spaceship one

It's all a question of partial pressure. At 29,280 feet, even 100%
oxygen is barely capable of keeping a human alive, never mind let them
do any type of serious exercise (which is why 8000 meter mountains are
so hard).

I doubt the cabin was at much higher than 15,000 feet, probably lower
than that. Which makes the bird all the more impressive, to me.

When I was a kid, I thought the angel's name was Hark
and the horse's name was Bob.

Not quite. At that 29,000' 100% O2 is the same partial pressure as 20% O2
at sea level. Glider pilots reach these altitudes in unpressurized cockpits
all the time. The record altitude for a glider is just under 50,000' again
with no pressurization.

Did you know that Spaceship One is registered as a glider?
