As far as the Concorde is concerned, I'm betting that the designers have
not considered it within the realm of probability of experiencing a
complete loss of cabin pressure at FL650. The Air Force requires all
crew to wear pressure suits above FL500. I don't know how the crew of
the Concorde would initiate and carry through an emergency descent when
suffering with the Bends; maybe the autoflight computer is programmed to
automatically initiate a descent upon a loss of cabin pressure?
