I must admit I haven't read the whole of this thread but,
It seems to me that we pilots are not very good at identifying, facing up to and dealing with the obvious dangers of hypoxia for all the well known and accepted reasons.
Surely there should be a case for providing both pilots with an automatic drop down O2 system, similar to the system that the pax have.
Yes it would be expensive and difficult to retrofit and a million other excuses BUT it should hopefully provide the crew with auto O2 when they most need it.
We just then need someway of automatically clamping the mask onto his or her face......solutions, please. Not blame.
