TITAN

[Jim Blair]

Freda has been watching the news for the latest about that missing sub.  Lots of fluff and redundancy.   But from the little I saw; the answer is almost certain.  It was crushed while being lowered, and is that recently discovered debris.  

The sounds they put so much hope in is unlikely to be any survivor.  Survivors would not be randomly banging on anything; they would be banging SOS (... --- ...) which any sailor would recognize as a distress call. 

Spheres (bathyspheres) have gone deeper many times and survived.  And even that TITAN has done it before. So why was it crushed now?

A sphere is a better (the best!) shape to withstand high pressure.  TITAN's tube shape makes it more subject to being crushed.  And each time it has gone deep, tiny fractures likely formed in its hull.  Like bending a paperclip, each time it remains intact, until it breaks.
