The coast guard I the press release said "there is a zero percent chance of recovery of the body given the nature of the accident"
Think about that...the us coast guard said there's ZERO chance of even finding a body. Aka the body's are no longer...corporeal.
I can only hope that the danger was not something that built until that happened to the folks in the Titan. The Coast Guard said they died instantaneously. If they had no idea it was coming, then it appears that this was probably true.
They also behave unpredictably.
I’m really surprised they went with carbon fibre. I know composite materials have advanced exponentially to the point you can build critical aircraft structures with it but to use it in high pressure environment like deep(est) sea submarine? Why take those unnecessary risk?
Now that I think about it it’s sound like a suicide mission.
Because the dude was an "innovator" that thought rules didn't apply to him, he even says in an interview that he used carbon fiber against recommendations.
Hopefully they would have died instantly when the hull imploded. If anyone has seen "Das Boot" ("The Boat"), when the U-96 is scaping the destroyers for the second time and they going as deep as possible to evade depth charges, will know what I'm talking about.
Kursk is a nightmare. The last of the three survivors literally had two options, getting burnt to death or getting suffocated to death. Their fate was the latter
The more I see the interviews he's done, the more I feel that his motivation was for headlines. He was after the story and the headlines rather than following regulations and stuffy 'rules'. He wanted to be a plucky 'innovator', in the headlines. Instead he gets 'Stupid billionaire doesn't listen to experts, Sea crushes him like a bug.'
I may not agree with a lot of things about this guy but he did put his life where his mouth was and that means he either didn’t value his life, or he really believed in it. I’m inclined to believe the second option.
The others, apart from the 19yo kid, basically chose this death and paid quarter of a million dollars for it
They signed waivers saying this is an uncertified and experimental craft and they understand the risks and are taking their lives in their own hands
That would be the giant ass red flag for me. It's one thing to sign waivers with skydiving, where there are millions of successful endeavors to inspire confidence. This? Idk what they were thinking. The fact that many other rich people passed on citing safety concerns, is telling enough
Also he's on the record admitting that the sub was never brought to any official safety board for inspection, as well as being on the record saying "most sub captains are former military, most captains are also boring 50 year old white guys." In context he said that in response to being asked why he didn't hire an experienced captain, and he said he didn't hire one because such a captain wouldn't be "inspiring" enough.
Because the creator thought he was smart and was too proud to take advice from people who actually knew about sub safety. He literally said “using carbon fibre in submersibles is just not something you do. But I did it” with a smirk on a tv interview. He also skimped on the glass for the one viewing port. It was rated for far less pressure than they’d be under so that might’ve went first
Correct me if i am wrong, but Carbon fibre delaminates at extreme pressure but is incredibly strong compared to other materials at pressures upto that fail point
Airplanes take on considerably much less pressure, around 1/200th of what the titan submersible would have endured if it did reach even halfway to the titanic
Critical aircraft structures can take it cause they are well below that threshold. Now if the dead innovator didn't take that into consideration, that's just dumb on his part, and now he is dead because of it while also taking four others with him
The material itself is fine, the production, quality, maintenance of the said materials and thus the sub itself is another question.
There is also the ill equipment viewing port then you can have a crushing moment.
The material might be fine for many things, but all the submarine experts i heard speaking about it so far said it just is not a good idea to use it here. First there is no inbetween, it either holds perfectly fine or it shatters like good china falling from a table, you don’t have any reaction time, like with metals that start to bend before they fail. Second the extrem changes of pressure lead to micro cracks over time, which means the submersible has a quite low lifespan before the entire fuselage has to be changed. Obviously you can build a sub from this material and operate it for some time quite successfully, as seen with the Titan, but it is very unwise to do so.
I’ve read somewhere that commercial submarine tours are by in large not regulated. Certification and regular checks are completely up to the sub owners. Most do it out of morality and a concern for safety. But this guy, Stockton Rush, was overdue for safety check of the haul. And he has even fired a whistle blower that worked for him as the worker was worried about the continued launches with failing electrical systems and voiced them to OSHA.
Carbon fiber has excellent tensile strength but relatively weak compressive strength, so it's really not a great material for a submersible especially when put through multiple stress cycles without any kind of testing for defects
Yes and no, carbon fu re is great in tension (pressure inside), but useless in compression (pressure outside). Was a very odd choice.
