If you have ever been to the bottom of a pool and felt the pressure in your ears you can imagine what 10,000 feet may be like. Human don’t belong in the water. Not depths like that. It is insane dangerous. But some of us don’t care about that and we need that danger to feel alive. The only problem I have is the lack of safety. Rest In Peace, guys.
I remember my grandfather telling me that from the start he knew that titanic will sink, he told me that he informed everyone multiple times but no one listened until the security pulled him out of the cinema!
They were 15 mins from reaching the Titanic. I can imagine the amount of water pressure was around them by then. They could probably hear the fibers snapping in the sub as it's shell started to give way the lower they got. They were probably trying to resurface but it was too late.
I wonder if they even realized it was about to implode. Apparently Rush heard the crackling noises on other dives so he might have told them it was normal.
Carbon fiber wasn't a good choice. I'm just a stupid engineer, people much smarter than me worked on this, but man, what a tragedy. Atleast they went quickly. If you're going to die, I'd rather it happen in milliseconds than days.
Just a "friendly question". I am no expert but I watched several videos and read various articles from and by experts that the Titan, being made from predominantly carbon fibre, was not meant to go so deep. Is it not misleading to state it was built to go down 4 000m? The Titan imploded because it could not take the amount of pressure. Clearly not built for those depths?
It had gone down many times before but yes, not all the parts were certified to go that deep but they went that deep anyway. Also carbon fibre delineates and weakens over time due to pressure changes.
1:54 "Titan designed to reach 4,000 metre depth." You should have added "allegedly" or "according to OceanGate" because the viewport of the submersible was only built to a certified pressure of 1,300 meters.
The fact that Oceansgate privately had know that Sunday that the sub imploded immediately after comms and tracking were both lost simultaneously and shared that fact with the Coast Guard,....yet, while deliberately misleading the public for four days is the real tragedy here. The families were hanging on to false hope for days until Thursday when Wood's Hole Oceanographic Institute finally confirmed what was known all along on Sunday by traveling to Titan's last known position and then descending straight to the bottom where Titan's wreckage was found,..exactly where they expected to find it. Authorities knew all along that the sub had imploded on Sunday, and dragged out the story of hope for four days. They only interviewed James Cameron and Robert Ballard till AFTER the fact because both these men already knew early Monday that the sub had imploded. Basically, Stockton Rush designed the sub with a 'tin can and duct tape' mentality which reinforces the sub's design as experimental. Basically, Rush expected this design to be sufficient to sustain a deep sea tourism business using crude and elementary methods on board such as using second-hand gaming technology as a means to control propulsion. Yes, the sub made successful dives to Titanic,.HOWEVER, the carbon fiber shell literally degraded with every trip significantly. This meant that the sub tragically was weakened with every dive. All successful deep sea submersible vehicles utilize a solid component spherical design that needs to meet certification every five years. Stockton 'Crush', if you'll pardon the pun, was using a pawn shop mentality to support a deep sea tourism business using a 'tin can and duct tape' design that received heavy criticism and safety concerns throughout the small deep sea exploration diving community.......and that is the reality of this event.
The Bathyscaphe Trieste had a 5-inch thick steel hull and reached the Mariana Trench in 1960. It weighed 50 long tons. Most of the Trieste had thinner steel, but it wasn’t pressurized. That's already a superior design than the Titan submersible, and the Trieste was made over 70 years ago. When it comes to strength, aluminum alloys have ultimate tensile strengths ranging from 10,000 psi to 75,000 psi. Titanium alloys have ultimate tensile strengths ranging from 25,000 to 220,000 psi. Steel has ultimate tensile strengths ranging from 35,000 to 350,000 psi. There's your winner. Delamination is when layers of carbon fiber begin to unbond due to stress. Steel returns back to its original shape. Damage to carbon fiber remains and accumulates. The material is horrible for a sub. James Cameron designed his Deepsea Challenger sub out of syntactic foam and 2.5-inch steel beams. It was tested for its ability to withstand the required 114 megapascals (16,500 pounds per square inch) of pressure in a pressure chamber at Pennsylvania State University.
