My thoughts on yesterday's accident.

My thoughts were tending in the same direction, Bob. Speculation on the
availability of O2, or the system integrity, is fine, but the first and most
obvious question to me was as to why the airplane was still at altitude.
Job 1, superceding all others, is to get the craft to breathable air. What
was going on? All it takes is one body in the cockpit to initiate the
descent.