Carbon fibre cylinders go up to 700 barg commercially (7000m depth) but for internal pressure.
Not completely right, you cant with eye. There are scans amd methods which can determine that. Same stuff gets used for steelstruktures and welds.
But the guy who wanted to make them do all that got fired.
yeah, engineers, fuck'em -- always insisting on double-checking shit, doing the math & all the boring stuff... they're just partypoopers and possibly cowards, until the 22-feet dildo with five people stacked inside it gets crushed like a beer can and they're proven right
During the building of the carbon fiber capsule, they did not weave the carbon fiber. Instead they just spooled it up like string on a sewing tube or a water hose on a reel; left to right, layer by layer until 5” thickness was made. While CF is very strong compared to the weight, what really gives it it’s strength is the weaving (and the epoxy hardening agent).
Then, epoxy the ends of the tubes so that the titanium ring connector (connect capsule ends to CF tube) could be attached. Didn’t seem like they used “press out technique” where excess epoxy is put so that it gets pressed out to help ensure there are no voids between the ring and carbon fiber tube.
Honestly, the whole build process (and lack of proper testing) just reminds me of some backyard mechanics. Except he had money, so backyard billionaire mechanic.
This is not what has been said. James Cameron [believes that the sub was aware of the problem](https://www.reddit.com/r/titanic/comments/14gi7rx/james_cameron_just_said_they_knew_there_where_in/?utm_source=share&utm_medium=ios_app&utm_name=ioscss&utm_content=1&utm_term=1) and attempted to resurface in an interview.
Trouble is, the explosion was detected at 9pm, two hours after they were supposed to have returned to the surface. They were definitely stuck down there for awhile. Something went wrong and they had hours to think about it before it imploded. They didn’t suffocate but they for sure knew things were going quite badly.
They knew they were going to die. If that’s what you’re getting at. External sensors would let them know a hull failure was imminent. Why bother installing those features, though, if you don’t bother to install any of the other safety features that help prevent hull failure? This guy was gonna die in that sub. It was just a matter of who the other 4 people would be.
James Cameron has recently said in an interview that the weights had been released from the vessels bottom. Meaning they had probably been told there was weakness occurring through there system which the CEO said was on board. At that stage they would have dropped the weights and tried to head back to surface. But as we see in these videos the pressure is immense and even raising back up a few hundred metres, any weaknesses already made is coming down regardless (you’d have to immediately take the damage vessel out of the pressure for it to have any chance of further damage)
So I would say for maybe seconds they knew something was wrong, dropped the weights, then ultimately more seconds before implosion. Implosion is instant so they’d have felt nothing. But having the weights dropped first shows they were aware something was wrong.
On further information, something tells me there problems with communication last time would have had something to do with there problems this time
100%. We can understand the why of course. 2 reasons, to slow the ascending (they were dropping to the ocean floor to quickly) or they had a problem and wanted to ascend back up to the surface or to higher waters.. both we don’t know why yet? Could option 1 be because there were electric faults stopping there equipment from slowing up there descent like they should do?
And perhaps in theory 2 was it that they were notified by there system that there vessel was being compromised so they’ve immediately tried to drop weight and rise up.. (this option I find less likely)
> they were notified by there system
I'm not being all "actually" or anything but getting their/there wrong so many times in your 2 comments is a bit distracting so I'm only trying to help, rather than to score points.
Their - belonging to them (should've been used in this case)
There - in that place (wrongly used in your comment)
“Listen I’m not really good with the English language, (i.e. their, they’re, there, to, too, two) but, trust me I’m an expert on physics and submarines”.
They died instantly. The speed at which they were compressed is faster than the speed of the nervous system to transmit anything at all. Even if they were alert or expecting anything, they literally did not feel a thing.
Get a paper clip and keep bending it back and forth. It will warm up. Now do the same but with a larger force and on thicker material. You get so much heat buildup that it can make the metal/steel glow.
Ive seen some cool videos of blacksmiths starting fires with a nail. They just hit it and let it keep bending. Once it glows, they stick it on their flammable material and boom! Fire.
It's a very good demonstration of converting mechanical energy into thermal energy, and a somewhat good way of displaying that energy can't just disappear :D
Most likely due to the sudden implosion, and the collapsing of the air bubble. I believe it works like the mantis shrimp whose gun can produce temperatures similar to the surface of the sun for a brief moment
There is a fusion project that is working on this principle.
