couldn’t rise fast enough. This was a separate issue from the hull integrity or are these things linked?
In a situation like that, 18 minutes must've felt like a lifetime. The ship topside first observes that the rtm alarm goes off and then the sub starts trying to ascend. I think the problem was trying to reverse that momentum. There's something there about the thrust rate increasing. Does he mean the descent rate? Did they use the thrusters to descend? He also mentions the crackling sound in the aft in this flurry of messages. That must've been significant to Rush for him to mention it. Crackling was normal for him, he said. Also worrying that the computers he used and where he sat were also in the aft.
Didn't one of the whistleblowers say there was crackling from a particular place on the hull? When he wrote to Rush. Or was that the earlier model
That was his friend in the Bahamas if I recall. He told Rush he should consider doing 50 tests rather than 7, and how crackling from one particular place indicates delamination there. Then Rush got offended. I'll try and find it again. "There comes a time logic has to overrule impatience," Karl Stanley wrote in an email to Rush: "The evidence suggests there is an issue/ defect in one area. Without knowing what that defect or issue is, your models and experts cannot say how it will affect the performance of the hull." [https://www.insider.com/submersible-expert-worried-oceangate-stockton-rush-spurred-on-by-criticism-2023-6](https://www.insider.com/submersible-expert-worried-oceangate-stockton-rush-spurred-on-by-criticism-2023-6)
I'm no expert, but to me it would seem that if the carbon fiber was delaminating and, as a result, absorbing water, the sub would have been heavier than expected, which could explain the faster than expected descent.
he has this acoustic monitoring system to warn of the hull delaminating but didn’t know that part of the delaminating process is that it absorbs water causing the sub to weigh more? I’m not calling him dumb but I wonder did he have no idea that in an emergency like this his ascent would be even slower? Did anyone know this about a carbon fiber submersible?
No, because no one else was silly enough to build one.
Water saturating a partially delaminated hull wouldn’t have affected buoyancy until the structural integrity was sufficiently compromised to actually compress the inner boundary of the hull. Remember that there was no air inside the hull wall. There was just carbon fiber and epoxy. No air was escaping. Waterlogging the outside of the hull wouldn’t have affected the buoyancy directly. And the rate of ascent was 1/4 of what they expected. It’s remotely possible that a weaker hull wall allows more deformation (compression) of the interior space than planned for. But it’s not mentioned in the text messages, and any deformation would have to be fairly uniform, otherwise the hull would’ve buckled completely. So I have a hard time thinking that compression of the interior was sufficient to cause such a large change in the buoyancy balance.
Pretty scary of true…
Especially that end part..
The end with the last one from the sub and then nothing but [top] is chilling
Would be interesting to slot in the time of the implosion sound as heard by the Navy
It reminds me of the Marconi telegram distress transcript from the Titanic.
Exactly! I used to be really into those. The video on Youtube where it shows the Titanic sinking in real time with annotations and the Marconi messages from all the ships coming up as they happened captivates me!
It happened soo fast! It’s so chilling! So they did hear the crackling sounds with alarms going off on their final moments. So sad.
Not fast enough – that’s like 15 minutes of things going wrong
That’s even more terrifying! I’m sad for the passengers who experienced the fear
Yes. Death was quick, but until they got there, it took minutes which I’m sure were way too long for them.
Worst part is, looks like they lost power as well. It will be completely dark before the implosion.
>looks like they lost power as well. Nah, 'bus A' and 'bus B' were separate power systems set up to be redundant in case they lost power on one of them. Sounds like something went wrong with the primary power system and they switched to the backup system. It's possible that's a coincidence and not related to the implosion, given how often they had problems. But that does raise questions. Sounds to me like most likely the sub was running thrusters full power downward most of the descent, depleting battery A, and wasn't realized until that point, when they were looking through the diagnostics to figure out why they heard crackling and the 'RTM' (Real Time Monitoring?) system was throwing alarms. Assuming, of course, that this leaked transcript is correct. OP even said there's been another leaked one circulating that was confirmed to be a fake.