@@TheFrenchPug Yeah, it didn't matter. The pressurized point of the Titan submersible hull was surrounded by the carbon fiber. And for a reminder, steel is stronger than titanium, but steel is subject to corrosion and rusting. Non-destructive testing and replacing parts are crucial after every trip. In reality, OceanGate would have saved millions just constructing it out of steel right from the get-go. Both steel and titanium still would have been equally better options than CF, which is a less popular material that quite a few engineers are unwilling to use for expensive, deep-sea diving. It's unproven.
Correct me if I'm wrong but don't all other submersibles have a spherical pressure vessels for the crews? These guys are idiots to think that a cylinder would be able to withstand the pressures.
James Cameron declined a trip in titan. That's all I need to know. He helped design, build and pilot challenger deep at a building cost of approx $37 million. Hes been to titanic 33 times and dove the Mariana trench which is three times deeper than titanic.
And James Cameron is still very much alive. He never said, "Safety is relative." Cameron is a very brilliant, very competent man. Everything Stockton Rush was not.
How was he able to retrieve items from titanic because I read somewhere he found a locked chess. I’m assuming his sub would have dragged it up or something. Not sure how people were able to retrieve anything from titanic since no human could physically dive there.
Your standards are very low. It's informative if you come to the subject knowing absolutely nothing whatsoever about it. There is no analysis - it's just an unquestioning regurgitation of basic information already reported elsewhere. It comes nowhere even close to explaining how it imploded.
CEO Rush would not have lived it out if he didnt go down with these people. He would have probably committed suicide because all of this was because of his negligence. Risk your own life but it's unfair to risk others just because you like to live on the edge and take risks.
Concerning those who like to live on the edge and take risks, are they anxious to see just how far the can go? Or are they OVERanxious to see just how much they can get away with?
Sadly the passengers probably thought they were safe since the ceo was “captain”. If the person who built it trust the vessel enough to dive alongside you assume it’s going to be okay. Like if the CEO of Toyota offered me a ride on the newest flying car i would trust the CEO driving
@@SuperLiar101Its looking like some of the passengers who died had been told of Titans problems from others who rode on it but they decided to take the risk.
He deserved to be crushed with them. He is the reason they met their untimely fate. If he would have never been arrogant and greedy and built a fake sub and charged people $250,000 two-seat using over-the-counter store products to build it they still would be alive to spend their $250,000 in one case $500,000 for the father and son somewhere else.
They didn't habe 96hrs of oxygen. Stockton CLAIMED Titan had 96hrs of oxygen on board but others in the sub community know that figure was for 1 passenger anyway, not 5.
Carbon fiber composites used in a compression load state with high probability of buckling failure are significantly inferior to common AISI 6061 T6xxx aluminum plate and even mild steel. The yield and conservative compression strength of 6061-T651 is around 40-45 ksi, the compression yield of a well laid carbon composite is around 36 ksi. This seeming anomaly for carbon fiber is due mostly to the fiber buckling instability within the composite due to voids, improper lay directions, and delamination from epoxy. The carbon composite is non-isotropic and is subject to unpredictable behavior at stress concentration points under compression. Carbon composites are suited well for tensile loaded applications, such as internally pressurized vessels, but should never be used for externally pressurized vessels without sufficient testing and life-cycle analysis and prediction. A recent paper on composites reviewing these properties may be searched under "A review of the structural factors which control compression in carbon fibres and their composites". I work as a professional mechanical engineer (1982 to present) in both subsea and aerospace environments.
Engineering genius however is no match for management idiocity. See only the ones too incompetent to be engineers and whose only skill is a big mouth and big ego get into management and then boss over the engineers.