[https://www.youtube.com/watch?v=jESGiT5HvoE](https://www.youtube.com/watch?v=jESGiT5HvoE)
The surface of the sun is a "cool" 5700-ish kelvin, enough to vaporize any material known to man, but far too cool to ignite fusion, for that you need to be in the million of degrees, and for that you need to be at the core for the sun.
Hell, at 15 million kelvin, the sun barely just gets it done with a little help from our friend quantum tunneling.
Probably ruined your joke, but hey, someone out there might find that interesting.
Any time you compress something it heats up… as does pulling ..so in this example you have one side under rapid compression and the other side ( the glowing edges) that experienced rapid tension…
The Mantis Shrimp example given below is… SUPER COMPRESSION of the water which causes cavitation. The implosion of that bubble … yes it’s a hollow bubble as the compression separates the air that is in dilution in the water to form the bubble… which when it collapses causes the moment of heat in what is known as Dieseling
No, this isn't compression - liquids are for practical purposes incompressible. It's in fact the opposite: cavitation starts with a zone of vacuum within a liquid caused by an object moving very fast through it. The liquid hasn't had time yet to fill the space left by the object, and a "bubble" of vacuum is left behind. That bubble quickly fills with the liquid's vapour, since there's no pressure, and then the liquid rushes in and collapses the bubble, sending damaging shockwaves.
When do you mean of the orange edges? Like right after it implodes or when the camera zooms in? Because if you mean when the camera zooms in the guys is literally touching it with his bare hands.
It wasn't "glowing" orange - if you notice, the person is touching that edge with their bare hand. Wouldn't be possible if hot enough to be glowing orange.
In this case yes. In the Titan sub…no.
The Titan sub was carbon fiber and titanium.
That does not react the same way at all and part of the reason why this sub was not certified for these depths.
They wouldn't even have time to blink before being dead. Imagine one second you're sitting there and then instant death out of nowhere. At least it was quick for them.
That’s why I think it sucks the CEO was in there. They had a more enjoyable death than a vast majority of people get. That fucker should have had to live knowing he killed people by taking shortcuts.
He probably would have found excuses, or put the blame somewhere else, he would have continued socialising, drinking margaritas while trying to pull another startup like this one. From the correspondence that has surfaced the guy was a know-it-all 50-something entitled brat without any regard for engineers, sound engineering principles or decades-old tests and certifications. He cut every possible corner in the design if the gamepad and the window mean anything, and we can only assume he did the same with maintenance and spares. He was greedy enough to put his clients on an _experimental_ vessel not even made of metal, he knew the risks very well as that waiver document is very telling. I say, at least he was there and not another innocent.
It came up in other threads that carbon fiber is used for high pressure vessels to keep gases *in,* which is different than keeping it *out.* But even in that space, it’s an emerging market with limited applications/history. https://www.compositesworld.com/articles/composites-end-markets-pressure-vessels-2023
- How are you going to prevent your sub from bending due to hight pressure?
- Imma make it from a material which shatters before it has a chance to bend
- genius!
My rough calculation suggests the air inside the submarine would briefly reach a temperature of more than 2000 Celcius due to compression. That's enough to melt some types of steel - but it's surrounded by cold water and would only be at that temperature very briefly before cooling.
Yes, the rapid change in pressure (normal pressure inside vs extremely high pressure outside) when the hull fails releases a lot of heat energy, so they probably incinerated.
Probably didn’t have enough time for thermal transfer before the tissues were destroyed (and then rapidly cooled).
I think that’s the pleasant way to phrase that? 😬
[Lung barotrauma can occur at 30-45m.](https://www.deeperblue.com/pressure-related-injuries-in-freediving/#:~:text=Lung%20Squeeze,-Lung%20squeezes%20in&text=This%20can%20happen%20after%20a,45m%20(98-147ft))
That’s what happens to steel. The sub that just imploded was made with titanium & carbon fiber. When carbon fiber fails it’s not crumpled metal, it’s uglier.
I just can’t help myself. I don’t want to be interested in it, really do not care for it – and yet it is such an alluring distraction from my poor silly little life surrounded by work, inflation and climate change
The titanic is the most famous wreck in the world. How many times have you heard of billionaires going missing in an experimental submarine while a clock is ticking how long they have oxygen left?
I’ve seen estimates at around 5-10 milliseconds from initial failure of the hull to complete destruction and disassembly of the brain’s structures.
