<p>That makes better sense. I was imagining tapped bushings drilled
and glued directly into the hull structure.</p>

<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">
