Pilots are trained to 'detect' hypoxia but it is still /incredibly/ difficult.

>Even if there was a slow decompression to 13,500 ft cabin altitude, almost no one would be unconscious.

This person's theory claims that the autopilot would /maintain/ the aircraft's altitude. The cabin may slowly depressurise, but the altitude remains the same. TUC at 35,000 feet - normal cruise altitude - is only 30 to 60 seconds (on average!), which is nowhere near the 30 minute mark that it would be at <15,000 feet.

I am not experienced enough to comment on the plausibility of other aspects of this person's theory, but in terms of unconsciousness caused by decompression, it definitely seems plausible.

Though this article is likely dead I'll respond anyways. As the author notes, when cabin altitude reaches 13,500 ft, oxygen masks automatically deploy. This pretty much destroys the entire theory.

I agree about detecting hypoxia, it is very hard.
