I saw that Mythbusters show, the diving helmut was filled up with “meat” and “organs”. They also did a railroad tank implosion by creating a vacuum in the railroad tank. Less than a second to crush the tank like a squashed beer can.
These may have been wet sections of the craft, not part of the pressure hull.
Except there is HUGE motivation to diagnose then failure modes of crashed aircraft to improve the safety of future airliners.
There is about zero such economic motivation for deep-sea tourism subs.
If I understand the crush/implosion scenario usually applied to submarine accidents, submarine hulls, being made of steel or titanium, begin to incrementally fail as they fall below crush depth. The sudden inrush of water raises air pressure (through volume reduction) and the crew either immediately passes out/dies, then the hull finishes crushing in as it disintegrates. The spectacular explosive implosion only occurs when a pressurized compartment is not deformed (thereby violating its pressure holding integrity) prior to total failure. Obviously, in a locked down compartmented submarine, you could have both failures happening depending on how the specific vessel’s structure failed.
The Titan was essentially a thick reinforced graphite tube with titanium end caps. IIRC, mention was made of finding the end caps in the debris field during yesterday’s USCG press conference. No information was shared on how damaged they were, if at all. By contrast, graphite fabrications under compression tend to fail suddenly and spectacularly; often turning into tangled shreds. So the “poof and you’re dead” analogy is probably not too wide of the mark.
Speculation now has the loss occurring about the time the communications were severed. That is, around an hour and 45 minutes into the descent. Previous reporting indicated that descent to the bottom took about 2 1/2 hours. So, if the accident occurred as speculated, the vessel was still thousands of feet above the wreck site and the debris would have dropped from that height down to the seafloor. An interesting post-mortem question will be whether the descent sled was deliberately dropped by the crew – indicating they knew they were in trouble and were attempting to resurface - or if it was simply blown/torn off the descending pressure vessel as it came apart.
His arrogant stupidity ended that corner of the tourist industry.

Oh goody another it’s all fake
Exactly
Using what exactly?
So, it would be a matter to energy conversion?
No, it is not. A tank gun has a chamber pressure of 73,950 psi. Metal objects are not compressed very much at all, though they will be reshaped.
Not sure how exactly, but apparently the technology exists:
“To answer the question of why this happened and what could have been done to prevent it, investigators will be gathering every piece of the debris they can find, according to Ryan Ramsey, former submarine captain in Britain’s Royal Navy.”

What could have been done to prevent this was for the full of himself jerk to hire some fifty year old engineers who had knowledge….oh that and do some of that useless safety testing
One doesn’t need debris to figure this out
I don’t disagree with that, but can they recover the debris and should they recover debris are two separate discussions.
I’ve read the implosion (compression stroke) is about 1 millisecond, followed by an explosion after super heating in compression. Human awareness is about 2 milliseconds. No one will ever know if they had awareness or not.
