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)

      Wow. So those echoes are literally the sound waves propagating to the surface and reflecting back to the hydrophone on the bottom at 2.62km of depth, a round trip of 5.24km for each echo. That’s also a really great example of how much faster sound propagates in water.
