Now why could they not have attached a small umbilical, a tether to that sub so if something failed that prevented comms or surfacing, or both, to allow it to be found. (I understand the risk of entanglement with something, but even if the line had a low sheer strength, how much would it have cost. And current could have been calculated to ensure tether keep down current from T. wreck.
Also I think I can reliable say that the horror of dying when the oxygen runs out is the waiting for oxygen to run out part. Death from CO2 poisoning is like going to sleep.
I say this with some authority because I have been rushed to hospital and placed in intensive care twice for this exact thing.