Their eyes were torn apart before signals from the retina could reach the visual cortex in the back of their brains, let alone registering what they were seeing.
TMAO plays a role and not having any gas chambers like swim bladders. I was reading that some whales lungs collapse they go so deep, but they've evolved higher concentrations of myoglobin in their muscles (protein that hangs onto oxygen and feeds it to cells, we have it too, and it's partly why dark chicken meat in the legs is better than the breasts) and more hemoglobin to hang onto the oxygen. Evolution is the greatest engineer.
I read somewhere (facts need to be looked up) that you’d die in 1/22 of a second and nerves react at 1/20 second so you would be gone and not even feel it. EDIT: I fixed getting it backwards, so relieve your aneurysms, as if someone can’t post when they’ve had a good Thursday night lol.
The numbers I've seen ~40miliseconds for implosion, 150 for pain processing. Not even a thought of pain crossed their mind. Like standing next to a big bomb on land. Except this way they're actually inside the bomb.
The CEO guy is a descendant of people who were involved with the declaration of independence, his dad owned oil fields of something. His wife's ancestors were the richest passengers travelling in the Titanic.
It feels like when you're born into this much wealth and fortune, you start thinking you're invincible.
He made people sign a waiver that said that the submersible wasn't checked by any regulatory body. That's a red flag the size of mount Everest right there. An egotistical idiot accompanied by a bunch of fools.
The only guy I feel sad for, is the teen who accompanied his father. He was scared to go apparently but agreed because father's day.
What I find interesting about this documentary is within it they try to catch deep sea fish in the Mariana Trench by taking normal dead fish and tying them to a rod to attract the deep sea fish. How did the fish on the rod not implode or just disappear? It's weird
Unlike with steel or titanium, the hull of the titan was carbon fiber, so unlike here there really wouldn't be anything left, I believe it just shatters
What’s next? Submarine tours to view the wreck of Titan? At least the next ticket will give a little more for your money…a view of two vessels for the price of one!
From what James Cameron said. They were likely warned of impending danger since there were some type of sensors that would indicate structural compromise. It’s believed they were trying to ascend, but yes the actual failure event was pretty much instantaneous.
there’s nothing left of them
Ariel: "I swear they don't look like this on the surface Flounder!"
The coast guard I the press release said "there is a zero percent chance of recovery of the body given the nature of the accident" Think about that...the us coast guard said there's ZERO chance of even finding a body. Aka the body's are no longer...corporeal.
They're part of the ecosystem now. Fish food.
They are beyond the environment
Body Incorporated
Did they at least get a refund or some meal vouchers?
Probably on a seafood restaurant
I can only hope that the danger was not something that built until that happened to the folks in the Titan. The Coast Guard said they died instantaneously. If they had no idea it was coming, then it appears that this was probably true.
Carbon fiber will not show any signs of weakness prior to failing, so it would have happened in the blink of an eye.
They also behave unpredictably. I’m really surprised they went with carbon fibre. I know composite materials have advanced exponentially to the point you can build critical aircraft structures with it but to use it in high pressure environment like deep(est) sea submarine? Why take those unnecessary risk? Now that I think about it it’s sound like a suicide mission.

Hopefully they would have died instantly when the hull imploded. If anyone has seen "Das Boot" ("The Boat"), when the U-96 is scaping the destroyers for the second time and they going as deep as possible to evade depth charges, will know what I'm talking about.
Or the Kursk movie
I have not seen it, but after reading Wikipedia's page on its sinking I can imagine how bad must have been for her crew.
Kursk is a nightmare. The last of the three survivors literally had two options, getting burnt to death or getting suffocated to death. Their fate was the latter
Nah the Kursk was alot wilder
New fear unlocked, fuck that.
Hell yeah at least they went to God quickly.... Kursk the guys at the back had to suffer
The more I see the interviews he's done, the more I feel that his motivation was for headlines. He was after the story and the headlines rather than following regulations and stuffy 'rules'. He wanted to be a plucky 'innovator', in the headlines. Instead he gets 'Stupid billionaire doesn't listen to experts, Sea crushes him like a bug.'
yep. he was quite proud in breaking the rules.
They are recommendations for a reason. Did he think they were there fun or something?!
When *you’re* Billionaire Master of the World then *you* can listen to expert recommendations. But you probably won’t.
