<p>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.<br clear="none">