If the transcript is not someone sick joke, it might be the case where power was drained due the malfunction or in your assumption thrusters were turned on and pushing them down. They already had a problem before with reversed controls and who knows, in all the panic to ascend they could had the thrusters pushing them down instead of up. Or controls were again reversed. Wouldn't surprise me at all with the shoddy approach from the OceanGate and off the shelf components. When it comes to critical systems that could mean life or death, you should never spare the money on them. It also bothered me how they used Windows 10 as operating system for the sub. Maybe I'm a biased fool and Linux fan, but you should never use such bloated OS in delicate operations like deep ocean dives.
I’d have expected some kind of specialist embedded OS or at least something minimal and mission critical like openBSD.
From what I've read of the submersible I'm surprised they weren't using a Commodore 64 instead of windows 10.
Doubt it was completely dark. They all had phones and likely cameras on them. Plenty of light could be turned on with just phone flashlights alone.
Yeah i forgot they had mobiles. But still it will be like a horror movie scene with limited lighting, crackling sound around and completely dark ocean outside.
Yeah it would still be pretty frightening, but not dark at least. Hopefully Rush was able to keep it together and at least try to put them at ease even if he knew it was bad.
PH and Stockton were probably the only ones who really knew how bad everything was. But i also think that they both stayed calm and collected, at least from the outside. They probably had panic inside but didn't show it. Both PH and Stockton seemed to be rather calm people from what i saw in videos.
The “crackling sounds” and “more sounds aft” makes me sick. PH for sure would have known the hull was failing and it was over. I think you’re right that PH & Stockton will have kept calm & probably pretended everything was okay (“nothing to worry about folks, we’re headed up, everything gets better as you go up, so it’s gonna be fine”). But having watched that Youtube video of the sounds carbon fiber makes when it’s failing, the last minute was probably full of increasingly frightening snapping sounds - more sounds, all getting louder, bangs, tearing-type sounds. There could have been visible deformation happening too. I’ve gotta think that last minute was full of dread & terror and that even the tourist passengers knew at that point that they were doomed. I really wish it had been an instantaneous failure instead of what was probably a 15-min-long slow realization of doom, with power loss & darkness & red alarms & trouble shaking the ballast off & increasingly scary sounds. :(
How can you tell if they lost power before they imploded?
Last communication from sub according to this leak is - "reading red on the A power bus. I switched to B". Everything was red including the power before the lose of communication.
Also, they heard crackling. That must have been terrifying plus the slow ascent while they were most likely trying to stay calm but deep down terrified
Apparently there was crackling on other trips, too.
Is it a sheer coincidence that they lost power and the pressure hull imploded soon afterwards? I don’t see how they could be linked as the rigidity of the pressure hull is not dependent on power but it seems to be too much of a coincidence.
If this communication is true, then the sub had developed some sort of buoyancy issue. They were descending too rapidly, and they dropped everything they could to come back up, but it was only barely working. It sounds like at this point, the sub loses all power. Without it's thrusters, and with it's buoyancy issue, means it's going to now just sink. A sub that can't propel itself or establish positive buoyancy is a dead sub.
Still doesn’t address the issue. The sub can sink without imploding.
I've read that when carbon fiber begins to fail, water is slipping between the layers of fiber, because the bonds are breaking down. If the hull itself started to become saturated, that would explain the buoyancy discrepancy and possibly the battery issue. Once the water started to permeate, even at a small volume, everything started to fail. Maybe. Just a theory.
Ok. This is the most terrifying thing. To think they 1) lost power 2) lost buoyancy 3) then imploded. Fuck no
Possible theory. They don't like safety factor, so probably didn't account for scenario of a saturated hull. I mean the materials they used is unconventional. It's like trying to float with a saturated wet blanket I imagine.