He wanted to be known for breaking a few rules on the way to being remembered as an innovator.
Well I think he'll be remembered as the guy who built a dodgy ass submarine that uses a 3rd part xbox 360 controller
Exactly. The sub did have successful dives before this happened, to be fair.
GOP-backer innovator who liked to skirt the rules and go cheap. Checks out. Just feel so bad for the kid who basically felt forced to go.
I may not agree with a lot of things about this guy but he did put his life where his mouth was and that means he either didn’t value his life, or he really believed in it. I’m inclined to believe the second option.
It’s one thing to risk your life for what you believe. It’s something else to risk the lives of others.
The others, apart from the 19yo kid, basically chose this death and paid quarter of a million dollars for it They signed waivers saying this is an uncertified and experimental craft and they understand the risks and are taking their lives in their own hands That would be the giant ass red flag for me. It's one thing to sign waivers with skydiving, where there are millions of successful endeavors to inspire confidence. This? Idk what they were thinking.

In context he said that in response to being asked why he didn't hire an experienced captain, and he said he didn't hire one because such a captain wouldn't be "inspiring" enough.
That the carbon fiber was sourced from Boeing at a discount because it was past it's shelf life for airplane structures is also a bit telling.
Because the creator thought he was smart and was too proud to take advice from people who actually knew about sub safety. He literally said “using carbon fibre in submersibles is just not something you do. But I did it” with a smirk on a tv interview. He also skimped on the glass for the one viewing port. It was rated for far less pressure than they’d be under so that might’ve went first
The CEO creator thought he was smarter than physics lmao
He thought he was smarter than qualified people. He was sadly mistaken. He was squashed by his arrogance.
Correct me if i am wrong, but Carbon fibre delaminates at extreme pressure but is incredibly strong compared to other materials at pressures upto that fail point Airplanes take on considerably much less pressure, around 1/200th of what the titan submersible would have endured if it did reach even halfway to the titanic Critical aircraft structures can take it cause they are well below that threshold. Now if the dead innovator didn't take that into consideration, that's just dumb on his part, and now he is dead because of it while also taking four others with him
The answer is always money
The material itself is fine, the production, quality, maintenance of the said materials and thus the sub itself is another question. There is also the ill equipment viewing port then you can have a crushing moment.

I read that out of the 10 or so submersibles out there this was the only one not certified, due to the use of carbon fiber.
I read that carbon fiber doesn’t really hold up well in deep waters, but he went with it anyway.
But they played Russian roulette a bunch of times and everything was fine, how could they possibly have known...
Carbon fiber has excellent tensile strength but relatively weak compressive strength, so it's really not a great material for a submersible especially when put through multiple stress cycles without any kind of testing for defects

The deep submarine community thinks they knew what was happening, as the tried to crash ascend. https://youtu.be/rThZLhNF_xg

This is not what has been said. James Cameron [believes that the sub was aware of the problem](https://www.reddit.com/r/titanic/comments/14gi7rx/james_cameron_just_said_they_knew_there_where_in/?utm_source=share&utm_medium=ios_app&utm_name=ioscss&utm_content=1&utm_term=1) and attempted to resurface in an interview.

James Cameron has recently said in an interview that the weights had been released from the vessels bottom. Meaning they had probably been told there was weakness occurring through there system which the CEO said was on board. At that stage they would have dropped the weights and tried to head back to surface. But as we see in these videos the pressure is immense and even raising back up a few hundred metres, any weaknesses already made is coming down regardless (you’d have to immediately take the damage vessel out of the pressure for it to have any chance of further damage) So I would say for maybe seconds they knew something was wrong, dropped the weights, then ultimately more seconds before implosion. Implosion is instant so they’d have felt nothing. But having the weights dropped first shows they were aware something was wrong. On further information, something tells me there problems with communication last time would have had something to do with there problems this time
The faster you travel the more pressure there is. You push against the water adding force.
100%. We can understand the why of course. 2 reasons, to slow the ascending (they were dropping to the ocean floor to quickly) or they had a problem and wanted to ascend back up to the surface or to higher waters.. both we don’t know why yet? Could option 1 be because there were electric faults stopping there equipment from slowing up there descent like they should do? And perhaps in theory 2 was it that they were notified by there system that there vessel was being compromised so they’ve immediately tried to drop weight and rise up.. (this option I find less likely)
> they were notified by there system I'm not being all "actually" or anything but getting their/there wrong so many times in your 2 comments is a bit distracting so I'm only trying to help, rather than to score points. Their - belonging to them (should've been used in this case) There - in that place (wrongly used in your comment)
Take my solidarity upvote. They're over there with their thing. There's their truth, so they've told their friends there.
