The most frustrating is reading somewhere, I can't remember, that there was some discussion about beacons after having lost comms during an excursion in the past. The conversation apparently didn't get there.

My first proper job in my career was IT for a maritime navigation company. This must have been around 2000, and we were selling these to normal people that have boats. I can't believe they did not integrate EPIRB into something like this triggered by an emergency trigger within the vehicle: https://en.wikipedia.org/wiki/Emergency_position-indicating_...

The facts that even if the unclear "7 ways" to surface in case of emergency, that a) the ship doesn't know where the submersible is located, which GPS would easily solve for and b) if it does manage to use one of these seven ways there's no way to exit the vehicle is absolutely criminal.
