Scott,

why don't you re-read my post you clipped from?  I guess I can never know if
I really passed out or not, since I wasn't conscious to evaluate it.

I'd imagine the hypoxia you're exposed to in flight training is deliberately
gradual to give you the experience of slow-onset hypoxia, which is likely to
be the only kind you have a chance to recover from.  Why don't you ask
someone at NASA what their exact training protocol is before speculating
that you know it?

Or you could ask Payne Stewart and his pilots how fast hypoxia can be,
except they're all dead.