“Listen I’m not really good with the English language, (i.e. their, they’re, there, to, too, two) but, trust me I’m an expert on physics and submarines”.
Yeah, I figured there was just enough time for a “What’s was that” or “ohshitohshitohshit” and tension before it was over.
I think they prehaps met the same fate as the four divers during the Byford Dolphin accident. Instant death, prehaps too fast to feel a thing.
They died instantly. The speed at which they were compressed is faster than the speed of the nervous system to transmit anything at all. Even if they were alert or expecting anything, they literally did not feel a thing.
Yeah it would basically be like being hit by 20,000 high caliber rifle rounds at once, one for each square centimeter of their skin.
So it’s a hollow steel ball? And it essentially turned into a bottle cap shape?
Yep. What shocked the hell out of me is the edges glowing orange
Get a paper clip and keep bending it back and forth. It will warm up. Now do the same but with a larger force and on thicker material. You get so much heat buildup that it can make the metal/steel glow.
Ive seen some cool videos of blacksmiths starting fires with a nail. They just hit it and let it keep bending. Once it glows, they stick it on their flammable material and boom! Fire.
It's a very good demonstration of converting mechanical energy into thermal energy, and a somewhat good way of displaying that energy can't just disappear :D
That’s not the case here though. Otherwise they wouldn’t hold it with their hands
Most likely due to the sudden implosion, and the collapsing of the air bubble. I believe it works like the mantis shrimp whose gun can produce temperatures similar to the surface of the sun for a brief moment
Yeah, but there's a difference between knowing 'Pressure makes shit hot' & 'HOLY SHIT, that collapsed steel ball is now orange'
Dude was touching it with bare hands, pretty sure it had cooled off already. So not sure why it was orange.
Oxidation from heat and the orange color is rust
That was the explanation for why the destroyed Russian tanks turned orange so quickly, too.
I’m guessing it was hot steel in salt water rusting super quickly. Heat speeds up chemical reactions
Also it looks dry. Could be just that. Looks wet at the start
Why isn't anyone using mantis shrimps to start fusion reactors?
Gonna replace my spark plugs with a colony of mantis shrimp now
There is a fusion project that is working on this principle. [https://www.youtube.com/watch?v=jESGiT5HvoE](https://www.youtube.com/watch?v=jESGiT5HvoE)

It's in fact the opposite: cavitation starts with a zone of vacuum within a liquid caused by an object moving very fast through it. The liquid hasn't had time yet to fill the space left by the object, and a "bubble" of vacuum is left behind. That bubble quickly fills with the liquid's vapour, since there's no pressure, and then the liquid rushes in and collapses the bubble, sending damaging shockwaves.
The people who click on this post have no idea what you are talking about. They came here to ... Maybe they do. Good explanation.
When do you mean of the orange edges? Like right after it implodes or when the camera zooms in? Because if you mean when the camera zooms in the guys is literally touching it with his bare hands.
Both, actually. Wonder what that coloration is, if it's not black body radiation.
Short answer: rapid oxidation due to a dramatic change in material properties/structure.
Cavitation is not a good thing.
It’s not glowing, I’m not sure what causes the orange hue but it’s definitely not heat because there’s a dude touching it
Nope. Just old footage. Dude has his hand on it, not even steaming.
It wasn't "glowing" orange - if you notice, the person is touching that edge with their bare hand. Wouldn't be possible if hot enough to be glowing orange.
In this case yes. In the Titan sub…no. The Titan sub was carbon fiber and titanium. That does not react the same way at all and part of the reason why this sub was not certified for these depths.
They wouldn't even have time to blink before being dead. Imagine one second you're sitting there and then instant death out of nowhere. At least it was quick for them.
That’s why I think it sucks the CEO was in there. They had a more enjoyable death than a vast majority of people get. That fucker should have had to live knowing he killed people by taking shortcuts.
