titanic sinking

[Stink Fish Pot]

I was wondering.... I'm sure there were air pockets in the titanic as it went to the bottom.

I wonder how far down a person would live before succumbing to the pressure of the sea. The person would probably die a gruesome, yet instantaneous death when the pressure from the outside pushed into those spaces and crushed the people inside.

Anyone know?

Also, with the airtight sections, would it be possible that there are still human remains deep inside the ship? I'm talking bones, not bodies. I figure the air tight compartments were all compromised at the bottom, but if there were no major holes to allow large fish to scavenge the bodies, bacteria would probably have to do the job. and at that temp and depth, it would be a slow process. Slow enough to still have a femur floating around down there?
