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. .
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.

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.
Well, just from a general design perspective the vehicle’s design for sure got reviewed by some authorities before they were allowed to put it into service. Second, if this thing has been designed for a certain use case at a certain depth, than there’s most probably a solid safety design margin included. Means - this thing can for sure land on the seabed without taking harm. Additionally I just like to put the video in perspective:
The train wagon has been designed for a certain pressure direction (inside>ambient). A submarine is build for the opposite (inside<<ocean). That doesn’t mean, that it can’t implode. It’s just not surprising, that the wagon implodes at 1bar pressure difference.
Incase anyone is wondering… Little clip of an implosion

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:

well That was descriptive, lets see stable diffusion make that image
unless of course there was some creaking and cracking noises first, then maybe a little spray of water.

That deep? I doubt it
Glad they didn’t have to suffer

For others confused like me, this is a clip of some random implosion somewhere else, not the clip of the submersible imploding