I never thought of that, carbon fiber being non isotropic. Makes sense. So it would be difficult to test the ways carbon fiber could withstand the pressure since every area of the material is or could be different? I'm so curious, feel free to elaborate more! Loved what you wrote
@@farahleigh8332 I could only do a simple linear type calculation based on the compression derating values suggested in the paper mentioned. It is worth noting intuitively that the rate of deflection in compression is higher (lower spring rate of the epoxy) versus tension (high spring rate of carbon fiber strands). So you can visualize the carbon to epoxy bond being stressed with every compression cycle, but not so much in tension. Carbon fiber use in aerospace must encounter this, except that it is a mixture of tension and compression cycling and the neutral axis in say a beam application must shift toward the tension side greatly decreasing the compression side loading. Strangely, if the lay of the fibers had been biased longitudinally, say up to 30 degrees off the axis, then the compression strength of the composite would rise radically for this type application. It is not clear how stable that configuration would be in buckling analysis. Carbon composites are for those with deep pockets who can afford high quality R&D. Tourist subs should stick with steel and aluminum.
Im sure the name "TITA.... " Is cursed. Titanic was not the only ship with that name that sank. Before her, many with the name TITA sank. And now this TITAN.

Thank you. Loved the way you explained it. Bravo. They knew the risks, so did the families. If you die doing something you love, then that's the best way to go.
He wanted to please his father, so they say. If his family told the boy, it was safe, well they lied. Does it really matter now why his son agreed to go? They are all dead.
If the titan could withstand underwater pressures ranging 6000 Psi s then it would have never imploded... Another thing... Carbon Fibre Officially the least and probably the worst material ever discovered Another example I still remember apart from the Titan was the Space Shuttle KALPANA CHAWLA and her team was in... It also had this same problem of carbon Fibre causing the accident😢😢😢... Good job team The Quint...
Being able to provide all my needs without the help of the Government is really a dream come through and I’m getting $20,000 returns from my $7,600 investment...
What happened to passenger remaining? When the carbon fiber hull imploded, there would be thousands of bullets that chopped their bodies. The chopped body will become a paste or gel or porridge. After a while, the porridge will dissolve in seawater. Sorry for telling it clinically.
This is not an accurate explanation. Just trying to explain in an imaginable way by most of people. Few people know about the diesel ignition phenomenon.
I would say they died a painless death. Implosion at such depth was caused at microseconds. Nevertheless they died so quickly that their brains couldn’t even register a pain or even feel pain. Ironic but they avoided something slow and worse at the same time. Feels bad for the 19 yo though. His life was just starting.
Imagine forcing your 19 year old son onto a vessel controlled by a Logitech ps4 control not to mention no escape hatch and using carbon fibre wrap not even a solid hull and it wasn’t shaped to disperse pressure.

If they desperate to visit the titanic and pay a fortune why didnt they pay james cameron and rent his sub which is proven over 33 successful trip in even 3 times deeper water
Year 1960. Trieste is a Swiss-designed, Italian-built deep-diving research bathyscaphe which reached a record depth of about 10,911 metres in the Challenger Deep of the Mariana Trench near Guam in the Pacific. On 23 January 1960, Jacques Piccard and US Navy Lieutenant Don Walsh achieved the goal of Project Nekton.
This is a great video and it made me think about the conversations that were being had before they exploded they probably were talking about their money and their wealth and what they were going to do and their cars and then 💥
EVERY ENGINEER THAT IS WORTH THEIR SALT KNOWS THAT YOU DON'T COMBINE COMPOSITE (CARBON FIBRE MONOCOQUE) WITH TITANIUM AND THE PORTHOLE OBSERVATION WINDOW WASN'T CERTIFIED TO DEPTHS OF 4000 METRES PLUS AS WAS THE SUBMERSIBLE. 'CUT & SHUT' ENGINEERING DOESN'T WORK ! ! !😭😭😭😭😭😭😭
Implosion happens when the external pressure is more than the internal pressure, this is what happened but the pressure callouts were incorrect in the video. If the internal pressure is more than the external then that is known as an explosion.