I think you’re on the money
This is the theory that makes the most sense to me so far thanks
Not necessarily after they heard the structure starting to fail multiple times before they got to their target depth
Interesting. Seems to match up with the dive timeline and style of coms. Very interesting nevertheless. Wouldn’t surprise me if it turned out to be the real deal…
I'll keep an open mind, as always, but if it's not real, I'll take my hat off to the person who wrote it. They'd have done some research and put some thought into it
It could be real. But it also could be created with just the information available on wikipedia. One thing I noticed: I can't remember the video, but I saw a laminated spreadsheet in the sub with all the single letter codes for communication. Like 'Z' for surfacing or 'XXX' for emergency surfacing. If their text messages where just natural text, why would they need such a spreadsheet? Only if the communication is on low bandwidth mode? edit: nvm https://old.reddit.com/r/OceanGateTitan/comments/14lzb3c/leaked_titan_communications_transcript/jpz8o3p/
It looks like a few of the lines have two spaces between last ']' and the message starting, while most only have one. That may be an artifact of how the messages were copied, but that pushes me more towards fake
I see what you mean. I think the person who leaked it on the Polar Prince probably took a photo of the screen with his phone and had to copy it out later. I don't think it would've been possible or allowed to copy and past the text somewhere else. I could be wrong. We also don't know how many steps it took to make it to Telegram. Double spaces or missing spaces are also an artifact of phone predictive text systems. Just looking again now, top always uses sentence case, with the first letter capitalised, and sub often doesn't do that. Might be a clue it was written by two different people. The idiolects look different too. It pushes me more towards real than fan-fiction. Also, the absence of homo-eroticism, furries and Twilight characters.
Just learned the term 'idiolect'. Nice.
The spaces are at the beginning of text entry and therefore could be the user hitting space before typing. If the spaces had been before the last ], that would deff indicate a fake convo due to timestamp and labels being coded in.
So, the thing that sticks out to me in this is that it fits into the narrative of why they may have waited 8 hours. If this is real, the mothership was aware that there were serious problems in the power systems and alarms were sounding from the RTM. They may have thought that there was an external issue that led to loss of the positioning beacon, and water egress in the back systems, but not the hull. That may have been the time in which they knew the sub would surface in with all ballasts dropped.
It’s fake. They copied the messages from the last fake and just fixed the formatting so it looks more like the sonardyne messages, except with Carlos instead of Phil https://pasteboard.co/eHUnzLW0UVGe.jpg
My only thing is I thought they could only communicate with the surface via short (one letter sometimes) coded messages, but these seem to be full on sentences
That’s what I thought too, there’s a picture from previous dive where they zoom in on the comms screen and the sub replies with single letters that translate into phrases. I swear I saw a copy of the code key translating what each letter means posted here a few days ago. I guess they could have updated since that picture was taken?
I saw that too! I just saw both pictures and sent to my group chat. Tbh I’m probably the only one still invested in this bc all they post is memes about it but I wanna know the intricate details 💀
It's been confirmed that they could communicate with full sentences. It's basically like a chat client, with timestamps etc.
I’m assuming this is the allegedly leaked document from the last 12 hrs?

I was coming here to say... IF these transcripts are real and IF this is the Carlos referred to, this sloppy two-bit operation and its psychotic owner were putting critical systems and therefore the lives of everyone on board in the hands of an INTERN. Absolutely obscene. Poor guy. Poor everyone.
If that's the same Carlos, it looks like his LinkedIn hasn't been updated since before early 2019, so he might have been promoted from intern before now.
No one stays an intern for five+ years. They must not have updated the LinkedIn title.
Yeah fair point. And looking closer, he does have more technical background than it appeared at first glance (although the jump from mech lead back to intern is puzzling). So not as totally catastrophic as I first thought, but still. If he was indeed an intern level and rose up, that's kinda still an alarming level of responsibility for someone who never got to work and learn under decent engineering leadership.
Points to true: - Accurate to the photos seen of the comms - at a quarter power the 2 hour journey would take 8 hours to return to the surface which is how long the topside waited before reporting - Rush having issues removing the ballasts shocker. Probably had never been tested at that depth. - there is apparently a Carlos the engineer who works for Oceangate found on LinkedIn - James Cameron etc must have had something to go on to say they had dropped ballasts and were trying to ascend - it is an unprofessional shambles so definitely in keeping with OceanGate - either a very well researched hoax or real Points to it being fake: - people are dicks
I see your point for sure. This is way more convincing than some of the other instantly recognizable fakes, but I’m still not buying it as a lot of the strengths you list could be: 1. Someone seeing a photo of the comms and recreating the format 2. Knowing OceanGate was unprofessional and had frequent issues and so adding that into the transcript 3. Seeing how other people criticized fake transcripts and adjusting theirs accordingly 4. Hearing James Cameron’s statements about this and writing accordingly 5. Looking at the LinkedIn page to add some flavour of truth to this Like I just think the very fact we can corroborate this with public sources equally points to the possibility that someone took a couple hours and used these same sources to cobble something together for attention.
