The real question was:
Why would you want to fly for 3.5 hours at the edge of a condition which
the FARs state is only safe for 30 minutes or less?

Why would you automatically assume that because something is LEGAL that it
is also automatically safe?


I didn't say it was safe. I said that the FARs said it was safe.

That was a slight mis-type in that actually I meant that the FARs *implied*
it was safe.

Therefore they imply that above 12,500 for more than 30 mins without oxygen
is unsafe. Certain things I accept as the cumulative knowledge of those who
went before me :-)
