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)

      It’s also why airplane tires are filled with nitrogen instead of air. On landing, the high pressure and heat can cause the oxygen in air to combust.

        Phew. Imagine being the pilot to find that out.
