This transcript would give the appearance of a lack of panic onboard Titan. Here one second - into oblivion in the next. That has to be of some comfort to the families... we do know that at the moment of implosion there would be zero time for the passengers' brains to even register destruction. Or so we would all like to think for the sake of the passengers. It seems more likely to me that Stockton Rush did not relate the exact situation inside the submersible to the Polar Prince . Titan does appear to have been descending too fast .. not as fast as initially claimed in the fake transcript - but still too fast. Do we know if it was normal to release the two weights when they did (just prior to implosion)? It just doesn't make sense to release weights unless they needed to ascend... But without any real communications of what was actually happening onboard - this just raises more questions than ever!!!
@@JoeLinux2000 For starters, Why'd the Polar prince not know what the payload was prior to launch? Then no response about the location pinging all over the place. No one was coordinating properly. Once asking for them to write down time and depth, Rush replies with No, i didn't bring/clean the niskin bottle. I could go on...
They were probably begging to go back up and he was probably refusing going on about how adventurous he was. Then the noise started scaring him too and he dropped two weights but it was too late at that point.
It seems to me that comms simply worked badly (often no signal reached PP or signal arrived truncated at TTN) but it was accepted as fact of life (for instance they ask a few times for evologics but then stop for a while). I think that TTN was completely unaware.
Right when you're being told that your position is changing drastically it is not the time to to say that the instrument that gives your position was NEVER cleaned - I would think that the others on board at that point knew they were screwed
I remember reading a testimony about when one thruster was mounted backward after maintenance; well first the fact they didn't tried the sub before being underwater with paying passengers tells alot, right? But yeah, one customer said that Stockton struggled with the unfamous controller, and someone else aboard tried to tell Stockton to try something else. Apparently it tool over one hout until Stockton gave up and handed the controller, and the situation was resolved. So yeah I wouldn't be surprised to learn that in this dive, the software crashed, Stockton just used his superpowers to ignore the situation until his super willpower solved it, and when nothing happened, PH took control and reset the software and reestablished communications, explaining why he answered at this point.
Chat stopped because a wire leading out the rear ring of the sub was degrading, Stockton handed over the keyboard, he pulled the wire out the computer to reset it, kinda pulled it because he could hardly see, plugged it back in.. thats where the leak started. Final answer I'm calling it right now!
Yeah really! like how would they know that detail 1000 meters under water off the top of his head? that should have been known before even leaving the PORT!
the term 'payload' is not related to ship payload here. It might be data payload and most probably related to the USBL line between the vessel and the ship
@@khit007 I was more referring to how unproffessional the actual transcript is. I mean, they sent the same message over and over and over again, yet they didn't bother to answer. But when asked for a comms check, they answered right away.
I mean, we all gonna die eventually. I just found out about a wild animal shelter TH-camr, who recently passed away in the shelter, by simply falling off his ladder, which caused him a coma, leading to his death. Still beats being turned into a toothpaste, in a metal coffin underwater at 12,000 ft tho 😂😂
@@moviemaker2011z Why do you need to see the Titanic from inside a submarine? You can't get out and walk around so using an unmanned sub with a really good camera seems about the same to me.
5:01 "What is your dive payload". It seems strange to me that the mother ship does not have this info. Isn't this something that should be known to all before the dive even starts? This is a bit like Houston asking a manned space rocket while it is alread in flight, "what is your payload?" Later something similar happens with regards to "the niskin bottle" (whatever that is) TTN replies with "no Niskin, never cleaned....." Again shouldn't this be something the mother ship should have been aware of BEFORE the dive even started? To me this looks like the mother ship and the submersible weren't integrated properly into a functioning unit. And I guess there weren't many checklists either. A suicide mission.
Per Google: Niskin bottles are used to collect discrete water samples for a range of measurements including pigments, nutrients, plankton, etc. The open bottle is lowered into the ocean on a wire from a Research Vessel until it reaches a certain depth and then the bottle is closed by a weighted trigger (called a "messenger") that is sent down the cable from the surface. Niskin bottles are neither cheap nor particularly easy to use.
The suspicion is they carried one Niskin bottle as part of their cover of pretending to be a “research” vessel “see we took a sample from the bottom, science!”
So they went instantly, no horrific last moments. Since they were so close they were probably all concentrating excitedly on the Titanic coming into view any second and
The third witness. The older gentleman said in his testimony that the final weights that were dropped was a standard procedure that may have been done early to help things go smoothly and that they did not drop enough weight to indicate they needed to resurface. He said that was a standard weight drop to slow descent.
@@Oops-IMeantToDoThat he said that normal would be 100 meters above the floor, but SR most likely dropped weights at 300 meters to ensure that they will slow down gradually, not hit the floor and it will be as comfortably as possible for passengers. With dropping weights at 100 meters there is a chance to hit the floor a bit, which is not a big deal but can be uncomfortable.
@@kreterakete I don’t think the last comms is a good indicator of the exact time of implosion (unless it’s been confirmed by nearby acoustics/sonar arrays.)
This might be considered a hot take, but Rush shouldnt be part of that memoriam. He is the one that caused those deaths, and is one of the rare cases where I will state that Rush deserved what he got, the others on board, did not.
he deserves to be, his sub still managed to visit Titanic 13 times. Dozens of people had their dreams fulfilled thanks to him. Now his failure is a lesson to other geniuses
Yeah I don't know why everyone keeps including him in the RIP. What respect has he earned by charging people hundreds of thousands of dollars to lure them to their deaths with his own stupid incompetence?
the best thing ive heard from the court hearings is that the one guy that got fired said there were tiny holes in the hull so they took it out to an open parking lot and wrapped the hull in a TENT and Rhino Liner for the bed of a truck to prevent it from leaking literally all the engineers at that point should said "Hold up this has got to be the dumbest thing ive ever heard I Quit!"
@@highjinx6519 honestly the only good thing stockton rush has did for me is i know alot more about carbon fiber and what its best and worst uses for application is haha
@@Davehash Only if their weight surpassed the thrusters' capabilities of lifting them back up. The vehicle being above capacity would indeed increase uncontrolled descent acceleration though, along with making it take longer, if not impossible, to ascend to the surface again. I've seen a few videos saying about thruster failure, so they could have suffered a failure, descended without control and slammed into the ocean floor if everything else failed. The fact they also let go off of two weights implies a few things.
There goes jeff again, covering all the most relevant bits we're most interested in. You're near the top when you search this topic too, nice. Appreciate you, friend 🙏
What are you basing that on? These investigations take a long time to conduct and then even longer to put the presentation together. Believe it or not, it's good that these take a long time because it means they're being thorough. Look at air crash investigations they take years sometimes.
The comms look really confused. Why is Paul-Henri on the comms when he seems unfamiliar with the proceedures? Was Stockton just ignoring the messages? Why is the mothership asking about dive payload halfway through the descent? Why are they asking to deploy a Niskin bottle that was not taken on the sub? Why wouldn't the team on the Polar Prince already know this? Did they just throw out checklists entirely? This is wild.
@@muggsyd That seems a little too dramatic, doesn't it? Seems more likely to me that Stockton just wasn't particularly interested in his responsibilities. Ignoring his smaller responsibilities lead to confused messages. Ignoring his larger responsibilities cost him his life.
This is such a strange conversation - making insane repeated typing mistakes like m/sec instead of m/min is insane (if you have practiced this 500 times there is no way you will think 33m/s makes sense and actually hit send)
I don’t remember seeing a keyboard in publicity shots. They might have been using the game controller to type from a virtual keyboard. One thing I noticed (especially if they were using game controller) was they didn’t use more acronyms for standard messages; “what is your depth” typed as wid, etc. fewer chars, less Chance comm garbled - can always ask for clarification.
Here is my opinion: He thought that since the Titan had successfully made the same dive several times before, then it must be strong enough. In his mind, that history of success overrode all the warning signs.
Exactly. The other 3 are victims of murder and that's it. Stockton.. Well, atleast the murderer is dead as well. PH... I don't understand why he'd get into this playstation controlled deathtrap, he should've known better. I gues all that's left to say is, i hope the impact was as fast as everyone says and all murder victims in this case never noticed anything wrong before they died. so that they didn't have pain or fear or whatever.
thank you. take it from his f*cking billion dollar estate. what the hell? I am gonna die 30 years early because I'm broke but here, take my money for this farce.
Idk man I kinda have to disagree. For one, the money was "already spent" regardless of the titan sub implosion happening or not. It's not like if it hadn't happened, the tax payer would be out less money; the coast guard has a budget, employees, and resources that are already allocated for SAR activities during a given fiscal year.
