Beags,
Good post.
The idea that performance of the pilot can be meaningfully analysed in these circumstances is absurd.
The instant any form of oxygen shortage impacts the brain a whole raft of physiological implications kick in...different in everybody and in each circumstance. They would have had to have had the poor chap wired up with all that crap the astronaults wear, with a squad of flight surgeons chewing it through in real time to get any useful data on how he was reacting...and even then it would count for little more than the square root of **** all.
I remember an occasion at North Luffenham when they blew the chamber with 8 of us on board for rapid decompression drills. Seven of us took our masks off and started chirping down from 100 (minus 7 each time as I recall) IAW the brief. The eighth took his mask off, glazed over and pitched foward out for the count (excuting a near perfect Glasgow Kiss on the onboard medic who was leaning into him, LOL). Seemed he suffered from some sort of shock reaction.
Aircraft and pilot lost due to malfunction...end of. RIP.
