I am sorry Jim, the O2 is for emergency use. The cabin is pressurized
from engine bleed air. The O2 masks drop from the ceiling at 14K' cabin
altitude just like the airliners.

Yep, that's what I thought.

Sorry you misunderstood me, and I misunderstood you.

This went back to the possibility of oxy causing the Payne Stewart crash,
when I replied it was not likely because that was believed to be a primary
pressurization problem.

The Lear does have an emergency pressurization system. When the cabin
altitude reaches (I believe) 12,000' there is a valve that opens and puts
full, uncooled bleed air into the cabin. There is no mistaking when this
happens; it is loud and it is hot.