@@unimoose I completely agree with you. These kinds of operations are called “living in a modern society”. By those people’s logic, should we also charge hikers tens of thousands of dollars when they end up lost and stranded while exploring a national park? Should seniors get charged for rescue and vehicle recovery when they keep continuously drive into the lake surrounding a roundabout that they’re unable to negotiate near where I live? Should we charge victims of natural disasters that need assistance after an event? If anything, these kinds of operations create learning opportunities that turn into a race for better technology and stronger, more capable deep sea vessels. I’m all for people calling for help when they need it rather than resorting to denial and covering things up because they’re afraid of going bankrupt. That’s how conspiracies start.
I worked at a dive shop in the PNW for a couple of years. The reckless habits, behaviors, pills and drinking before diving, countless arrogant things. Big egos underwater. “Just be confident and don’t listen to haters”. This is what that mindset leads to.
Niskin bottle is a device that collects a water sample, they didn’t clean it or prepare it to be used, that in itself is a huge communication error or skipped step while rushing
Jeff, Thank you for posting this news so promptly and detailed. You have become one ofy major news sources lately and I appreciate all the work you put into being such a good, factual, dependable channel that I can rely on.
Never clicked that fast on a Titan video - I was waiting for Jeff's next take on this matter since his last one and since we had a few video that came out in June about the next steps in the "Titangate"
It seems to me like everything was just going according to plan, then a sudden and abrupt implosion while Stockton (maybe) was speaking mid-sentence to his passengers about the approach of the Titanic.
@@lemmejustreadthethings speaking to the passengers about the approach is completely speculation. If we are speculating, i think you want it to not be as sad of a story as it is so you want to believe it was an instant death with no warning and talking about the thing they were excited to see
@@o2Hayden Literally.. They drop the weights to slow the descent, its not a wild leap of the imagination for them to go "We will drop the weights to slow our descent" to the passengers, before they would continue with "Because we are approaching the Titanic wreckage" as justification for why they dropped the weights to slow their descent. Ergo: They were approaching the Titanic wreckage. Why must people always have to argue with me over pretty basic things.
Yes i DEF need meters changed to feet yards or miles for me, but we know pretty much where the Titanic is and how far down that was so yep scary deep. I guess i did NOT know or remember that this lil sub was goin to the Titanic. 😿👍🙏⛪🕎✝️🐑🦁🇮🇱

I feel like the last message about dropping weights, happening 6 seconds prior to last ping from the sub (when it imploded) is more related than you think. I think the narrative that they didn’t know what happened is overplayed. Nobody truly knows but that message happening directly before the implosion leads me to believe they suspected trouble and were trying to come back up.
The fake transcript was immediately suspect, because it suggested that the RTM would actually work, which it kinda couldn't because any flaw in the hull big enough for it to detect would cause instant implosion.
So true ! I saw this right from the start. Carbon fiber doesn't give you any warning. Its failure is more like a brutal explosion than a slow expanding metal crack...
Watching the Titan's rate of descent on the screen during the descent. . about 10 meters every couple of seconds. . They were PLUMMETING down at an incredible rate. . They dropped a couple of weights VERY late in the descent. . Still rocketing towards the bottom! I wouldn't like to hit something (even soft ocean mud) at a speed of about 5 meters per second! I wouldn't be surprised if they SLAMMED into the bottom and imploded immediately. . It was a dangerous and ridiculously fragile craft in the first place and a sudden impact would be enough to make it collapse instantly.
One interesting detail that can be deduced from the official last communications with Titan was that there was no mention of any warning alarms from the hull RTMs (Real time monitoring) devices. As I recall, Stockton assured the naysayers that his integrated RTM devices would give sufficient warning of any hull problems, allowing time for them to abort and return to the surface. These RTM devices were the only safety item on board to protect the crew from impending implosion, I always wondered how these devices were tested.
The time between the start of CFRP failure and catastrophic implosion would have been less than a second. The communication system couldn't have even sent a single character in that time, let alone the operator having enough time to explain the problem.
At least it was quick and were unaware of any danger. If there was a concern requiring an immediate accent they’d have texted “XXX”, not “dropping weights”.
@JeffreyEpstein-f6y absolutely. If you are in danger you aren’t going to communicate with anyone not within shouting distance. But if someone with free hands, no job, and a cool enough head did text during an emergency attempt to surface it sure as hell wouldn’t have been “dropping weights”. It’d have been “XXX” if they had nerves of steel, “BAD LEAK HELP” if they didn’t, or just a resigned to their fate “wr fkd”.
@@trader2137 I’m absolutely sure it was at least delaminating and making some pretty disquieting cracking sounds as it went through repeated pressure cycles and the problem grew bigger and louder. The middle of the cylinder would have had the greatest deformation, which would have put an additional angular force onto the carbon fiber at the inflexible titanium ring. If you look at the wreckage the failure seems to have occurred on the top of the titanium ring interface at the bow, shearing the carbon fiber hull along the edge, and blowing it, the dome and view port out relatively clean. Meanwhile the now fractured carbon fiber hull debris exploded into the stern dome, tearing it partially away from the ring as it acted like a cue ball crashing against the tail section, sending it flying.
The total weight of the water on the titans hull was approximately 425,000,000lbs (212500 tons) which is the weight of 470 fully lader boeing 747 airliners. With that in mind it really does blow my mind at how idiotic he was to try and cut corners.
I find it interesting the implosion happened so soon after dropping the weights as well. Maybe they're all related. An unknown physical problem manifests itself as a fault in the software system that controls the weights. Debugging this fault takes up time from the crew, causing delays in response. They finally manage to "reset the system" and think everything's good, because they don't see the error on their screen anymore. But the physical problem is still there. Then when they finally release the weights, some physical component breaks, leading to a catastrophic failure and implosion of the hull. This is all speculation though. I doubt we'll ever know the truth.
@@raakymusic4336 Pure fantasy. It was all fine, then it went bang. That's the best we have from the info we've seen. It fascinates me that people feel the need to inject an invented drama into it.
Maybe but in previous vids there were several times that the Titan lost communication with the vessel above. Those times the Titan was not going to the Titanic but was doing a dive at a different location. I think one time the owner slept overnight in the Titan on the sea floor in a location till communication could be restored. Does anyone remember those previous occurrences?
@@kellyname5733 Well, you could "do your own research", couldn't you? I think what you'll find is that on one or more occasions they had difficulty releasing the drop weights, and so couldn't ascend, but they had a backup system that would release them after some time had passed, but you'll need to check the details, it's out there. There are two key points here. The first is that operation of the Titan was designed to be autonomous, without relying on surface support, and it would be dumb to not ascend just because you've lost comms. The second is that there really is no interaction between what can cause failure of the pressure hull and really anything else. What causes failure of the pressure hull is buckling, a catastrophic process controlled by external pressure and (perhaps not intuitively obvious) the flexibility of the hull material. Every time there is a pressure cycle from a dive, microscopic damage is done to the material, and that reduces its strength and increases flexibility. This process is known as fatigue. At some stage - just as in a game of Russian Roulette - the total amount of damage accumulated means that the buckling threshold is reached, and there is catastrophic buckling, collapse, and implosion. This, or some variant of it, is almost certainly what happened, because there is not much else that could have happened (except dome port failure through fatigue too). This is why they were advised not to build Titan from carbon fibre composite, and why every other DSV is constructed of titanium. Because this failure mode is disconnected from everything, and happens instantaneously and without warnings, the communications log will give no information about the failure. People who don't understand any of this don't seem to do anything to find out, and in fact seem to ignore explanations when they are given. Instead they seem to use every piece of information to construct a fantasy.
Exactly what i thought!!! I only watched one video about rush talking and this is exactly how i feel he would react like. He HATED the coastguards spam 😂😂
rich people believe theyre invincible. when you have no worries of homelessness, sickness, starvation, lack of medical care, going to jail, and can essentially do whatever you like in exchange for a fine that is like pocket change to you, your brain genuinely believes youre invincible. not to the same degree, but you see this a lot in narcissist murderers who ACTUALLY believe if they just give an excuse then theyre off the hook because who wouldnt believe such an innocent sweet person going through hell? they dont realize their lies sound stupid, their testimony sounds stupid, because normal innocent people dont talk like that. They can only approximate what normal people sound like, but because their manipulation has worked outside of courtrooms they believe the judges and officers will be easy to fool just like their past victims. they DO NOT realize or comprehend the danger they put themselves in and what lies ahead if they keep at the path theyre on, because nothing bad has ever happened to them before that they couldnt fix with money, so why would something bad happen now? their brains cant fathom it. what they think, IS their reality. its kind of hard to explain but when you have this mentality youll do anything because in the past you have always gotten away with it. and its a million times worse if the person is rich because the level of stuff they get away with is way higher. narcs usually meet the "end" of their path with legal trouble that they cant bullshit their way out of, but when youre rich youre basically above the law, megacorps have their hands in the government and vice versa, so, to rich people they have actually been invincible. Sadly no amount of money will stop the forces of nature itself when you go into her element. theyre not used to that level of helplessness.