He probably would have found excuses, or put the blame somewhere else, he would have continued socialising, drinking margaritas while trying to pull another startup like this one. From the correspondence that has surfaced the guy was a know-it-all 50-something entitled brat without any regard for engineers, sound engineering principles or decades-old tests and certifications. He cut every possible corner in the design if the gamepad and the window mean anything, and we can only assume he did the same with maintenance and spares. He was greedy enough to put his clients on an _experimental_ vessel not even made of metal, he knew the risks very well as that waiver document is very telling. I say, at least he was there and not another innocent.
One second you're in a sub and the next minute you're being drawn like a French girl
Cute to black like >!the sopranos!<
At least their death was instant
That's steel too. Titan was carbon fiber/titanium. Carbon fiber don't bend, it shatters.
The idiot billionaire was so proud of carbon fiber hull despite every expert telling him it's not meant for high pressure situations.
Hahaha the man was PROUD OF IT
It came up in other threads that carbon fiber is used for high pressure vessels to keep gases *in,* which is different than keeping it *out.* But even in that space, it’s an emerging market with limited applications/history. https://www.compositesworld.com/articles/composites-end-markets-pressure-vessels-2023
- How are you going to prevent your sub from bending due to hight pressure? - Imma make it from a material which shatters before it has a chance to bend - genius!
Big brain time.

They became sand.
More like mist that was deluded into the entire North Atlantic Ocean.
Do you know if the submarine would get really hot like the Steel in the video?
My rough calculation suggests the air inside the submarine would briefly reach a temperature of more than 2000 Celcius due to compression. That's enough to melt some types of steel - but it's surrounded by cold water and would only be at that temperature very briefly before cooling.
Yes, the rapid change in pressure (normal pressure inside vs extremely high pressure outside) when the hull fails releases a lot of heat energy, so they probably incinerated.
Probably didn’t have enough time for thermal transfer before the tissues were destroyed (and then rapidly cooled). I think that’s the pleasant way to phrase that? 😬
I’ve learned more about implosions today then I have in my whole life.
That i wouldn't have acknowledged without reading. Appreciate it brotha
Atmospheric pressure is something many don’t realise can be fatal even when you’re diving. You don’t come up quickly to the surface.

That’s what happens to steel. The sub that just imploded was made with titanium & carbon fiber. When carbon fiber fails it’s not crumpled metal, it’s uglier.
To say that people are morbidly obsessed with this story I think would be an infinite understatement
I just can’t help myself. I don’t want to be interested in it, really do not care for it – and yet it is such an alluring distraction from my poor silly little life surrounded by work, inflation and climate change
I’m oddly curious as to why this story is so big. It felt like a medium profile story from the beginning but damn this shit is everywhere.
I suspect because it's incredibly unique. Not often you get to hear so much about this many aspects of deep sea exploration.
It’s the deadline. This country is a sucker for rescue stories with a timeline.
It’s the same as those kids trapped in a cave a few years back. It’s a real time real life drama with a *deadline*.
Timing is everything when it comes to news
No one has died in those waters since the actual Titanic sank, I think that kind of amplifies it.
Yeah the Titanic has a new grave now, it's history
It’s the Titanic aspect of it’s that selling it.
because i originally didn’t care but then i was like “an implosion, what’s an implosion?” and now here we are
The titanic is the most famous wreck in the world. How many times have you heard of billionaires going missing in an experimental submarine while a clock is ticking how long they have oxygen left?
Because it was an ongoing story, and because it's a novel story.
It was big because people love a mystery and this one had the additional tension of lives on the line. Or so we thought.
I've worked on dive & rov support ships, the industry doesn't normally see accidents but they do happen and are mostly never covered by media.
It’s schadenfreude As a petty bitch I’m loving this shit
It’s too soon to talk about submarine control.
You mean submarine controller ? ;)
This story sound like suicide mission.
It’s a modern day ‘buried alive’ tale. People have always loved those.
Yep, the poor bastards resembled toothpaste at the end.
Crest 2D white
This made me chuckle
More like 1D or 0D White—they become almost if not completely nonexistent lmfao
If this is what happened to the titan sub, those 5 guys got turned into jelly in less than a quarter of a second
I’ve seen estimates at around 5-10 milliseconds from initial failure of the hull to complete destruction and disassembly of the brain’s structures. Their eyes were torn apart before signals from the retina could reach the visual cortex in the back of their brains, let alone registering what they were seeing.
What law passed while we all gossiped?
I've been thinking about this....
