As I mentioned, the Capt. was a highly trained, extremely experienced
ex-military pilot whom had undergone chamber training so no matter
how insidious, he undoubtedly knew how to recognize the telltale
symptoms of hypoxia (e.g: degraded vision, lightheadedness,
discoloration of the fingernails and lips, etc.) AFAIK, it remains a
mystery as to precisely what happened on that incredibly strange day
in 1999.


It is especially strange given that there is an altitude alerter
horn which goes off when the cabin exceeds about 10,000' pressure
altitude (IIRC, one thing the recovered CVR tape showed was that
the warning horn was sounding, confirming that the cabin pressure
had in fact exceeded 10,000'), which should have warned the crew of
any insidious problem before they became unable to respond.