The Titan submersible had drop weights on board as a safety measure to help the vessel return to the surface in case of an emergency. These weights are designed to be jettisoned in the following scenarios: Loss of Power: If the submersible loses power and can no longer actively control its buoyancy or propulsion, dropping the weights would allow it to float back to the surface. Emergency Ascent: In case of any mechanical failure or emergency that requires a quick ascent, releasing the weights increases buoyancy, enabling the submersible to rise to the surface without using its propulsion system. Entanglement: If the sub becomes stuck or entangled, dropping the weights can help free it and allow it to ascend. These drop weights are critical for ensuring the sub's passive ascent, relying on the natural buoyancy of the vessel once the additional mass is removed.
Note that the NTSB takes ~ 18 months for an airplane or train accident report. If this accident had occurred in US waters, they'd be investigating it as well. Government agencies aren't fast. Edit: depth in meters, pressure in PSI. Distinctly American!
NTSB historically superior as far as open communications. NTSB really sets the bar of how truth should be dished out immediately without waiting forever...I hope NTSB can continue being impartial and great communicators...of course final reports take time
Was hoping you would acknowledge this and post about it. I remember commenting a year ago on your other transcript video (which has almost 7M views now) and thought of you right away.
We all know someone who refuses to wear his seat belt in a passenger car. He has faith in the "it's not going to happen to me" mantra. He is often the coolest kid in the room but he is often the least mature. Stockton is that guy.
I saw a video yesterday about that. It’s extremely difficult but not impossible. The engineer explained that if there is a way to find out the computer’s mother board and microchip in acceptable conditions, there is a way to retrieve the data and pictures recorded by the external cameras…but I guess “finding a needle in a haystack” here, is really an understatement; a haystack would be easier.
@@randomami8176 IT person here. Specifically we would need the storage medium they recorded onto. The motherboard and RAM won't give us anything, but the solid state storage drives they were dumping the footage onto can! It depends on where the computer was positioned and where the failure occurred. Imploding at 3200M with the dimensions of the Titan is about equates to about 110lbs of TNT... That's a lot of energy for a giant plastic pill lol. Honestly the water itself would actually be what protects the data in this instance. I kind of doubt the data survived, and even if it did at first it was probably quickly destroyed by the immense pressure sinking down to 3800M without any protection. So it's all entirely possible depending on the type of storage medium, how they recorded and actually offloaded the footage. So long as the actual NAND chips on the storage didn't get shorted out, it's probably there. OH and I did forget that it's possible they had SD cards saving footage onto. That would really have a high chance of recoverability!
@@madezra64 yes, im IT person also. I was kind of curious about why he would mention mother board and ram too…data can only be permanently storage in a HD or SD…thanks for your comment, I will see if I can find that video again and post you the link, see what you think.
Roughly 3000 meters of depth, so let's say 300 bar. Converted to Kilograms per Square Meter, it's roughly 3,059,148.6 kg/m2. Just the cylinder alone (not counting the end domes) had a surface area of around 17.5 square meters (.84m radius x 2.5m long). So that's a total pressure of 53,535,100 kg on that carbon fiber. They were lucky it lasted as many dives as it did!
No one suffered, thats the main thing and it was instantaneous for all of them. So instant in fact, they wouldn't have known anything even happened. It would be like someone switching off a light in a room... scary to think of it like that 🤷♂️
My "outside looking in" observation. The "crew" of the Titan should have never been in control of that submersible or any submersible. Totally unprofessional communication. 1) The Polar Prince didn't know the payload weight before deployment? 2) Not answering questions? 3) Not acknowledging real concerns?

From the way I've heard the implosion described...I honestly wasn't expecting that the submersible was still in that much tact. Interesting.
Bear in mind this is just the external fairing and did not implode. This would have had water on both sides and is just a piece of plastic covering the systems OUTSIDE the pressure vessel. The thing that imploded was the carbon fibre and titanium tube that is, unsurprisingly, not present here so far as I can see.
about the only thing that got destroyed was the carbon fiber which shattered into small shards. the metal such as titanium, aluminum and the acrylic glass are pretty much intact if a little bent. you know the things actual submersibles that deep dive make the pressure vessel out of instead of. fyi pressure vessels to get certified they test them hundreds to thousands of times and they want to have them be in use for say 40-50 years with tens of thousands of dives with humans aboard. The Titan never got certified.

@@ProfessorPesca I just imagined the whole thing to be a crumpled mess.
You didnt understand how it was built then. Exactly what wed expect of a sudden failure is exactly what we saw: whole titanium, and a few tiny pieces of carbon fiber
Does anyone think it’s possible that dropping the weights could have did it? What if when they dropped the weights it caused the titan to pivot or tilt just alittle. And instead of the pressure being distributed through the titan being level and it being evenly distributed. The titan tilted just enough that more pressure was put on one point of the ring and pop. Just like for example.. a glass bottle cap… if you try to pull it off straight on it won’t.. but if you pry and put pressure to one point it bends and pops off… all that glue needed was more pressure on one point than the other.
All I remember is you getting into arguments with commenters who kept trying to tell you it was fake. The argument was that Titan doesn’t use full sentences in their communications, and that this was a solid indicator that it was fake. You resisted heartily despite people telling you otherwise.
Being wrong post-hoc doesn't mean you didn't have a logical position prior. Embarrassing that you think this deeply into it. It's like being smug over a weighted dice roll not ending up on the weighted bias.
I'm not a radio operator, but don't radio and all kinds of other remote communication methods have protocols to actually handle call and response in a better way than this? In this transcript, no one has any idea which message is a response to what, and whether they are repeating themselves because they don't know that they other side received the message while the other side asks another question. This must have happened on every dive, and they never improved it. Or did their text transmissions all have UUIDs and timestamps attached to them so they at least knew which one was which? It seems like they have terrible bandwidth, so I doubt it.
Makes me wonder if dropping the weights damaged the hull integrity. At the depth, is it possible for a weight to not fall away, but come back and hit the bottom of the submersible?
The weights are still going to drop away. The depth isn’t going to make a lead block start floating up. They were going down so quickly they likely dropped the weights to try and slow the decent before they ran into the bottom.
Timestamps in corner appear to be accurate. I don’t know why they wouldn’t be, or why the Coast Guard would have put in a set of timestamps with the accident date and time if they weren’t accurate. And based on timestamp vs depth, they appear to be accurate. Checking depth vs timestamp gives a descent rate somewhat above the 33m/min that the Polar Prince had measured, more like 37m/min. But you’d expect the sub’s descent to accelerate as it got deeper, as the increased pressure compressed the pressure hull, reducing the sub’s buoyancy and thus increasing the net force pulling the sub downward. And it wouldn’t surprise me if the device on the Polar Prince that measured the sub’s depth was off a bit, because there’s a non-zero chance that Stockton Rush either bought the cheapest one on AliExpress or bodged it together out of an old fish finder he had in his garage and a used Atari he found at a yard sale.
If I wasn't told which transcript was the real one, I would have guessed the other one. This transcript feels like a conversation between two teenagers from different schools skipping class due to the weird abbreviations and repeating messages. The other one felt way more formal and was easier to follow along.
Abbreviations and repeating messages are normal proceedure when you expect comms inturruptions. Ask any cop, soldier or sailor. "Messages truncated" indicates that the text messages can be cut off halfway through sending, perfect example of why you'd send abbreviations. Keep the message as short as possible.
They are descending at 43 meters average per minute in the first 1500 meters. By the time they reach 3000 meters they are down to 35 meters per minute. When they imploded, at 3350 meters, they had about 400 meters/14 minutes to go before they began to ease toward the bow of the Titanic. Total time of descent, then, would have been 1 hour 44 minutes or thereabouts.
I'm no expert however having served 8yrs in the R.A.N and 12 yrs in the Australian Army all of their comms seems soo amateurish, and the whole sad affair just a very sad joke.
