RIP to those who parished. I think most can take solace knowing that if it turns out to be true that it was an implosion, it would have been instant, and the occupants likely felt nothing. .

Read over on Reddit that an implosion would have taken 0.029 seconds, while the brain needs 0.150 seconds to register stuff.

Don't quote me on the actual numbers, though.

I think it is from here:

Catastrophic Implosion of a submersible explained:
When a submarine hull collapses, it moves inward at about 1,500 miles per hour - that’s 2,200 feet per second.
The time required for complete collapse is 20 / 2,200 seconds = about 1 millisecond.
A human brain responds instinctually to stimulus at about 25 milliseconds. Human rational response (sense→reason→act) is at best 150 milliseconds.
The air inside a sub has a fairly high concentration of hydrocarbon vapors.
When the hull collapses it behaves like a very large piston on a very large Diesel engine.
The air auto-ignites and an explosion follows the initial rapid implosion. Large blobs of fat (that would be humans) incinerate and are turned to ash and dust quicker than you can blink your eye.

unless of course there was some creaking and cracking noises first, then maybe a little spray of water.

That deep? I doubt it

At that depth, I feel like creaking and cracking is probably common. However, I don't think there would be any spraying as an indicator. Based on this tweet I saw earlier.

Yeah but they had to get to that depth. With the pressure gradually increasing, I don't see why it's not possible for them to hear creaking and groaning as the pressure increased, until they eventually reached fatal depth.

Glad they didn't have to suffer
