The trouble started just a few seconds after the jump:
He began spinning. Slowly at first:
Then a little faster. WEEEEEEEEE, wait. WAIT
OOHHHH SHIT, NOPE, I WANT TO GET OFF THIS RIDE
AAAHHHHHHHHGGHHHGHH
Luckily, he regained control as he slowed down. Everything turned out fine:
Baumgartner "really thought [he was] in trouble," he told reporters. The spinning had almost knocked him out, but had he pulled his smaller chute, for stabilization, he never would have broken the sound barrier.