Text of transcript different, but essentials the same. Only reason to drop wt 1,000+ b4 above sea floor was an out of control dive. From PPs portion of transcript, they noticed problems early; Comms themselves started to fail 30 minutes into the dive (1,700m - already significantly deeper than a normal dive). “Normal,” especially in an underpowered (for speed) battery powered submersible, is to move slowly when in control to maximize battery life. I would take releasing weight before planned ascent as a sign of an emergency. The descent rate was also significantly faster than a normal dive (120ft/min implosion dive vs 82ft/min normal dive). They were either not monitoring telemetry (although PPs “significantly” comment indicates they thought something was wrong with descent rate) and didn’t noticed descent rate, or were attempting to handle the situation but misinforming PP of issue. Depths in transcript show they were not controlling depth pretty much from the beginning, based on depth/elapsed. If nothing else, IMO, this shows a lack of seamanship on the part of the Titan crew (Stockton or Paul-Henri) on many levels; failing to notice the abnormal descent, notifying PP of same immediately and/or beginning emergency recovery immediately when uncontrollable. That led to the implosion more so than any poorly considered design choices - vessel might have been saved if recovery had begun when abnormal descent discovered and uncontrollable, rather than waiting until 3,300 meters. Someone with access to this “master” transcript must have contributed to false one. Except for the Hollywood embellishments, too many specifics on timing and ft/meters were close (if I remember those details correctly).
@@Oops-IMeantToDoThat Tym Catterson explained in his testimony that the weights that were dropped only weighed 35 pounds each. They were only meant to slow the descent.
There is more close up footage released now of what looks like all the CF structure packed into the back end part of the tube with the front portal close by, like as if the portal glass failed and pushed and packed everything to the rear dome, crazy stuff that pressure.
Titan was a cheap (relatively) non-certified vessel. As it wasn’t, there were no requirements for distress beacon, like an aircraft black box, so they probably didn’t install one because of cost (and possible requirements if installed).
Sorry if this has been covered elsewhere, but was there any kind of blackbox or data recorder on the sub? It does make me wonder if there were any sounds or issues during the descent that Stockton ignored.
Huh, that position from the graphic shows them a ways off the stern, but the wreckage was found a ways off from the bow, so they had a chance to maneuver around a bit before the implosion.
Thanks for posting, Jeff!! You didn't mention this, but weren't they still descending too fast? I'm a bit confused about the time of departure. I thought that it was closer to 8:00 a.m. local time. (It has been more than a year since I practically memorized your posts.) However, they do seem to have reached the Titanic ahead of expected descent time. Please comment on that. If true, it doesn't change my conclusions much, even the ones based on the now debunked transcript. I am eagerly awaiting the final report. Again, Thanks!! ❤😊
@@htewing quite congruent indeed… listening to the hearing with the poor Scottish pilot and Rush apparently threw the ps game control at him during a previous dive - charming mood it must have been at oceangate in general 😱
Please don't imply that dropping the weights meant that something was wrong. This was very likely normal practice and we've had more than enough misinformation about this incident over the past year.
one of the people who went and survived of course from a previous trip did say that dropping the weights WAS a part of the operation and it was to slow the decent down and make things go smoother. so we can with some confidence say that this was a normal planned drop and was expected by the mothership. had they been dropping weight for an emergency they would have sent the code XXX which on their sheet was code for immediate ascend to surface.
Of course the mothership not knowing the sub's payload beforehand was also a normal practice so dropping weight without that knowledge was definitely another normal practice. Very professional, you should apply for a supervisor position in OceanGate
as a layperson who is new to this, I took it exactly how he meant it -- that it is part of a normal process, but given how unorthodox everything else they did was, it's worth asking the question of if this was another unorthodox process. it's weird to gripe out a stranger just because you assume people will take him wrong, especially acting like it affects you in any way other than you feeling mildly annoyed in conversations.
At that depth there may be no bubbles. All the air would be instantly compacted into a tiny space and much of it would dissolve into the surrounding water.
@@irri4662 That's the scientific answer. At that depth the air bubbles would compress down, then expand again, then repeat a few times . That's called cavitation. As for the air itself, the gasses would dissolve into the water. The pressure down there is more than capable of it. Think of soda. It's made by dissolving CO2 into water at pressures nowhere near where the Titan imploded.
This scenario would suggest that the Titan descended at a much greater rate than anticipated. That descent rate could only be caused by a greater negative buoyancy than calculated and rigged for. Since this was not the first dive for this vessel, one must conclude that the high rate of descent was not due to an error in calculation or preparation. The interior of the vessel is divided into two compartments: One for the human occupants and below that a smaller compartment housing the batteries and other equipment. Since neither compartment was equipped with sensors for flooding. The most likely cause would be an undetected minor seawater leak into the battery compartment, causing the weight of the vessel to increase to the point that surfacing by jettisoning weights was impossible.
Given the visible level of incompetence in operating the craft, the high rate of descent can certainly have been caused by an error in preparation. For example not weighting the crew before entering the vessel but relying on the weight they claimed to have. Or forgetting some kind of additional equipment on board when the calculations were done. The descent rate was the highest when the descent started. A small leak would have caused an ever increasing descent rate.
@@Itsjustme-Justme they likely increased the rate of decent to increase time on the bottom. i wouldn't be surprised if they were suppose to drop 1 of the weights before they adjusted the direction of their decent between 1000-1200 meters so it would drop away from the titanic and never did it.
Shocking to me how ill prepared this mission seems to have been. Asking for the dive payload? How was this not already known? Saying we don't have a niskin bottle because we didn't clean it. Small thing I guess but speaks to the lack of professionalism of this mission.
They also posted a fake transcript before. Now is the time for all information. Hold nothing back. Yes, airplane accident records include everything even people being scared.
Very happy to see that you've gotten back to covering this now that more info is available. All the shooting conspiracy theory crap was getting old. This scientific/engineering oriented content is what got me into your channel originally. Hope to see more soon!
Great job Jeff!! I wonder if the recovery team ever recovered cell phones (or other cameras) from the 5 men on board?? That would answer whether or not any alarms were going off prior to the mishap. I realize any cameras would be damaged but think of all the information on a TINY SD card these days. I bet at least 1 of 5 men was recording the decent.
@@michaeldonnelly2977 the forces involved mean that any cellphones would be smashed into the tiniest fragments. It’s like having a battleship dropped on your head.

This transcript would give the appearance of a lack of panic onboard Titan. Here one second - into oblivion in the next. That has to be of some comfort to the families... we do know that at the moment of implosion there would be zero time for the passengers' brains to even register destruction. Or so we would all like to think for the sake of the passengers. It seems more likely to me that Stockton Rush did not relate the exact situation inside the submersible to the Polar Prince . Titan does appear to have been descending too fast .. not as fast as initially claimed in the fake transcript - but still too fast. Do we know if it was normal to release the two weights when they did (just prior to implosion)? It just doesn't make sense to release weights unless they needed to ascend... But without any real communications of what was actually happening onboard - this just raises more questions than ever!!!
Did the Coast Guard remove the time stamps on purpose?
Holy crap, this transcript shows there was way more incompetence involved than it was already known.
Consistent with the professionalism of a crew that uses a Playstation controller...
What was incompetent about it?
@@JoeLinux2000 For starters, Why'd the Polar prince not know what the payload was prior to launch? Then no response about the location pinging all over the place. No one was coordinating properly. Once asking for them to write down time and depth, Rush replies with No, i didn't bring/clean the niskin bottle. I could go on...
@@gwcrispi You mean the same controller the US military uses for its multi million dollar drones?
Yes, they did use those controllers.
@@gwcrispi WRONG. MASSIVELY OFF BRAND PLAYstation controller.
There was something definitely wrong when Rush wouldn't communicate clearly. That asshole was still trying to hide that he fucked up.
They were probably begging to go back up and he was probably refusing going on about how adventurous he was. Then the noise started scaring him too and he dropped two weights but it was too late at that point.
It seems to me that comms simply worked badly (often no signal reached PP or signal arrived truncated at TTN) but it was accepted as fact of life (for instance they ask a few times for evologics but then stop for a while).
I think that TTN was completely unaware.
Right when you're being told that your position is changing drastically it is not the time to to say that the instrument that gives your position was NEVER cleaned - I would think that the others on board at that point knew they were screwed
I remember reading a testimony about when one thruster was mounted backward after maintenance; well first the fact they didn't tried the sub before being underwater with paying passengers tells alot, right?
But yeah, one customer said that Stockton struggled with the unfamous controller, and someone else aboard tried to tell Stockton to try something else.
Apparently it tool over one hout until Stockton gave up and handed the controller, and the situation was resolved.
