re: #21 Targetpractice

I keep coming back to the question of why there was no attempt at an emergency ascent, since such systems are usually designed to be separate from the main power and thus can be activated even if the rest of the submersible is dead as a post. And the only answer that makes any sense is that whatever happened was so fast that the people onboard had no time to react, with the most obvious example being the hull imploding.

Or they ascended and are trapped on the surface, waiting to be found.
