Submarine implosion would’ve been ‘like crushing an egg’, says former NATO submarine developer 

Tune to Times.Radio free for the latest live updates 🚨

Better than the alternative , running out of air and suffocating, freezing etc. happen quicker than your can cognitively process so you wouldn’t know it.

Unfortunately for the families there will be very little left of the crew after a implosion even if it happened at where communication was lost it would have been catastrophic and instantaneous, the dynamic forces involved in 100ths of a second enormous. If a human hand made out of solid Polystyrene was in the sub at the time it would of shrink to the size of a small garden pea in less than half a second. Thankfully the crew would have had no idea or felt a thing.

They paid their money and they knew the risks involved. No different to base jumping, cave diving, motor racing etc. Most of the time they’re fine, but every now and then there’s a death. Personal responsibility and due dilligence, folks. Very sad but nobody to blame but themselves. You can’t suggest that billionaires don’t have the means to do some research beforehand.

They turned into fish chum, not left to retrieve

The most intelligent and useful comments were not made by any scientist, but by, of all people, James Cameron. And he said something that I found to be very insightful. Something along the lines of “well, now, we have two vessels lying together, on the bottom of the sea, and for the same reason.“ Hubris.

Instant burial at sea. It's crazy to think that a person can essentially be erased in just milliseconds.

No to be disrespectful of those families affected by this incident- there will not be anything left of the bodies of the crew. Most know that an explosion is an energetig outward burst (rapid expansion) of a gas that is equalizing pressure with its surrounding enviironment. An implosion is very similar, but in reverse. The high pressure differential, which the Titan hull was designed to mitigate, was overcome with force, and the craft caved in under 6000 pounds per square inch. Imagine the weight of 2 midsize cars (3000 lbs each) on top of one another and then concentrated down to a 1" x 1" square. That's the force of the environment against the hull of the ship as it raced inward during catastrophic failure. The pressure at 12,500 feet under water is roughly 400 times the load the human body is used to dealing with at sea level. In addition to the mechanical effects of the implosion on a human body, there's the effects of rapid depressurization internally. The people will not be found in any outwardly recognizable form, but DNA and dental record analysis can prove who was on board, but we already know that information. My condolences to the families and friends of these brave adventurers. They did live life while they were here in a way few of us will.

It’s hard to imagine that there’s nothing left of a human body after being exposed to these pressures. I can’t help but wonder what these bodies look like now. It’s both interesting, yet very scary to think about it. Rest In Peace!!

This incident needs to be remembered when Elon Musk is selling tickets to Mars on his flying/exploding grain silo (sharship)

This dude broke all the rules, did not meet industry standards to be innovative, and paid the price. Sad that he jeopardized so many lives being selfish and unprofessional

About a million times more violent than crushing an egg. So violent that it took out the transponder, which was in it's own pressure vessel.

Deceased don't exist any more, I'm afraid. An implosion like that would turn them to mush.

Submarine veteran from the late 70's. Fast Attack out of Pearl. You couldn't pay me 250,000 to go down 2 miles. Man that's creepy!

I'm 54 and my wife and I are VERY worried about our future, gas and food prices rising daily. We have had our savings dwindle with the cost of living into the stratosphere, and we are finding it impossible to replace them. We can get by, but can't seem to get ahead. My condolences to anyone retiring in this crisis, 30 years nonstop just for a crooked system to take all you worked for.

Instant death is preferable to waiting 90 hours to suffocate. RIP.

"Unrecognizable"? I suspect the bodies no longer exist.

The Trieste bathyscaphe set the world record crewed dive in 1960, over 30 000 feet at the bottom of the Marianas trench. It was used for a decade without failure. 63 years ago.

There is no bodies to recover, the 5 occupants didn't feel a thing...the families are the ones that will forever be in emotional pain...RIP

Nothing left of the bodies to recover at that depth sadly for the families

They don't bring the dead down from Everest either.

all the media asking about recovering bodies surely must know what 'catastrophic incident' means. they didn't just float out of it.

Its so tragic that like the Titanic this could have been prevented but the designers of the vessel decided to ignore safety. It is a grotesque irony of history repeating itself.