So yeah I wouldn't be surprised to learn that in this dive, the software crashed, Stockton just used his superpowers to ignore the situation until his super willpower solved it, and when nothing happened, PH took control and reset the software and reestablished communications, explaining why he answered at this point.
Chat stopped because a wire leading out the rear ring of the sub was degrading, Stockton handed over the keyboard, he pulled the wire out the computer to reset it, kinda pulled it because he could hardly see, plugged it back in.. thats where the leak started. Final answer I'm calling it right now!
"what is your dive payload" should have been asked like a couple hundred miles beforehand
Yeah really! like how would they know that detail 1000 meters under water off the top of his head? that should have been known before even leaving the PORT!
Wasn't capable of carrying such a massive payload of Stockton Bull shiete
It was a typo.
It’s like a pilot asking about weight and balance questions mid flight
the term 'payload' is not related to ship payload here. It might be data payload and most probably related to the USBL line between the vessel and the ship
The fake transcript looked way more professional than the actual transcript!
All those acronyms felt so pointless like just use your words
because that one was based on what they thought youd like to hear
@@khit007 I was more referring to how unproffessional the actual transcript is. I mean, they sent the same message over and over and over again, yet they didn't bother to answer. But when asked for a comms check, they answered right away.

@@cherrygripe4961 Space is pretty easy for the most part. It's the re-entry that usually gets ya.
@@moviemaker2011z Why do you need to see the Titanic from inside a submarine? You can't get out and walk around so using an unmanned sub with a really good camera seems about the same to me.
5:01 "What is your dive payload". It seems strange to me that the mother ship does not have this info. Isn't this something that should be known to all before the dive even starts? This is a bit like Houston asking a manned space rocket while it is alread in flight, "what is your payload?" Later something similar happens with regards to "the niskin bottle" (whatever that is) TTN replies with "no Niskin, never cleaned....." Again shouldn't this be something the mother ship should have been aware of BEFORE the dive even started? To me this looks like the mother ship and the submersible weren't integrated properly into a functioning unit. And I guess there weren't many checklists either. A suicide mission.
perhaps they noted a faster than normal descent rate at the beginning and wanted to confirm something?
Per Google:
Niskin bottles are used to collect discrete water samples for a range of measurements including pigments, nutrients, plankton, etc.
The open bottle is lowered into the ocean on a wire from a Research Vessel until it reaches a certain depth and then the bottle is closed by a weighted trigger (called a "messenger") that is sent down the cable from the surface.
Niskin bottles are neither cheap nor particularly easy to use.
Also several typos in the messages from PP. All in all it sounds like a badly trained crew.
what happened to 3 strikes safety rule? if anyone sees any 3 things out of the ordinary, they call off the dive?
The suspicion is they carried one Niskin bottle as part of their cover of pretending to be a “research” vessel
“see we took a sample from the bottom, science!”
So they went instantly, no horrific last moments. Since they were so close they were probably all concentrating excitedly on the Titanic coming into view any second and
*CRUNCH*
black screen! - like the Sopranos finale
Actually we don’t know that. Potentially they dropped the weights because something was going wrong and then died 6 seconds later.
Comms failed 1,000ft above sea floor. Impossible for them to see anything outside - and, lights were probably off to save battery as nothing to see.
And they got a up close look so Sad for the 4 passengers.
The third witness. The older gentleman said in his testimony that the final weights that were dropped was a standard procedure that may have been done early to help things go smoothly and that they did not drop enough weight to indicate they needed to resurface.
He said that was a standard weight drop to slow descent.
1,000ft above floor? I could see it a couple of hundred, at most, but not 1,000.
The drop made the structure a little bit swingy and that was enough to atomize it 6 seconds later.
@@Oops-IMeantToDoThat he said that normal would be 100 meters above the floor, but SR most likely dropped weights at 300 meters to ensure that they will slow down gradually, not hit the floor and it will be as comfortably as possible for passengers. With dropping weights at 100 meters there is a chance to hit the floor a bit, which is not a big deal but can be uncomfortable.
Yeah, pretty obvious they were still in descent, as they were 5m deeper at implosion than they were for their final message
@@kreterakete I don’t think the last comms is a good indicator of the exact time of implosion (unless it’s been confirmed by nearby acoustics/sonar arrays.)
This might be considered a hot take, but Rush shouldnt be part of that memoriam. He is the one that caused those deaths, and is one of the rare cases where I will state that Rush deserved what he got, the others on board, did not.
yeah I agree
he deserves to be, his sub still managed to visit Titanic 13 times. Dozens of people had their dreams fulfilled thanks to him. Now his failure is a lesson to other geniuses

Both passengers seemed a little on the husky side. Could their combined weight have contributed to the increased speed of the descent?
@@Davehash Only if their weight surpassed the thrusters' capabilities of lifting them back up. The vehicle being above capacity would indeed increase uncontrolled descent acceleration though, along with making it take longer, if not impossible, to ascend to the surface again.
I've seen a few videos saying about thruster failure, so they could have suffered a failure, descended without control and slammed into the ocean floor if everything else failed. The fact they also let go off of two weights implies a few things.

What are you basing that on? These investigations take a long time to conduct and then even longer to put the presentation together. Believe it or not, it's good that these take a long time because it means they're being thorough. Look at air crash investigations they take years sometimes.
The comms look really confused. Why is Paul-Henri on the comms when he seems unfamiliar with the proceedures? Was Stockton just ignoring the messages? Why is the mothership asking about dive payload halfway through the descent? Why are they asking to deploy a Niskin bottle that was not taken on the sub? Why wouldn't the team on the Polar Prince already know this? Did they just throw out checklists entirely? This is wild.

Coast Guard should back charge Ocean Gate for the costs of this investigation and hearing. Why should my tax dollars go to paying for Rush’s hubris???

The fact that so many resources had to be allocated to search for the submersible makes me think that's a fair point.
The coast guard are paid tax dollars. They don't need more.
Idk man I kinda have to disagree. For one, the money was "already spent" regardless of the titan sub implosion happening or not. It's not like if it hadn't happened, the tax payer would be out less money; the coast guard has a budget, employees, and resources that are already allocated for SAR activities during a given fiscal year.
@@unimoose I completely agree with you. These kinds of operations are called “living in a modern society”. By those people’s logic, should we also charge hikers tens of thousands of dollars when they end up lost and stranded while exploring a national park? Should seniors get charged for rescue and vehicle recovery when they keep continuously drive into the lake surrounding a roundabout that they’re unable to negotiate near where I live? Should we charge victims of natural disasters that need assistance after an event? If anything, these kinds of operations create learning opportunities that turn into a race for better technology and stronger, more capable deep sea vessels.
I’m all for people calling for help when they need it rather than resorting to denial and covering things up because they’re afraid of going bankrupt. That’s how conspiracies start.
I worked at a dive shop in the PNW for a couple of years. The reckless habits, behaviors, pills and drinking before diving, countless arrogant things. Big egos underwater. “Just be confident and don’t listen to haters”. This is what that mindset leads to.
Niskin bottle is a device that collects a water sample, they didn’t clean it or prepare it to be used, that in itself is a huge communication error or skipped step while rushing

Never clicked that fast on a Titan video - I was waiting for Jeff's next take on this matter since his last one and since we had a few video that came out in June about the next steps in the "Titangate"
In testimony Monday, it was established that 2 35 lb weights were dropped to slow descent. - Not for an emergency ascent.
It seems to me like everything was just going according to plan, then a sudden and abrupt implosion while Stockton (maybe) was speaking mid-sentence to his passengers about the approach of the Titanic.
@@lemmejustreadthethings speaking to the passengers about the approach is completely speculation. If we are speculating, i think you want it to not be as sad of a story as it is so you want to believe it was an instant death with no warning and talking about the thing they were excited to see
@@o2Hayden Literally.. They drop the weights to slow the descent, its not a wild leap of the imagination for them to go "We will drop the weights to slow our descent" to the passengers, before they would continue with "Because we are approaching the Titanic wreckage" as justification for why they dropped the weights to slow their descent.
Ergo: They were approaching the Titanic wreckage.
Why must people always have to argue with me over pretty basic things.
One would think that in the event of an emergency ascent they might drop ALL weights, not just two.

Thanks for the update Jeff and the actual transcript.
I feel like the last message about dropping weights, happening 6 seconds prior to last ping from the sub (when it imploded) is more related than you think. I think the narrative that they didn’t know what happened is overplayed. Nobody truly knows but that message happening directly before the implosion leads me to believe they suspected trouble and were trying to come back up.
