How fast did the people in it die?
Of course once the sub filled with water they would die instantly because it would reach insane pressures (300-400 ATM or 5800 PSI)

To add context here, it takes your brain somewhere around 100ms to detect and then another 250 to process pain. So 4ms is not only fast, it’s absurdly fast.
To get a sense of how fast it is, go ahead and stub your toe, the time it took to feel it is 100 times longer.

I just take solace in the fact that they probably just snapped out of existence instead of having to slowly die in a dark tube over a few days.