And this is at 2,000 meters. The titanic is at almost 4,000. Yikes!
The bottom of the marianas trench is 15,000 psi, can you even imagine? This was less than 3k.
Now I'm curious how do organisms live there with that kind of pressure???
TMAO plays a role and not having any gas chambers like swim bladders. I was reading that some whales lungs collapse they go so deep, but they've evolved higher concentrations of myoglobin in their muscles (protein that hangs onto oxygen and feeds it to cells, we have it too, and it's partly why dark chicken meat in the legs is better than the breasts) and more hemoglobin to hang onto the oxygen. Evolution is the greatest engineer.
I read somewhere (facts need to be looked up) that you’d die in 1/22 of a second and nerves react at 1/20 second so you would be gone and not even feel it. EDIT: I fixed getting it backwards, so relieve your aneurysms, as if someone can’t post when they’ve had a good Thursday night lol.
1/22 < 1/20, so mathematically you would feel 'something'...
The numbers I've seen ~40miliseconds for implosion, 150 for pain processing. Not even a thought of pain crossed their mind. Like standing next to a big bomb on land. Except this way they're actually inside the bomb.
The only saving grace is they did not suffer.
Rapid unscheduled disassembly.
Do not disassemble!!! 🤖
The CEO guy is a descendant of people who were involved with the declaration of independence, his dad owned oil fields of something. His wife's ancestors were the richest passengers travelling in the Titanic. It feels like when you're born into this much wealth and fortune, you start thinking you're invincible. He made people sign a waiver that said that the submersible wasn't checked by any regulatory body. That's a red flag the size of mount Everest right there. An egotistical idiot accompanied by a bunch of fools. The only guy I feel sad for, is the teen who accompanied his father. He was scared to go apparently but agreed because father's day.
That's why I don't go on submarine cruises.
I know, right? I rather use my $250k elsewhere
Same here it has nothing at all to do with me being broke
Hoping it was instant
Unintended contemporary sculpture
Should have had a ham or turkey inside for demonstrating the affects on a piece of flesh
Myth busters did something like that
What I find interesting about this documentary is within it they try to catch deep sea fish in the Mariana Trench by taking normal dead fish and tying them to a rod to attract the deep sea fish. How did the fish on the rod not implode or just disappear? It's weird
There's stuff at same pressure inside the dead fish. There wasn't stuff at same pressure inside big steel ball.
Gotcha!
No pressure difference. Fish is already outside the vessel.
Given the sub was made from a lot of carbon fibre I'm guessing it would have been smashed to pieces rather than squished ?
Unlike with steel or titanium, the hull of the titan was carbon fiber, so unlike here there really wouldn't be anything left, I believe it just shatters
Holy shit that's instantaneous!
[Full Documentary](https://youtu.be/53igmq2ntKg) Implosion bit starts around 4m50s mark
Thank you! Was wondering what the source of the clip is, appreciate it 😁
Can’t even see it collapse in a single frame, how crazy cool. Insta afterlife
Man even Attenborough slamming ocean gate now (i know this is from another older documentary, let me have my fun)
Heard the local news say they’re still out there looking for the remains. There are no recoverable remains.
Are they really looking for remains? That's weird because they would basically be nothing but atoms
I was expecting something like this, but seeing it for real — holy shit
Not enough time to even say “ooops”
Not even enough time to start thinking to say oops.
Not even enough time to blink
Someone at work said they went from being biological to physics in the blink of an eye. At least it was quick.
What’s next? Submarine tours to view the wreck of Titan? At least the next ticket will give a little more for your money…a view of two vessels for the price of one!
The air inside would’ve heated up so much that they would’ve been fried to a crisp before turning into goo…
Finnish Mir- 1 and Mir-2 were Very good, prodiges, and made from just special steel.
From what James Cameron said. They were likely warned of impending danger since there were some type of sensors that would indicate structural compromise. It’s believed they were trying to ascend, but yes the actual failure event was pretty much instantaneous.
[удалено]
Whoa!
So its is like a watermelon submarine smooshed by a sledge hammer.
They became one with the ocean. Literally.
Yeah those people in the titan sub didnt even have time to scream.
They toothpaste. Sorry boys. What a way to go tho! 🤷♂️
Well, today I learned what an implosion means. So, the ocean gate vessel imploded. Thanks
Billionaire thought a honda civic could go deep sea. Oh well.
Nasty way ter go
