Emergency oxygen generators for pax only last for a few minutes. Once the generator is depleted, you can suck on that mask all you want until you pass out.

[Q] How many deliberate, pilot-caused crashes has the world had since 9-11?

I know here in the US, almost every foreign student pilot has to undergo a homeland security background check prior to receiving training. Obviously, the government knows that passengers are not the only threat to air safety.

And then there is my neighbor, who is just a f***ing idiot. If I got on a US Air flight and found out he was the pilot, I would demand to be let off the plane. Seriously. The guy is as unstable as a fat chick on a tightrope.