The fake transcript was immediately suspect, because it suggested that the RTM would actually work, which it kinda couldn't because any flaw in the hull big enough for it to detect would cause instant implosion.
So true ! I saw this right from the start. Carbon fiber doesn't give you any warning. Its failure is more like a brutal explosion than a slow expanding metal crack...
Watching the Titan's rate of descent on the screen during the descent. . about 10 meters every couple of seconds. . They were PLUMMETING down at an incredible rate. .
They dropped a couple of weights VERY late in the descent. . Still rocketing towards the bottom!
I wouldn't like to hit something (even soft ocean mud) at a speed of about 5 meters per second!
I wouldn't be surprised if they SLAMMED into the bottom and imploded immediately. . It was a dangerous and ridiculously fragile craft in the first place and a sudden impact would be enough to make it collapse instantly.
One interesting detail that can be deduced from the official last communications with Titan was that there was no mention of any warning alarms from the hull RTMs (Real time monitoring) devices. As I recall, Stockton assured the naysayers that his integrated RTM devices would give sufficient warning of any hull problems, allowing time for them to abort and return to the surface. These RTM devices were the only safety item on board to protect the crew from impending implosion, I always wondered how these devices were tested.
Agree. And given the wonky comms it is possible the system alarmed after coms failed and before implosion.
the guy cut so many corners - do you really believe he even had them if nobody saw them?
everybody in the industry said his system was garbage even if it worked to give you time to respond. by then you would already be dead
The time between the start of CFRP failure and catastrophic implosion would have been less than a second. The communication system couldn't have even sent a single character in that time, let alone the operator having enough time to explain the problem.
As an EE im pretty sure it cant work at all like his first guy said.
Would be nice to compare other logs of the titan on previous expeditions to see if thing like weight drop was abnomal or not
@@Michael-sb8jf according to Tym Catterson it was normal.
At least it was quick and were unaware of any danger. If there was a concern requiring an immediate accent they’d have texted “XXX”, not “dropping weights”.
@JeffreyEpstein-f6y absolutely. If you are in danger you aren’t going to communicate with anyone not within shouting distance.
But if someone with free hands, no job, and a cool enough head did text during an emergency attempt to surface it sure as hell wouldn’t have been “dropping weights”. It’d have been “XXX” if they had nerves of steel, “BAD LEAK HELP” if they didn’t, or just a resigned to their fate “wr fkd”.
some people reported hearing cracking of the hull
@@trader2137 I’m absolutely sure it was at least delaminating and making some pretty disquieting cracking sounds as it went through repeated pressure cycles and the problem grew bigger and louder.
The middle of the cylinder would have had the greatest deformation, which would have put an additional angular force onto the carbon fiber at the inflexible titanium ring.
If you look at the wreckage the failure seems to have occurred on the top of the titanium ring interface at the bow, shearing the carbon fiber hull along the edge, and blowing it, the dome and view port out relatively clean.
Meanwhile the now fractured carbon fiber hull debris exploded into the stern dome, tearing it partially away from the ring as it acted like a cue ball crashing against the tail section, sending it flying.
@@williamstearns7490scott manlys video?
Seems to me communications weren't that great. Having to ask a question SEVEN TIMES is not good!
The total weight of the water on the titans hull was approximately 425,000,000lbs (212500 tons) which is the weight of 470 fully lader boeing 747 airliners. With that in mind it really does blow my mind at how idiotic he was to try and cut corners.
Seems like Titan was preoccupied with something, hence the delays in responding.
I find it interesting the implosion happened so soon after dropping the weights as well. Maybe they're all related. An unknown physical problem manifests itself as a fault in the software system that controls the weights. Debugging this fault takes up time from the crew, causing delays in response. They finally manage to "reset the system" and think everything's good, because they don't see the error on their screen anymore. But the physical problem is still there. Then when they finally release the weights, some physical component breaks, leading to a catastrophic failure and implosion of the hull. This is all speculation though. I doubt we'll ever know the truth.
@@raakymusic4336 Pure fantasy. It was all fine, then it went bang. That's the best we have from the info we've seen. It fascinates me that people feel the need to inject an invented drama into it.
Maybe but in previous vids there were several times that the Titan lost communication with the vessel above. Those times the Titan was not going to the Titanic but was doing a dive at a different location. I think one time the owner slept overnight in the Titan on the sea floor in a location till communication could be restored. Does anyone remember those previous occurrences?
Would be interesting to see communications from past trips, to compare how the response use to be...
@@kellyname5733 Well, you could "do your own research", couldn't you? I think what you'll find is that on one or more occasions they had difficulty releasing the drop weights, and so couldn't ascend, but they had a backup system that would release them after some time had passed, but you'll need to check the details, it's out there.
There are two key points here. The first is that operation of the Titan was designed to be autonomous, without relying on surface support, and it would be dumb to not ascend just because you've lost comms. The second is that there really is no interaction between what can cause failure of the pressure hull and really anything else. What causes failure of the pressure hull is buckling, a catastrophic process controlled by external pressure and (perhaps not intuitively obvious) the flexibility of the hull material. Every time there is a pressure cycle from a dive, microscopic damage is done to the material, and that reduces its strength and increases flexibility. This process is known as fatigue. At some stage - just as in a game of Russian Roulette - the total amount of damage accumulated means that the buckling threshold is reached, and there is catastrophic buckling, collapse, and implosion. This, or some variant of it, is almost certainly what happened, because there is not much else that could have happened (except dome port failure through fatigue too). This is why they were advised not to build Titan from carbon fibre composite, and why every other DSV is constructed of titanium. Because this failure mode is disconnected from everything, and happens instantaneously and without warnings, the communications log will give no information about the failure.
People who don't understand any of this don't seem to do anything to find out, and in fact seem to ignore explanations when they are given. Instead they seem to use every piece of information to construct a fantasy.

Exactly what i thought!!! I only watched one video about rush talking and this is exactly how i feel he would react like. He HATED the coastguards spam 😂😂
Rush totally seemed so committed, he would rather die than admit being wrong
What a Mickey Mouse setup. Why would you even think about getting on this bodge.
rich people believe theyre invincible. when you have no worries of homelessness, sickness, starvation, lack of medical care, going to jail, and can essentially do whatever you like in exchange for a fine that is like pocket change to you, your brain genuinely believes youre invincible.
not to the same degree, but you see this a lot in narcissist murderers who ACTUALLY believe if they just give an excuse then theyre off the hook because who wouldnt believe such an innocent sweet person going through hell? they dont realize their lies sound stupid, their testimony sounds stupid, because normal innocent people dont talk like that. They can only approximate what normal people sound like, but because their manipulation has worked outside of courtrooms they believe the judges and officers will be easy to fool just like their past victims. they DO NOT realize or comprehend the danger they put themselves in and what lies ahead if they keep at the path theyre on, because nothing bad has ever happened to them before that they couldnt fix with money, so why would something bad happen now?
their brains cant fathom it. what they think, IS their reality.
its kind of hard to explain but when you have this mentality youll do anything because in the past you have always gotten away with it. and its a million times worse if the person is rich because the level of stuff they get away with is way higher. narcs usually meet the "end" of their path with legal trouble that they cant bullshit their way out of, but when youre rich youre basically above the law, megacorps have their hands in the government and vice versa, so, to rich people they have actually been invincible.
Sadly no amount of money will stop the forces of nature itself when you go into her element. theyre not used to that level of helplessness.
Whats a _"Bodge?"_
The Titan submersible had drop weights on board as a safety measure to help the vessel return to the surface in case of an emergency. These weights are designed to be jettisoned in the following scenarios:
Loss of Power: If the submersible loses power and can no longer actively control its buoyancy or propulsion, dropping the weights would allow it to float back to the surface.
Emergency Ascent: In case of any mechanical failure or emergency that requires a quick ascent, releasing the weights increases buoyancy, enabling the submersible to rise to the surface without using its propulsion system.
Entanglement: If the sub becomes stuck or entangled, dropping the weights can help free it and allow it to ascend.
These drop weights are critical for ensuring the sub's passive ascent, relying on the natural buoyancy of the vessel once the additional mass is removed.
I received more coherent drunk texts
Note that the NTSB takes ~ 18 months for an airplane or train accident report.
If this accident had occurred in US waters, they'd be investigating it as well.
Government agencies aren't fast.
Edit: depth in meters, pressure in PSI. Distinctly American!
NTSB historically superior as far as open communications. NTSB really sets the bar of how truth should be dished out immediately without waiting forever...I hope NTSB can continue being impartial and great communicators...of course final reports take time
Was hoping you would acknowledge this and post about it. I remember commenting a year ago on your other transcript video (which has almost 7M views now) and thought of you right away.