The sub wasn't built properly end of story. And these people unfortunately that paid to go there are tricked into believing this thing was safe and it wasn't, I'm glad the founder was on there he ate his own medicine.
Its a very spooky wreck.They say shoes are all over.Its really a grave.I would only go on a military sub. Titans just a toy.Stockard had far too much ego. Pride killed him.And greed.
For a moment, I thought I was watching one of the videos of Amit Sengupta, since I forgot that I had clicked on a video uploaded by Quint. Nevertheless it was very good!
I am not too sure they didn't feel anything! they must or at least one or two of them heard stg weird, strange, feel some kind of vibrations ?! And probably shared their worries, and try to resurfacing. I think, they realize for about 30 seconds? or more they were in trouble! We will discover it probably in a few months?
When Human insist to challenge God. Titan name means invincible invulnerable. Titanic captain said even God cannot sink this ship. Titan CEO said it’s invulnerable. God shows humanity that he alone has the ultimate power. Sink them both. Subhan Allah God Almighty سبحان الله الجبار
Leave her alone. The fact the sub was found literally right next to her is eerie. It’s like the ghosts of the titanic were angry and decided to sink her. Those who don’t believe in ghosts, I understand but I have witnessed paranormal things I wouldn’t wish on anyone and caught things on camera that are downright terrifying. My psychologist has witnessed things on our video calls that terrified her so I know I’m not crazy. She and I are both believers in the paranormal after witnessing what we have. You may not believe in ghosts, but I guarantee you they are 100% real. Things I can’t explain have been caught on camera and witnessed in person that can’t be medically or scientifically explained away so it’s a possibility the ghosts of the titanic sank that sub 😳 Scientifically everyone’s scientific points on this feed are valid and also a possibility but I’m convinced this could be both paranormal and scientific.
The Titanic should be left alone. Let her RIP. Hopefully all expeditions to view this ship will be called off. This is heartbreaking 💔 worst way to die.
It is one of the best way to die. You are dead in less than half a second. And no, it is not heartbreaking when people die taking extreme risks for fun. What is heartbreaking is say 300 immigrants drowning in the Mediterranean, on their way to a better life.
Not exactly. The sub dove down and was reaching titanic levels when Stockton got a alarm stating bull breach. So they dropped the weights and started acending, and notified the polar prince. Then they lost all contact as the submersible imploded on its acent
We are being lied to . Look at the size of the wreckage pieces that have been recovered , panels still straight , not even crushed , human remains found .Something doesnt add up .
I wish we had something more left from the wreckage for the Coast Guard yo investigate. I understand the implosion happens so quickly they would have felt no pain and even their brains would not have been able to process what just happened but I'm curious if there were signs something was wrong. Maybe they could have heard a loud crack. I hope it truly was quick and they didn't experience fear because of something like that.
Most likely noises coming from structural failure were heard before implosion. It was a slow descent so it weakened over a period of time until it completely imploded like my last relationship
Cyclic fatigue of the controversial material for pressure hulls, Carbon Fiber, also have a cylinder shape didn't help it, should have been a titanium/steel sphere , for 3 people,(not 5) like the other subs before, this thing shattered under pressure , may have got away it the first time going down, but it weakened every use, until it let go
Fun fact they cut corners during manufacturing it should’ve been made of tungsten and not carbon steel as it has nearly double the pressure resistance, and he should’ve hired a professional submersible driver with plenty of experience instead of himself for free play. Stupid games, win, stupid prizes.
Even BBC couldn't explain so well as The Quint has done.
Thank you a lot The Quint!
Glad you liked the video. Thanks.
Thank you for the kind words, parwaz.
the submersible was designed for one way travel.
BBC is trashy
He didn’t explain how instant the death was

Op, on your last sentence, hmmnnn.
Thank you. Loved the way you explained it. Bravo. They knew the risks, so did the families. If you die doing something you love, then that's the best way to go.