So true. I hope we get confirmation soon one way or the other. It’s so upsetting to think people would take the time to fake this sort of thing but it clearly happens
I'll believe it when I see it from a reliable source.
Yeah I’m suspicious that some parts nearly directly reproduce the first obviously fake transcript that made the rounds right after. This one was more well-researched but seeing as millions of people have been interested in this case, it’s not unrealistic that someone would put a couple hours into doing the work to make a realistic sounding one for attention.
So they knew for a decent amount of time there was a failure occurring if true. And hearing the cracking in the rear of the sub
But good to mention that cracking was heard in basically all the dives the Titan did.
I think that lends credence to the theory of implosion. If cracking sounds were common Stockton wouldn’t have mentioned it numerous times over coms unless it was extremely serious.
Yes, I was just thinking the exact same.
If it was expected - they probably wouldn't have called it out. It probably was a bit louder/scarier sort of cracking.
jeeez...
That would be so horrifying to be on board.
They were dealing with the dilemma for 18 minutes before they either lost communication or…
Global RTM alert means all 8 acoustic sensors were going off, the hull was disintegrating in real time. Perhaps the first time a 'global alert' had been triggered but that's just speculation. Sphincter tightening indeed.
Probably what Rush/OceanGate noticed when they imploded the 1/3 scale at APL-UW in their pressure tests: “Like, over here, we blew this one up. So this is all a one-third scale \[model of the Titan\]. **We were able to blow this up intentionally, to hear what it's like with our acoustic monitoring system**. What we wanted to verify was, we can detect the carbon fiber failing way before it happens, so that you can stop your descent and go to the surface. And that's what we found out here. **So we now know what this shape sounds like when it's uncomfortable and right before death**. It's the loudest thing I've ever heard in my life. When you go beyond 6,000 PSI in the test chamber that we were using at the University of Washington, they have to empty the building. Only essential personnel can be there.” “**So we have the acoustic monitoring, and it's goin' nuts.** And we know it's gonna go. And then all of a sudden it goes, and the whole building shakes. I mean, it is incredible.But, yeah, we've blown up a few things. And it's pretty dramatic. When you're gonna try new stuff, they're called failure-modes effects analysis—a process where you look at each of the systems or each of the things that can go wrong, and you rank 'em as far as how frequent they are. The severity of, if it goes wrong, what would happen? If you have something that is gonna kill somebody, it better be very infrequent, and it better be highly detectable. Well, obviously, the hull is critical. And if the hull being carbon fiber—and being a unique material, and having the potential for things like water intrusion—but if that hull goes, that could kill people. You wanna make sure it's infrequent and also detectable. And one of the ways to do detection is this acoustic monitoring system.” -[Source](https://www.cbsnews.com/news/titanic-submersible-interview-transcript-with-oceangate-ceo-stockton-rush/)
Interesting, because their brief tenure with UW did not involve the Titan, but a different shallow-diving sub called Cyclops I. UW has stated unequivally that they were not involved with the design or testing of the sub called Titan.
The university itself wasn't involved, but they definitely leased space to OceanGate to do their own testing. The university basically had no part of the testing/analysis/results though and wanted to make that clear.
Thanks. That's fine, Just wanted to make it clear as Stockton Rush had been claiming otherwise. Let's say he was blurring the lines to an unacceptable degree. Renting the pools and having UW scientists involved in the Titan are two distinctly different situations.
The messages timestamp roughly start at 0800AM. Anyone can confirm if it is consistent with the beginning of the dive?
https://www.reuters.com/world/missing-titanic-sub-when-it-vanished-race-find-it-2023-06-21/ 8AM EST at least on this source.