We all know someone who refuses to wear his seat belt in a passenger car. He has faith in the "it's not going to happen to me" mantra. He is often the coolest kid in the room but he is often the least mature. Stockton is that guy.
Do we know if the external cameras on the Titan were recording during the descent and implosion and if that footage has been retrieved?
I saw a video yesterday about that. It’s extremely difficult but not impossible. The engineer explained that if there is a way to find out the computer’s mother board and microchip in acceptable conditions, there is a way to retrieve the data and pictures recorded by the external cameras…but I guess “finding a needle in a haystack” here, is really an understatement; a haystack would be easier.
@@randomami8176 IT person here. Specifically we would need the storage medium they recorded onto. The motherboard and RAM won't give us anything, but the solid state storage drives they were dumping the footage onto can! It depends on where the computer was positioned and where the failure occurred. Imploding at 3200M with the dimensions of the Titan is about equates to about 110lbs of TNT... That's a lot of energy for a giant plastic pill lol. Honestly the water itself would actually be what protects the data in this instance. I kind of doubt the data survived, and even if it did at first it was probably quickly destroyed by the immense pressure sinking down to 3800M without any protection. So it's all entirely possible depending on the type of storage medium, how they recorded and actually offloaded the footage. So long as the actual NAND chips on the storage didn't get shorted out, it's probably there.
OH and I did forget that it's possible they had SD cards saving footage onto. That would really have a high chance of recoverability!
@@madezra64 yes, im IT person also. I was kind of curious about why he would mention mother board and ram too…data can only be permanently storage in a HD or SD…thanks for your comment, I will see if I can find that video again and post you the link, see what you think.
@@madezra64 Going of his competence, I like to imagine that the camera was being backed up on a floppy disc or HDD
@@MicrowaveOvenVideo I literally feel the same way. I wonder if they rate WD Blues for 3800 meters??
That NDT timezone always messes me up. It is 90 minutes ahead of EDT. Example: 10:30 NDT is 9:00 EDT. (Ignore the timestamp links. Dang TH-cam!)
Roughly 3000 meters of depth, so let's say 300 bar. Converted to Kilograms per Square Meter, it's roughly 3,059,148.6 kg/m2. Just the cylinder alone (not counting the end domes) had a surface area of around 17.5 square meters (.84m radius x 2.5m long). So that's a total pressure of 53,535,100 kg on that carbon fiber. They were lucky it lasted as many dives as it did!
No one suffered, thats the main thing and it was instantaneous for all of them. So instant in fact, they wouldn't have known anything even happened. It would be like someone switching off a light in a room... scary to think of it like that 🤷♂️
Seems like they were going down too fast the way Its come off from the transmission
Really? They didn't animate the implosion? I waited that whole damn time
My "outside looking in" observation. The "crew" of the Titan should have never been in control of that submersible or any submersible. Totally unprofessional communication.
1) The Polar Prince didn't know the payload weight before deployment?
2) Not answering questions?
3) Not acknowledging real concerns?
From the way I've heard the implosion described...I honestly wasn't expecting that the submersible was still in that much tact. Interesting.
Bear in mind this is just the external fairing and did not implode. This would have had water on both sides and is just a piece of plastic covering the systems OUTSIDE the pressure vessel. The thing that imploded was the carbon fibre and titanium tube that is, unsurprisingly, not present here so far as I can see.
That's the tail section which possibly included the titanium end cap or it was an instrument package outside of the passenger compartment.
about the only thing that got destroyed was the carbon fiber which shattered into small shards. the metal such as titanium, aluminum and the acrylic glass are pretty much intact if a little bent. you know the things actual submersibles that deep dive make the pressure vessel out of instead of. fyi pressure vessels to get certified they test them hundreds to thousands of times and they want to have them be in use for say 40-50 years with tens of thousands of dives with humans aboard. The Titan never got certified.
@@ProfessorPesca I just imagined the whole thing to be a crumpled mess.
You didnt understand how it was built then. Exactly what wed expect of a sudden failure is exactly what we saw: whole titanium, and a few tiny pieces of carbon fiber
Does anyone think it’s possible that dropping the weights could have did it? What if when they dropped the weights it caused the titan to pivot or tilt just alittle. And instead of the pressure being distributed through the titan being level and it being evenly distributed. The titan tilted just enough that more pressure was put on one point of the ring and pop. Just like for example.. a glass bottle cap… if you try to pull it off straight on it won’t.. but if you pry and put pressure to one point it bends and pops off… all that glue needed was more pressure on one point than the other.
That's the tail cone. If you watch the entire video you can see the logo on the left side.
Thankyou for the update Jeff
All I remember is you getting into arguments with commenters who kept trying to tell you it was fake. The argument was that Titan doesn’t use full sentences in their communications, and that this was a solid indicator that it was fake. You resisted heartily despite people telling you otherwise.
He been real quiet since this dropped hahaha embarrassing!
lmao I remember this and Im not even subbed. It's so embarrassing the elite are dumber then normies. It really IS luck, not merit ^^;
Didn't he acknowledge in this video that it was fake?
@@relishcakes4525 THIS video, yes. ...finally
Being wrong post-hoc doesn't mean you didn't have a logical position prior. Embarrassing that you think this deeply into it. It's like being smug over a weighted dice roll not ending up on the weighted bias.
Your voice is so relaxing, I honestly think I'd listen to you talk about anything lmao
I'm not a radio operator, but don't radio and all kinds of other remote communication methods have protocols to actually handle call and response in a better way than this? In this transcript, no one has any idea which message is a response to what, and whether they are repeating themselves because they don't know that they other side received the message while the other side asks another question. This must have happened on every dive, and they never improved it. Or did their text transmissions all have UUIDs and timestamps attached to them so they at least knew which one was which? It seems like they have terrible bandwidth, so I doubt it.
Pretty sure they saw something went wrong and wanted to go up, so they dropped the weights.
Was an alarm going off prior to the implosion?
Did they know?
They never indicated from the sub whether there was alarm, so Stockton's patented RTS design obviously failed
Thanks for the update.
Makes me wonder if dropping the weights damaged the hull integrity. At the depth, is it possible for a weight to not fall away, but come back and hit the bottom of the submersible?
The weights are still going to drop away. The depth isn’t going to make a lead block start floating up.
They were going down so quickly they likely dropped the weights to try and slow the decent before they ran into the bottom.
Not possible
Timestamps in corner appear to be accurate. I don’t know why they wouldn’t be, or why the Coast Guard would have put in a set of timestamps with the accident date and time if they weren’t accurate. And based on timestamp vs depth, they appear to be accurate. Checking depth vs timestamp gives a descent rate somewhat above the 33m/min that the Polar Prince had measured, more like 37m/min. But you’d expect the sub’s descent to accelerate as it got deeper, as the increased pressure compressed the pressure hull, reducing the sub’s buoyancy and thus increasing the net force pulling the sub downward. And it wouldn’t surprise me if the device on the Polar Prince that measured the sub’s depth was off a bit, because there’s a non-zero chance that Stockton Rush either bought the cheapest one on AliExpress or bodged it together out of an old fish finder he had in his garage and a used Atari he found at a yard sale.
If I wasn't told which transcript was the real one, I would have guessed the other one. This transcript feels like a conversation between two teenagers from different schools skipping class due to the weird abbreviations and repeating messages. The other one felt way more formal and was easier to follow along.
The other one had lots of drama but was physically unrealistic.
Reality is often more boring that fiction
And that's exactly why it's fake.
Abbreviations and repeating messages are normal proceedure when you expect comms inturruptions. Ask any cop, soldier or sailor. "Messages truncated" indicates that the text messages can be cut off halfway through sending, perfect example of why you'd send abbreviations. Keep the message as short as possible.
nah this one makes way more sense for the job
That communication is worse than stoned college students at 3AM remembering they have a group project due tomorrow morning.
They are descending at 43 meters average per minute in the first 1500 meters. By the time they reach 3000 meters they are down to 35 meters per minute. When they imploded, at 3350 meters, they had about 400 meters/14 minutes to go before they began to ease toward the bow of the Titanic. Total time of descent, then, would have been 1 hour 44 minutes or thereabouts.
I'm no expert however having served 8yrs in the R.A.N and 12 yrs in the Australian Army all of their comms seems soo amateurish, and the whole sad affair just a very sad joke.