Glad you liked the video. Thanks.
Yeah but the kid was kinda forced to go in it tho
He wanted to please his father, so they say. If his family told the boy, it was safe, well they lied. Does it really matter now why his son agreed to go? They are all dead.
@@RA-rv8xo yes 😔😔
If the titan could withstand underwater pressures ranging 6000 Psi s then it would have never imploded...
Another thing...
Carbon Fibre
Officially the least and probably the worst material ever discovered
Another example I still remember apart from the Titan was the Space Shuttle KALPANA CHAWLA and her team was in...
It also had this same problem of carbon Fibre causing the accident😢😢😢...
Good job team The Quint...
Being able to provide all my needs without the help of the Government is really a dream come through and I’m getting $20,000 returns from my $7,600 investment...
I trade with him, The profit are secured and over a 100% return on investment directly sent to you..
Wow!!! I thought I was the only beneficiary of Mr. Philip McCarthy trading services. His technique and strategies are the best.
Went to see history but became history😢😢
What happened to passenger remaining? When the carbon fiber hull imploded, there would be thousands of bullets that chopped their bodies. The chopped body will become a paste or gel or porridge. After a while, the porridge will dissolve in seawater.
Sorry for telling it clinically.
Thanks. I was curious to know
So sad to hear 😢
This is not an accurate explanation. Just trying to explain in an imaginable way by most of people. Few people know about the diesel ignition phenomenon.
I would say they died a painless death. Implosion at such depth was caused at microseconds. Nevertheless they died so quickly that their brains couldn’t even register a pain or even feel pain. Ironic but they avoided something slow and worse at the same time. Feels bad for the 19 yo though. His life was just starting.
Omg that's horrible
supporting this video is a slap in the face to the victims
Imagine forcing your 19 year old son onto a vessel controlled by a Logitech ps4 control not to mention no escape hatch and using carbon fibre wrap not even a solid hull and it wasn’t shaped to disperse pressure.
Especially when your son told you he was terrified and that the tombmiisible was sketchy.
@@TheFrenchPug Funny you reply I’ve got a frug sitting on my arm as we speak 🤣 and yea his father was so irresponsible taking him on board when he had a bad feeling about it.
Idiotic east asian dads are abundant.
@@TheFrenchPug apparently the mother recalls it differently than you do, maybe because Just the media might have made it up based on some quotes by the mother she said so in BBC interview
If they desperate to visit the titanic and pay a fortune why didnt they pay james cameron and rent his sub which is proven over 33 successful trip in even 3 times deeper water
Best information ever related to this tragedy....
Glad you liked the video. Thank you.
Year 1960. Trieste is a Swiss-designed, Italian-built deep-diving research bathyscaphe which reached a record depth of about 10,911 metres in the Challenger Deep of the Mariana Trench near Guam in the Pacific. On 23 January 1960, Jacques Piccard and US Navy Lieutenant Don Walsh achieved the goal of Project Nekton.
This is a great video and it made me think about the conversations that were being had before they exploded they probably were talking about their money and their wealth and what they were going to do and their cars and then 💥
Poor young Suleman he had his whole life ahead of him may they all rest in eternal peace ❤❤❤❤❤❤
EVERY ENGINEER THAT IS WORTH THEIR SALT KNOWS THAT YOU DON'T COMBINE COMPOSITE (CARBON FIBRE MONOCOQUE) WITH TITANIUM AND THE PORTHOLE OBSERVATION WINDOW WASN'T CERTIFIED TO DEPTHS OF 4000 METRES PLUS AS WAS THE SUBMERSIBLE. 'CUT & SHUT' ENGINEERING DOESN'T WORK ! ! !😭😭😭😭😭😭😭
Thanks for good explanation.
Pressure went wrong. Learning physics is hard. 😂
Thank you for explaining it very well.
Cool video
Nice animation work
Good 👍
If your death is written in depth of the ocean. you will rent even a submarine to reach there on time.
