Their bodies are also pressurized at 1 atms, after being exposed to 400 atms they instantly died. My guess is that they were effectively vaporized/liquified.
Much better way to go then suffocate in darkness.

> Investigation by forensic pathologists determined that Hellevik, being exposed to the highest pressure gradient and in the process of moving to secure the inner door, was forced through the crescent-shaped opening measuring 60 centimetres (24 in) long created by the jammed interior trunk door. With the escaping air and pressure, it included bisection of his thoracoabdominal cavity, which resulted in fragmentation of his body, followed by expulsion of all of the internal organs of his chest and abdomen, except the trachea and a section of small intestine, and of the thoracic spine. These were projected some distance, one section being found 10 metres (30 ft) vertically above the exterior pressure door.
That's with a nine atmosphere pressure differential. The Titanic is at about 400 atmospheres.

> This resulted in the chamber being explosively decompressed from a pressure of nine atmospheres to the one atmosphere of the unsealed chamber system.
Whereas an analogous description of the submarine implosion would describe the opposite, i.e. "explosively compressed from a pressure of one atmosphere to 400 atmospheres."
Imploding or exploding, nine atmospheres is gonna suck. 400 atmospheres is... like standing under a nuclear bomb. The good news is it doesn't hurt, at all.
Someone else on the thread posted a video of a one atmosphere implosion (https://www.youtube.com/watch?v=Zz95_VvTxZM). 400x the pressure here.
This would happen on the order of milliseconds.
Their blood would combust instantly.
They found cooked blood after that accident too.

was 'only' at nine atmospheres the titanic is at four hundred!
400 bar is (from some quick searching) fairly mild for industrial hydraulic systems, and hydraulic fluid doesn’t get especially hot while in use.
On the other hand, a leak in a pressurized hydraulic system is extremely dangerous if you’re around it due to the extreme velocity of ejected fluid.
That said, you can get leaks. I participated on a research cruise with a French submersible, and there was talk of small leaks with the main hatch seal occurring during descent. The "fix" was to go deeper so the pressure would essentially seal the hatch shut.
Part of this is the use of carbon fibre, which is a very brittle material. In bike frame failures, for example, carbon fibre doesn't tend to rip a little or bend, it often fractures greatly or even shatters.
Add the enormous pressure difference, and this is why most people assume instant catastrophic failure.
But if the leak is noticed at say 20m they would have surfaced.
A leak with the amount of pressure at 1000m would cause a high speed jet like from a water cutter. That in turn would cause the material around the leak to be ground away.
This is really bad for the structural integrity and boom the whole thing implodes in a fraction of a second.
I was thinking more like a screw with resistance along the threads such that the pressure goes from 5800 psi to say 20 psi at the last thread or whatever. Then you might get a stable leak.
A screw is there to resist being pulled out. If water got to those screw threads as you posit, that'd basically be like reversing the forces to which that fastener was meant to resist. You go from "big chunk of material to hold in screw" to "little triangular threadforms trying to stay joined to the material around them in spite of 5800 psi trying to transit a pressure gradient insisting otherwise."
I'm not saying it's impossible, I'm just saying if I remotely thought it was possible to end up in that situation, I'd be going back to the drawing board to try to rule out that possibility. My brain just shows me visions of a screw turned into a bullet that barely gets slowed down going through a human body after threadforms crush like tortilla chips, a water cutter blasting through somebody into the opposite ablating a hole and causing a cascaded failure that then shortly thereafter becomes diesel thoomp.
If you'll excuse me, I'm abandoning this train of thought.