Text of transcript different, but essentials the same. Only reason to drop wt 1,000+ b4 above sea floor was an out of control dive. From PPs portion of transcript, they noticed problems early; Comms themselves started to fail 30 minutes into the dive (1,700m - already significantly deeper than a normal dive). “Normal,” especially in an underpowered (for speed) battery powered submersible, is to move slowly when in control to maximize battery life. I would take releasing weight before planned ascent as a sign of an emergency.
The descent rate was also significantly faster than a normal dive (120ft/min implosion dive vs 82ft/min normal dive). They were either not monitoring telemetry (although PPs “significantly” comment indicates they thought something was wrong with descent rate) and didn’t noticed descent rate, or were attempting to handle the situation but misinforming PP of issue. Depths in transcript show they were not controlling depth pretty much from the beginning, based on depth/elapsed.
If nothing else, IMO, this shows a lack of seamanship on the part of the Titan crew (Stockton or Paul-Henri) on many levels; failing to notice the abnormal descent, notifying PP of same immediately and/or beginning emergency recovery immediately when uncontrollable. That led to the implosion more so than any poorly considered design choices - vessel might have been saved if recovery had begun when abnormal descent discovered and uncontrollable, rather than waiting until 3,300 meters.
Someone with access to this “master” transcript must have contributed to false one. Except for the Hollywood embellishments, too many specifics on timing and ft/meters were close (if I remember those details correctly).
@@Oops-IMeantToDoThat Tym Catterson explained in his testimony that the weights that were dropped only weighed 35 pounds each. They were only meant to slow the descent.
the weights were only 35 pounds each not 1000
Please do more videos on Titan. These are profoundly amazing videos of compiled info
Why didn't they just release the transcript immediately. Not like the coast guard had anything to hide
Government efficiency. We're lucky we got it at all.
Sanitization. Same reason as the Epstein list. Gotta make sure nothing that looks too bad gets through to the peasants.
Wow...just wow....
Finally.. and those pictures.. Damn...
There is more close up footage released now of what looks like all the CF structure packed into the back end part of the tube with the front portal close by, like as if the portal glass failed and pushed and packed everything to the rear dome, crazy stuff that pressure.
just uploaded a video on it tonight
@@MayhemCanuck watch the testimony of Tym Catterson. He explains where the failure happened. It wasn’t the portal.
@@wackyvorlon Thanks will do 👍
Great reportJeff - as expected.
Thanks, good job!
What surprised me is that there were no sonar distress beacons capable of withstanding depths that the Titan dove to installed on the vessel.
Titan was a cheap (relatively) non-certified vessel. As it wasn’t, there were no requirements for distress beacon, like an aircraft black box, so they probably didn’t install one because of cost (and possible requirements if installed).
@@Oops-IMeantToDoThat
Rush was such a scumbag. He was a billionaire playing pretend with his million-dollar toys, not a trailblazing scientist.
Would do little good

Yup
the comms alone shows how amateur’s they operate, with all the misspelling and confusion.
Sorry if this has been covered elsewhere, but was there any kind of blackbox or data recorder on the sub?
It does make me wonder if there were any sounds or issues during the descent that Stockton ignored.
Picture says right on it “tail cone”.
1:35 That’s the back end of Titan. Since it had no air in it it survived the pressure pretty good.
They seemed very unprofessional for engaging in such a dangerous activity.
Huh, that position from the graphic shows them a ways off the stern, but the wreckage was found a ways off from the bow, so they had a chance to maneuver around a bit before the implosion.
Thanks for posting, Jeff!! You didn't mention this, but weren't they still descending too fast? I'm a bit confused about the time of departure. I thought that it was closer to 8:00 a.m. local time. (It has been more than a year since I practically memorized your posts.) However, they do seem to have reached the Titanic ahead of expected descent time. Please comment on that. If true, it doesn't change my conclusions much, even the ones based on the now debunked transcript. I am eagerly awaiting the final report. Again, Thanks!! ❤😊
Great work again Jeff 👏🏻
ThankYou 🙏

@@karin-with-an-i it’d be well in line with this though!
@@htewing quite congruent indeed… listening to the hearing with the poor Scottish pilot and Rush apparently threw the ps game control at him during a previous dive - charming mood it must have been at oceangate in general 😱
Please don't imply that dropping the weights meant that something was wrong. This was very likely normal practice and we've had more than enough misinformation about this incident over the past year.
I said it could be taken both ways, and many people have been discussing this. But I did say that it was likely to slow the ascent for a soft landing
one of the people who went and survived of course from a previous trip did say that dropping the weights WAS a part of the operation and it was to slow the decent down and make things go smoother. so we can with some confidence say that this was a normal planned drop and was expected by the mothership. had they been dropping weight for an emergency they would have sent the code XXX which on their sheet was code for immediate ascend to surface.
Of course the mothership not knowing the sub's payload beforehand was also a normal practice so dropping weight without that knowledge was definitely another normal practice. Very professional, you should apply for a supervisor position in OceanGate
as a layperson who is new to this, I took it exactly how he meant it -- that it is part of a normal process, but given how unorthodox everything else they did was, it's worth asking the question of if this was another unorthodox process. it's weird to gripe out a stranger just because you assume people will take him wrong, especially acting like it affects you in any way other than you feeling mildly annoyed in conversations.
He was very clear and in correct in what he said. Be quiet @antibrevity
Just out of curiosity, while in the area, did the rescuers take a look at the Titanic, too? They were 1000 feet away.
How long does it take for the air bubbles to come back to the surface 🤔 from that depth???
At that depth there may be no bubbles. All the air would be instantly compacted into a tiny space and much of it would dissolve into the surrounding water.
A little while
@@raakymusic4336 is this a scientific answer or your guess ? Because I'm not sure that's true.
@@irri4662 It would be compressed to about 1/400 of the sub's volume. It seems unlikely any would reach the surface.
@@irri4662 That's the scientific answer. At that depth the air bubbles would compress down, then expand again, then repeat a few times . That's called cavitation. As for the air itself, the gasses would dissolve into the water. The pressure down there is more than capable of it. Think of soda. It's made by dissolving CO2 into water at pressures nowhere near where the Titan imploded.
This is so informative! Great job, fantastic reporting!🌻🌼🐝 Keep it up 🙌
This scenario would suggest that the Titan descended at a much greater rate than anticipated. That descent rate could only be caused by a greater negative buoyancy than calculated and rigged for. Since this was not the first dive for this vessel, one must conclude that the high rate of descent was not due to an error in calculation or preparation. The interior of the vessel is divided into two compartments: One for the human occupants and below that a smaller compartment housing the batteries and other equipment. Since neither compartment was equipped with sensors for flooding. The most likely cause would be an undetected minor seawater leak into the battery compartment, causing the weight of the vessel to increase to the point that surfacing by jettisoning weights was impossible.
Given the visible level of incompetence in operating the craft, the high rate of descent can certainly have been caused by an error in preparation. For example not weighting the crew before entering the vessel but relying on the weight they claimed to have. Or forgetting some kind of additional equipment on board when the calculations were done.
The descent rate was the highest when the descent started. A small leak would have caused an ever increasing descent rate.
@@Itsjustme-Justme they likely increased the rate of decent to increase time on the bottom. i wouldn't be surprised if they were suppose to drop 1 of the weights before they adjusted the direction of their decent between 1000-1200 meters so it would drop away from the titanic and never did it.
I agree...I think some h20 got in and it was doomed...
No
Shocking to me how ill prepared this mission seems to have been. Asking for the dive payload? How was this not already known? Saying we don't have a niskin bottle because we didn't clean it. Small thing I guess but speaks to the lack of professionalism of this mission.
5:50 of course the timing lines up with the time shown. it's an animation and the words are popping up at particular times. no time stamps needed.
The reason he's asking is because they sent 6 messages in like 6 minutes in the animation... Nothing wrong with wanting backup info.
They also posted a fake transcript before. Now is the time for all information. Hold nothing back. Yes, airplane accident records include everything even people being scared.
I think they didn’t slow the descent in time and the impact at the bottom caused it to implode
Incredible insight Jeff 😀👍
Incredible? I aim for "mind-blowing" next time! 😄
Very happy to see that you've gotten back to covering this now that more info is available. All the shooting conspiracy theory crap was getting old. This scientific/engineering oriented content is what got me into your channel originally. Hope to see more soon!
Great job Jeff!! I wonder if the recovery team ever recovered cell phones (or other cameras) from the 5 men on board?? That would answer whether or not any alarms were going off prior to the mishap. I realize any cameras would be damaged but think of all the information on a TINY SD card these days. I bet at least 1 of 5 men was recording the decent.