~Nick
They were supposed to tour the Titanic, not join them.
The ocean is mysterious, who knows there might be mythical and historical and apex predators that are still alive.
I’m so glad jimmy declined the offer
Titanic- 2 rich people- 0
💀💀💀💀💀💀💀💀💀💀💀💀💀💀
💀 STOCKTON MUSH ! ! ! 💀
💀💀💀💀💀💀💀💀💀💀💀💀💀💀
Thank you come again
Best video explanation so far on this catastrophe...
ONLY A FOOL WOULD IGNORE THE LAWS OF PHYSICS AND ATTEMPT TO CONTROL FORCES THEY DON'T UNDERSTAND ! ! !😭😭😭😭😭😭😭
They thought they would be still alive lmao. I like how some people want a search for the people on board when the pressure already crush them 😂
They need to stop giving him a hard time, he was under alot of pressure.
Condolences to the families affected by this event 🙏
Implosion happens when the external pressure is more than the internal pressure, this is what happened but the pressure callouts were incorrect in the video. If the internal pressure is more than the external then that is known as an explosion.
The sub wasn't built properly end of story. And these people unfortunately that paid to go there are tricked into believing this thing was safe and it wasn't, I'm glad the founder was on there he ate his own medicine.
It's scary how Mrbeast could have also been one of the passengers on the Titan submersible.
Rip to all of the billionaires on the Submarine.
The voyage of the actual RMS Titanic had a higher survival rate than the Titan voyage in 2023.
How fitting, that it just so happens that the last name of the founder and captain of this is Rush...
Its a very spooky wreck.They say shoes are all over.Its really a grave.I would only go on a military sub.
Titans just a toy.Stockard had far too much ego.
Pride killed him.And greed.
Actually stupidity killed him
This is sad because a 17 year old was also on there just to bond with his dad
For a moment, I thought I was watching one of the videos of Amit Sengupta, since I forgot that I had clicked on a video uploaded by Quint. Nevertheless it was very good!
I am not too sure they didn't feel anything! they must or at least one or two of them heard stg weird, strange, feel some kind of vibrations ?! And probably shared their worries, and try to resurfacing. I think, they realize for about 30 seconds? or more they were in trouble! We will discover it probably in a few months?
That ceo Rush guy got a real rush ...of water.🤣
Thanks for video its very informative. Its horrible how the crew fates have ended.
When Human insist to challenge God. Titan name means invincible invulnerable. Titanic captain said even God cannot sink this ship. Titan CEO said it’s invulnerable. God shows humanity that he alone has the ultimate power. Sink them both. Subhan Allah God Almighty سبحان الله الجبار
According to the experts the implosion happened in 1000th of a second, no one would have even realized that they are dead.
If your death is written in the depth of the ocean, you'll rent even a submersible to reach there on time.
They really paid $250,000 for a trip in an underwater pvc pipe that has a flat screen tv and is controlled by a game controller
Leave her alone. The fact the sub was found literally right next to her is eerie. It’s like the ghosts of the titanic were angry and decided to sink her. Those who don’t believe in ghosts, I understand but I have witnessed paranormal things I wouldn’t wish on anyone and caught things on camera that are downright terrifying. My psychologist has witnessed things on our video calls that terrified her so I know I’m not crazy. She and I are both believers in the paranormal after witnessing what we have. You may not believe in ghosts, but I guarantee you they are 100% real. Things I can’t explain have been caught on camera and witnessed in person that can’t be medically or scientifically explained away so it’s a possibility the ghosts of the titanic sank that sub 😳 Scientifically everyone’s scientific points on this feed are valid and also a possibility but I’m convinced this could be both paranormal and scientific.
The CEO overlooked many safety concerns it was never rigorously tested to get certified actually he fired any employee who voiced a concern
There was a dad and a young son on the sub. The son didn’t want to go on and the dad made him.
You sound like a 7-year-old.