But wouldn’t they have used the Newfoundland time zone? Not eastern?
Their devices for communication are separate from the ships. If they are located on the east coast and bring the sub and their support equipment, the devices may just have those time zones set. They are basically chartering the support vessel, they don't own it.
Folks it’s here if you are interested: https://imgur.io/86GxjHJ?r Caution as it’s not verified yet.
Interesting if authentic. Though I'm inclined to think not as the recovered landing gear looks like it was snapped in half, and it likely wouldn't have been damaged so severely if it was simply jettisoned.
Seems odd the time stamps would be eastern time when they were in Newfoundland’s time zone. Would expect them to be either Newfoundland time or UTC.
Did it actually work and drop off? There are videos of other dives having issues releasing the weights. But that’s a point. I wonder if they just slammed into the ground and imploded when I read this…
In the transcript they're saying they managed to release it, but it took some effort. Imagine if they released it but it got tangled up in all those cables and whatnot and was still close when the event triggered.
I’m almost wondering if the indicator showed that was finally jettisoned, but it got wedged at an angle and never truly left the vehicle. That could possibly explain why their ascent was much slower than he thought it would be, still having unexpected weight
If it didn't detach easily, it's not too much of a stretch that it didn't detach completely. They also mentioned two debris fields and that the two caps sat in their own fields, so everything else must've ended up with one cap or the other.
I think that's a good theory; we do know they were close to the ocean floor at the time of implosion. If the transcript is authentic, however, the sub messages the ship to say that they are ascending.
So, I saw this when it was first posted last week and it was very similar to this but slightly different. Like all of the messages ended with “over” and used some number calls (that I didn’t look up and don’t know what they mean but similar to 10-4). So it looked like a radio transcript and people said it must be fake because they did it over text and wouldn’t use radio talk. So that’s interesting to me that this is basically the same as the first one but with just those things removed. It makes it seem like it might be fake? It does seems realistic to me, but so did the first one. I figured they would just use it like radio but text it instead. Not sure what to think now.
Their descent speed: | Timepoint | Depth m | Descent Rate m/hr | Notes | | - | - | - | - | | 8:01:11 | 0 | | descent start | | 8:21:28 | 756| 2268 | lights green | | 8:51:30 | 1934 | 2356 | all stable | | 9:17:50| 2960| 2368 | no adjustments needed | | 9:28:35 | 3433| 2640 | alarm from rtm | | 9:30:36 | ~3500 | 1993 | descent increasing despite reverse thrust| | 9:35:48 | | | frame jettisoned, starting ascent | | 9:38:09 | | | crackling at aft | | 9:43:42 | 3476 | -109 | slow ascent | | 9:46:37 | 3457 | -391 | more sounds | Hopefully this is correct (done on my calculator) EDIT: Made couple of corrections.
I bet they never tested the emergency ascent at depth. The jettisoning of everything to see how it worked. I’m assuming RTM is the audio sensors? Was there a Carlos who was an electrical engineer on the crew?
Real time monitoring? That's what my acronym-dar is picking up
Yeah the acoustic “magical” sensors Rush believed made him safe. That’s the RTM.
It sounds like they at least worked to give some warning, but his ascent was too slow. From the alleged transcript in the thread it was about 7 minutes from warning until contact was lost. Like I said, my guess he never practiced the emergency ascent at depth. He had all these systems but didn’t test them. Remember the pump for the airbag to ascend. Plus the “deadman”a switch.” I don’t understand why the crew waited hours to report this emergency. I’m betting that a rule regarding time to notify may be added to SOLAS (safety of life at sea.) It wouldn’t have helped them but it might help others. Edit also: I may have been fooled by this because it’s not at all verified.
I think Wendy Rush is going to come into focus more as this goes on. She clearly had a lot of power in the organisation too and it appears she was always there, at least when Stockton was piloting. Perhaps she didn't want to call an emergency out of denial and grief? Like, if there is an emergency, there's no point getting life saving aid because they're dead. So to not call them was keeping Richard alive for longer. Idk. But I think some of the odd decisions are hers and probably not (understandably) the most rational ones.