On the positive side, the company head, the man that didn't want safety testing, was in the sub. Karma.

Stockton Rush wanted to be remembered as an innovator. He will go down in history as a cost-cutting, corner cutting, anti-reality, killer

This is a very sad tragedy and my heart goes out to these people's close friends and family! They're are obviously valuable lessons to be learnt from this tragedy

What kind of father would allow their son on board something dangerous like this He isnt old enough to drink but somehow they were okay with him getting on a sub

Crazy how much rich millionaires and billionaires get coverage over poor people when they die🤦‍♂️

At over 5000 P.S.I. the bodies would have been crushed flat. That and the fact that they are now floating food eliminates any recovery

The sea is a greater risk than anyone thinks

Being crushed like an egg is what everyone who likes to gamble with their life for fun and adventure deserves.

As a form of closure I can see the families of those who perished, charter a ship to the area and hold a memorial service consistent with a burial at sea. RIP.

5 people died in that incident, endless coverage about them everywhere, interviews with their families, etc... etc... at least 500 people died last week in that incident in the Greek seas where the fishing boat carrying migrants capsized, not a pip about that anymore and the circumstances of those 500 deaths are very dodgy, with the Greek authorities caught lying, not as clear cut as the sub implosion clearly some lives matter and some don't

I wonder..the journlists who asked at the coast guard press conference if the bodies will be recovered…did they not get a single lesson in physics?

That submersible was the equivalent of building a car in a garage with cheap brakes, thin metal, no seatbelts, and a faulty GPS.

people dont realise this for some reason.. when the hull implodes your body is crushed and cut up in to pieces.... your talking about looking for parts of the main hull and bits of bodies on the ocean bed in the pitch black!!!!!!!!!! there may be no bodies to find.... the parts would of floated about and spread out over a wide area

I totally respect this expert’s opinion. Great overview of what happened

Carbon wrapped septic tank….what would you expect.

It wasn't a catastrophic loss of pressure, if anything it was a catastrophic gain in pressure.

Its called the "Cruel Sea" by old Seafarers for a reason.

I'd like to see the interviewer pay attention to the answer.

The creatures would be consuming the remains from when it occurred. As time goes by it will be just personal items recovered.........

Catastrophic loss of pressure... don't you mean catastrophic increase of pressure?

An Implosion happens so fast, I'm sure they didn't feel a thing.

Sad :( At 3,800 meters depth, the pressure per square inch is 5,532.42 lbs or 2.76621 tons or 1 smallish elephant moving rapidly (excuse the mixed measurement systems). No suffering. No "recoverables".

Pretty cool that certain fish and other sea creatures can live that far down.

If this were a mission in search of a higher goal, I may have some sympathy for those on board. As it was a vanity project, I view it similarly to an unqualified "mountaineer" paying a guide company to help them reach the summit of Everest... unnecessary, and perhaps endangering the lives of others.

Sad....but they should've known better. Being in a Bluetooth Propelled ROV with two small propellers in the open ocean is insanity. Taking passengers to cover expenses at that. So he was trying to cover his costs......

This is a tragedy, especially for their families. It is also pretty messed up about our world that five millionaires get 24/7 coverage but the boat that capsized near Greece killing 500 poor people received coverage for less than a day.

It's been four days. What fragmentary human remains (if any) there may have been from such a catastrophic implosion are as we speak being rapidly being consumed by the community of scavenging organisms on the sea floor. There's not a lot to eat down there, so this is not something that is going to lie around for any length of time.

Leave those 5 in their resting place. They paid a lot of money to go there. Why keep risking those that didn't choose to go down there....rest in eternal peace.

Absolutely, I'm still confused to the reporter still asking about body recovery

Nope, it would be like a pressure cooker exploding and everything inside turned to goop😮

Condolences to the families. Just so heartbreaking

If they were not going to be found alive, sadly this is probably the best outcome.

spent a number of years as a US Navy submarine sailor, I can attest to the concerns and information of this gentleman.

Human bodies don’t exist under that level of pressure.