The Titanic should be left alone. Let her RIP. Hopefully all expeditions to view this ship will be called off. This is heartbreaking 💔 worst way to die.
Only heartbreaking bcuz of the 19 year old. The other IDIOTS KNEW THE RISKS
Nah. It's still very explorable. Just need a sub with a better camera and much brighter lights.
It is one of the best way to die. You are dead in less than half a second. And no, it is not heartbreaking when people die taking extreme risks for fun. What is heartbreaking is say 300 immigrants drowning in the Mediterranean, on their way to a better life.
Not exactly. The sub dove down and was reaching titanic levels when Stockton got a alarm stating bull breach. So they dropped the weights and started acending, and notified the polar prince. Then they lost all contact as the submersible imploded on its acent
"titan was designed to reach depths of 13,000 feet"
um. no the hell it was not LMAO
The submersible Titan at a depth of 3800 meters has a pressure of 200 tons compressing its hull. 🚨
My issue is media. It had 2 beacons. The mother ship did not call coast guard for 8 hours, and I don’t understand why?
Titan not design for depth sea, very different if compare with Victor Vescapo Submarine.
We are being lied to . Look at the size of the wreckage pieces that have been recovered , panels still straight , not even crushed , human remains found .Something doesnt add up .
This should have been made by NASA scientists not that CEO. He rush too much. How on earth do you have to carry people on board without a test. Am sad
I suspect that since it had already gone down several times they thought it was safe.
Well, his last name was Rush....
These people died fast even they will not find thier bones everthing vanished the pressure there is to much
Liquefied
👍 explained
It was a death trap waiting to happen.
I wish we had something more left from the wreckage for the Coast Guard yo investigate. I understand the implosion happens so quickly they would have felt no pain and even their brains would not have been able to process what just happened but I'm curious if there were signs something was wrong. Maybe they could have heard a loud crack. I hope it truly was quick and they didn't experience fear because of something like that.
Most likely noises coming from structural failure were heard before implosion. It was a slow descent so it weakened over a period of time until it completely imploded like my last relationship
💀💀💀💀💀💀💀💀💀💀💀💀💀💀
💀 WHAT A BLAST ! ! ! 💀
💀💀💀💀💀💀💀💀💀💀💀💀💀💀
Nature,ocean is very scary,don't play with it,always be in your limit,don't cross your limits
Ocean,nature's strong message to all human beings??
When they died,
They liquified, cooked, and extruded out of the cracks in the vessel, in about half a second.
like the scene of the movie Abyss.
Cooked?
@@greenjupiter turned into soup.
@@greenjupiterliterally bcuz you're compressing the oxygen inside maybe?
Wear and tear. It couldn’t handle another trip down there. It was it maracas it was able to go down more than once to begin with.
Cylindrical carbon fiber hull with titanium end caps…not good enough for 10,000 ft + under the ocean.
Nature agreed and they perished.
Good
Title should be "What we were told to believe"
Mabye the stabilization pressure is not working well so the outside pressure is more high than inside pressure .
Nyc stuff
The question should be Why did it implode?! not How did it implode?!
Cyclic fatigue of the controversial material for pressure hulls, Carbon Fiber, also have a cylinder shape didn't help it, should have been a titanium/steel sphere , for 3 people,(not 5) like the other subs before, this thing shattered under pressure , may have got away it the first time going down, but it weakened every use, until it let go
Carbon fiber's strength is its ability to not expand or stretch. It's weakness, as it was applied, withstanding compression.
Crustaceous fatigue, pressurization
Logitech gaming controller should give you a hint.
Fun fact they cut corners during manufacturing it should’ve been made of tungsten and not carbon steel as it has nearly double the pressure resistance, and he should’ve hired a professional submersible driver with plenty of experience instead of himself for free play. Stupid games, win, stupid prizes.
I think I lost my bestbuy gift card while listening to this dude lol
I lost my subway card during this......strange
All those billions...just gone. Just like on the Titanic.
