I'm not sold on the crushed soda can analogy for the sub. Doesn't really fit. Metal bends and warps. But that sub is carbon fiber. 4"-5" thick, I read. Carbon fiber shatters like glass. So if that sub suffered a pressure leak, it may have shattered into a million pieces or just broke into a few big pieces like a thick bottle. If something like the front window blew inside, it may have just instantly filled with water and not deformed at all. Sadly, the end result for the passengers is the same no matter how the hull broke.

I think if that CEO hadn't been on board, he'd be facing some serious jail time. Although apparently there was no hiding of that fact that the passengers would be risking death in several different ways. That's not the kind of paperwork you just skim over and sign.

I also read that the hatch was bolted shut from the outside. Not sure if it had a way to vent air from the outside, but if not, they could be bobbing on the surface and still run out of air.