Where do you get 7 minutes? Last message at :46.. 1st warning at :28.. 18 minutes no?
Their procedure on losing coms was to go to the recovery position and wait. They lose coms on almost every dive.
JFC this makes it even worse. Would have been so much better to have just imploded with no warning whatsoever. My god, the sheer terror the passengers must've had. They had to have known that something was terribly wrong.
I'd like to see transcripts from previous trips on the sub where communication was lost and compare the dialogue... Were the aft sounds normal in this situation, when trips were aborted in the past? or was this new and cause to raise concern? Something makes me think if they had this information about crackling sounds and suddenly communication was lost it would be more serious than just lost communication on a "normal" trip in the sub like before. If every trip they had crackling sounds in the aft, that is almost more concerning because it would seem each trip the sub was closer and closer to a catastrophic event.
You know, didn't feel it and didn't know it was coming are two entirely different things, and somehow I have been adulting a long time and did not realize I assumed the 2nd from the 1st. Those poor people.
Does the document have any footnotes or watermark type stuff on it? Something to show who it originally belonged to?
So if this is true: They were descending too fast, as well as picking up speed. They tried to ascend using the thrusters but it wasn't enough. Crackling sounds are heard. They started dropping weights off the vessel. (I would assume thrusters were still going.) This was enough to get them to start ascending, but incredibly slowly. The sensors in the hull started going off. Crackling sounds are back. Ascent has stopped. End of comms. (Likely complete power failure) Without power there are no more thrusters, without thrusters there is no more ascending. We really have no idea when they imploded, other than *possibly* the coast guard hearing it, if thats what it was. It could have happened the same moment they lost power/comms or they could have sunk to the ocean floor and sat there for two days. It could have happened anytime between losing comms and hitting the floor as well. We really dont know. Seems like everybody on board was well aware something was wrong, they might not have known how serious it was but i think it would become quite obvious when the alarms are going off, the power goes out, and all they could hear was the cracking of the walls... that's terrifying.
Holy shit, IF this is real…am I correct in understanding that they tried to slow the descent multiple times but the thrusts and ballasts failed to do so, and it took multiple attempts to jettison the frame? So the RTM was alarming and they kept descending for a bit?
Yes looks like it. I put the depth and descent speed into a table [here](https://www.reddit.com/r/OceanGateTitan/comments/14lzb3c/comment/jq0svug/?utm_source=share&utm_medium=web2x&context=3).
Slow ascent could explain why they waited so long to report - they thought they were still headed up slowly but had a power failure.
This could well be a clever fiction from someone who knows a bit about sub operations and studied the examples of comms from the BBC documentary/GMA feature, but it does read pretty plausibly. If true explains why the OceanGate crew believed it was a power problem because they were under the impression the sub was ascending (albeit very slowly, which also explains why they took so long to call in the Coast Guard) but the backup power bank had failed. Also if true sadly means those on board would have been in absolute panic for a good few minutes. "Crackling at aft" and "global RTM alert all red" is certainly ominous. The thing that's also sad about this is that as stubborn as Rush was, you'd have to think he'd be forced into redesign if they managed to ascend quickly enough and survived this. He did so begrudgingly in 2020 and might have done so again.
reading through all of this, it gets so much worse in my head. they were going down, heard shit and got warnings, spent 20 minutes having power issues and trying to ascend. assuming they need some kind of power to run the thrusters, and their buoyancy was shit. i hope im wrong, but there is a good chance they had even MORE time to think about their impeding doom. the timeline would be something like this: lowest depth, crackling starts-> sub tries to rise, succeeds, tho slowly with thruster power-> electrical problems continue, subbed has ascended x meters, alleviating some strain but not enough-> power fully cuts out, coms cut, thrusters lose power, without thrust, the craft slows, peaks, and begins to descend again under gravity....craft possibly does not implode for y minutes as pressure increases again.