The Captain of the Titanic pushed his luck by racing to New York... There were wages put up to see how fast he could make it to New York. Thru his negligence everyone ended up in a watery grave. The manufacturers of this submersible not really a submarine was build by cutting corners. How strange both have ended up in a watery grave...Cos, at 13,000feet in the Ocean. There's not much chance of rescuing the crew...How sad indeed. Man always thinks he is greater or better than nature, as nature always wins in the end...?

The Titanic has eroded so badly, you can’t even tell it’s the Titanic. I know in the 80s when it was first found, it was still recognizable. You could see different artifacts. THAT would be cool to go down and see. The sunken ship is past that now. It’s so badly damaged, It’s a pile of scraps. For me, it’s not worth risking lives to go 2 miles under, just to see scraps. It’s time to let the Titanic rest peacefully.

This lady is so respectful in her questions and responses and is obviously affected by the tragedy. Her behaviour is so far removed from The sensational reporting of many who loose sight of the fact that we are talking about people. Respect also to the interviewee who was also conscious of the need to report on the demise of the people on board with sensitivity. RIP to all who lost their lives and condolences to their families who have to carry this awful burden.

If their is life after death ...i wonder what they would be thinking now ..

Due to the shape of this submersible it collapsed due to integral structure fault. The consistent shape for these deep diving vessels is round, not oval oblong or conical. A sphere compresses the entire craft equally and can manage deeper dives without collapse due to the nature of the structure

just a blob of foaming goo

The pressure at that depth is approx 6000 pounds per square inch. At that pressure.. the bodies would disintegrate.

Lets spend time on the capsizing of the boat and drowning of hundreds of refugees off the Greek coast. These bloody dilettantes were seeking thrills - let’s move on. Tired of this self indulgent plutocracy getting all the ruddy attention

We thank all the hard-working taxpayers for footing the million dollar bill for search and Recovery so the rich boys can play with their toys. Now get back to work.

Don't risk more people's lives to try to recover whats left of the bodies. ROV only. If it can't be done that way (and I can't see how unless they raise the remains of the pressure hull completely). Let them lie where they are.

Nothing to see here folks; this movie ended Sunday night.....at approx. 10,000ft. depth. (1.45hr. elapsed dive time) It was merciful and FAST; the force of the implosion literally blew the legs, rear fairing, and front portal off the sub. The hull damage will be far worse. As for the crew members.....there's nothing to recover; all contents within the craft suffered an "EXPLOSION".

Everything about this expedition screamed "don't do it!"

Lady Titanic Gained 5 more, Prolly paybacks for all the years of pilfering Titanic's dead.....

Can footage from the submersible be retrieved?

Positives.....At least the fish got fed...The Greater Good.....

This is a good example for the Amerikan Economy! Too mach presure!!!!

let this be a lesson, if anything. This is what happens when you scoff at experts.

They literally climbed into their death chamber on Sunday morning.!!!!.What a way for your life to end.😢😢😢

There's nothing to rescue, they would have compressed to the size of an AirPod in milliseconds then combined with the sharks and sea-life over 5 days. RIP... in one with the souls of the Titanic now for good which is pretty ironic.

The wreckage of the Titan submersible will likely become a tourist attraction in it's own right in years to come.

😂 I like how everybody says it's a fragment of a second and they just particlized into magic dust thats absolutely an insult to the intelligent. Working numbers at these pressures and sizes .. it's STILL theoretical. There is five countable body's still inside the submersible. Geez!

I don't know why all the condolences. They paid 250K each and knew the risks.

A fire-piston works by slamming a plunger down with your hand and compressing a small piece of tinder inside a chamber of air. The result is a small burning ember that you can use to make a fire with. Now, instead of hitting a small piston with your hand, imagine dropping a column of water 2 miles high onto a vessel of air that has just shattered like glass - The forces in play are incomprehensible to us surface dwellers. A diesel engine compresses fuel and air together in such a way that it combusts spontaneously without a spark at around 200 bars (atmospheres) of pressure. When the Titan's hull failed it would have collapsed/shattered instantly and its contents compressed together at about 400 bars within the blink of an eye. Much of of the human body is made of water, which I would expect would boil and vapourise under such an immense and abrupt pressure change. A significant proportion is comprised of fats; hydrocarbons, like diesel, which would combust with air under pressure in much the same way. Rather than the egg crushing analogy I would suggest that what happened would be more akin to being inside a hand grenade embedded in concrete - but going Moob! instead of Boom! I'd be surprised if there's much, if any human remains left to recover!

