[PSUBS-MAILIST] Titan submersible missing at Titanic site

 Marc,
The head was bolted to a titanium transition ring that was bonded to the carbon fiber cylinder.  There's a video out there somewhere that shows the transition ring being glued to the hull.

I'm curious about the end cap being totally intact (except for the missing viewport). If I remember the other video, the entire end cap is bolted onto the pressure hull  cylinder after the passengers have boarded. End cap titanium, pressure hull laminated carbon fiber reinforced composite. I'm thinking of differences in response to temperature changes and varying external pressure. Could this have been a shear failure separating the entire front assembly from the rest of the hull? I remember an earlier message on this board mentioning scary sounds from the acoustic sensors - strain at the bolted joint? It would be interesting to see what is left of the bolts if they are ever recovered.
