Caught the tail end of a
FlightLine (Discovery Wings) with that bloke with the long hair taking a Gulfstream V up to 51000 feet.
Interestingly the other pilot had to wear an oxygen mask
all the time above something like 41000 feet.
Also in the event of a pressurization failure the thing doves in automatically orchestrated by the electronics.
Not sure I fancy having to wear that mask all the time though
