This is usually done with a plug hatch and it's not that complex. The Alvin submersible has one and it's from 1964.

  Exactly. There are so many lessons learned already when designing a device like this there is no point in re-learning them the hard way, just adopt a tried and true design.

    That's what they did? Alvin is an outlier; other bathyscaphes used the (tried-and-true) bolt-in method. Assuming they're out there near the surface bouncing around in 6' waves and whitecaps, what they need isn't a door they can open and drown themselves with. Seems like what they need is a more effective location broadcast. We don't actually know that they don't have good ways of being found. If they do, it makes it all the more likely that the sub is on the bottom :-(