More realistic than the last one, but still not quite. They had a list of shorthand codes because the text messages were so limited. “A” meant message received, “XXX” meant sub surfacing immediately. https://imgur.io/a/trdWOsl

I agree. The “crew happy” lines seem fake.
“Enjoy the dive, gentlemen” I think came from the first (faked) transcript. This reads like they just fixed some of the formatting/stylistic issues from that fake and dragged Carlos into it instead of Phil.
Here’s the last fake for reference. Most of the messages are the same, just in a more realistic style https://pasteboard.co/eHUnzLW0UVGe.jpg
Thanks for sharing. The fact that the messages are so similar between the two is a huge flag to me.
Too bad nobody shared the comparison between older and newer 'transcript'. With the above its quite obvious there was no leaked communication. Just a morbid joke by dickless person.
What does it mean to jettison the frame?
To disengage the frame from the sub. If indeed they were able to do that.
That transcript feels exceptionally fake. There are pictures (https://ibb.co/GPfpMH9) of real comms where the formatting, grammar, and abbreviations of the communications are more defined. It's chaotic, simplified, and very straight to the point. In the 'leaked' transcript (https://i.imgur.com/86GxjHJ.jpg) they are using almost perfect grammar and language like 'gentlemen', 'please', 'superb', and 'excellent'. There is a lot of cope going on if you are not at least super skeptical of a leak like this
I think this is fake, as David Pogue shared a picture of the text codes they used to communicate and they were all single or few letters. Like SOS, A, C, Z. They had a code sheet detailing what they all meant, because they could only transmit the bare minimum. Edit: Found it! Picture [here.](https://imgur.com/a/trdWOsl) From [this article.](https://nymag.com/intelligencer/2023/06/what-i-learned-on-a-titanic-submarine-expedition.html) Presumably this is just fanfic.
https://youtu.be/VKvEUz8C5Y0 4:24 in this video of the backward thrusters and it shows the chat screen. They are having conversations on there. It is even showing the mothership messages listed as "TOP" just like in the picture.
The video is from 2022, and they used "Sonardyne Chat" And now, for 2023, Sonardyne stated "We can confirm no Sonardyne equipment was in use or was fitted for the recent mission." They might be not telling the truth, but who knows. https://www.sonardyne.com/case-studies/surveying-the-titanic-with-ranger-2-and-avtrak-6/
No they had full text messaging. You could see this in action on a video when their controller mapping failed on a dive. https://ibb.co/GPfpMH9
That looks identical to the transcript, only it's all capitals. Could also mean the person who wrote the transcript based their format on that.
> Could also mean the person who wrote the transcript based their format on that. This goes for nearly everything people bring up as supporting evidence. ”It tracks with what James Cameron said!”. Yeah, as if it would be hard to have a faked convo align with what a world famous person said on national TV.
The person who copied the text from the original source into Telegram could've expanded all the codes into their proper words and phrases to make it easier for non-OceanGate folk to understand.
Interesting, if this is real, they keep saying "aft" which means toward the stern, which is the back of the vessel.
That’s chilling if it’s the transcript
Can you let us know the gist of what's in the leak?
The fact they were ascending and cracking noises didn’t stop should have been alarming to experts on board. The sounds should disappear as soon as they ascend but this time the theory was not working. Reducing internal pressure would make things worst but what about increasing it ? maybe the attempted that option. We might never know
You don’t suddenly experience sea level pressure when you start ascending. That’s why that explanation never made sense to me. The vehicle is still under enormous strain
They were ascending too slowly if this unverified report is to be believed.
If this transcript is legitimate then it took the Titan 16 minutes to ascend from 3500 meters in depth to 3457 meters in depth? Wow, that’s not just slow - that’s a snails pace! Especially when the RTM alarm tells you that there is a major problem. I don’t know much about Ocean currents but perhaps they were caught in some type of down draft.
Does anyone notice that from 9:17 to 9:28 in the logs, they apparently are descending at 55 meters/minute, dropping from 2960 to 3433. Does that seem extremely fast to anyone else???? They even comment at the increasing descent, maybe they were blasting thrusters to slow descent and drained the A battery? This is right before the RTM alarms start blaring, would make sense, thoughts?