While instant (and it is instant we're talking milliseconds) explosive decompression and implosion is not a "clean" way to go. There wont be bodies to recover sadly.

And remember there are scavengers down there. Any form of carbon and minerals at that depth is an energy source that would not go to waste. We might be able to recover debris, but it's highly unlikely we would recover anything that would be a recognizable body. Or even a recognizable chunk of bone. People don't like thinking about it, I know, but we should be realistic when commiting further resources. It should be labelled a grave site.

The focus the past several days had been on the amount of oxygen the occupants had left and whether rescuers could get to the likely site of the submersible in time. It turns out that authorities had heard something consistent with an implosion around the time the vessel lost communications. So for three days, intended or not, the media had concocted a scenario in which rescuers were racing against time and long odds to rescue what was suggested to be an intact vessel. in the end, that could not have been much further from the truth.

Kursk happened in 2000. This century didn’t start until 2001.

Play dumb games win dumb prizes.

Apparently the Viewport was only rated at 1300m depth and this fact was covered up and the engineer was fired to keep him quiet about it. Why the Owner would go down with the ship makes no sense...

Sad to say, there's probably nothing left of these people down there. Immediate implosion would've shattered their bodies into fragments or perhaps turned them into jelly. What might have been left would've been devoured by the sea life. It's a horrific thought, but it is most likely what happened.

Man must always stick his finger in the fire and see if it's hot! I understand wanting to explore. But this wasn't a scientific expedition. It was a tourist trip! There's only a couple of vehicles that can dive that deep. None are made for rescue. If they had found them same day alive it would not have turned out any different. They had probably the easiest end there is. It would have been so close to instantaneous death that their minds wouldn't have even seen what was coming. A far better death than suffocating or freezing to death. So prayers to the families is all we can do. There are no bodies to recover,maybe a few bones. Everything else will have been turned to paste!

Five dead on a fools mission to a 100 percent unsurvivable environment. One that served no purpose whatsoever except for rich thrill seekers. Well, they're now sharing a watery grave with the heroes of the Titanic who died so women and children could live. "A fool and his money are soon parted." These five are dead proof of that.

Likely d moment of lost contact was when they had catastrophic failure! Rip. Learn from this. Use remote drones for body retrieval. Or let them rest down there. No more human life risk on this adventure. Maybe ban such adventurism ! Leave that specific cemetery alone ! Cursed!

High dollor fish food and not that much

Let's build 1,000 more of those subs. It's a FANTASTIC way to get rid of the wealth class.😁

I won't comment on the idea of using a filament wound carnon fiber/bonded titanium structure as a man carrying pressure vessel, but This event was inevitable over time. Fault propagation in the layers of fibers is a thing and should have been detectable through proper inspection procedures, which apparently weren't done. The loss of integrity would have been instantaneous, causing the sea to implode with force similar to a powerful explosion. There would have been no time for the victims to register the occurence. Heat equivalent to the surface of the sun would have been created for a split second, more than enough time to pronably vaporize the victims. This effect can be seen in slow motion videos of the Mantis shrimp when they strike the shells of mollusks and crustaceans with their spring loaded claws, as a brief flash of very intense light and heat. There would have been no hint of a problem, only sudden nothingness.

The loss of life from military submarines is entirely different than the loss of these 5 joyriders. They had a ticket to ride, a damned expensive one. Military personnel are in to defend their country.

The whole operation was a bodge job. I can see law suites and bankrupcy coming.

I agree with this guy we probably should not risk more lives for a delicate operation. I am a believer in every man coming home but this could potentially end up with another disaster for rescuers sadly.

When OceanGate said they offer the full Titanic experience, they really weren't kidding.

Shame on those who are already posting distasteful jokes about this situation on social media. I don't know how anybody could sink that low.

Terrible news, but imagine if times radio spent as much time covering marine tragedies involving refugees. Maybe the UK would be a little more empathetic and a little less racist.

Unfortunately they'll have been atomised instantly. Heartbreaking.💔💔💔💔💔
