   Nope…. Nope… Nope… No… No… N0…

   You could not pay me enough to go down in a sub like that to that depth. Oh hell no!

   The flash seems to represent the spike in temperature, but it doesn’t come until after the body is crushed into its minimum volume. I’ve heard a bunch of speculation about the Titan implosion, and hardly anyone mentions that for the occupants, it’s like being the fuel inside a cylinder of a diesel engine, And Titan was far deeper than required for this to happen.

   The story I once heard of the probable fate of the crew of USS Thresher was pretty horrifying: that she was descending stern first when she imploded at something like 2000 ft, under about 60 atmospheres of pressure. The wall of water rapidly compressed all the air in the sub into the bow with more than a diesel engine’s typical compression ratio, heating it to incandescence, incinerating the crew while crushing them.

   You could calculate the effective compression ratio. Unlike a diesel engine, the compressed volume depends on the state of the gas due to adiabatic compression as pressure equalizes. I expect the wall of water would initially exceed the speed of sound, but as the air temperature goes up and the wall of water slows down, a shock wave would travel ahead of the water.
