bobbette: Red Bull sponsors all kinds of extreme shiat, although this might be the most dramatic to date.

I was at the Miramar Air Show watching their sponsored pilot do crazy shiat while their sponsored parachutist was doing crazy shiat in another state (the announcers were announcing the status of the balloon jump every now and then).

Just did some simple math, if you free fall 119,000ft in 4.2min, your average speed is 443ft/s. Now if you started at 128,000ft above the Earth, and something goes wrong when you pull your rip chord with 9,000ft to go, you have about 20 seconds left before you hit the ground and presumably, less than that if it takes a bit for your chute to open.

Estimating 4 seconds for the chute to open, and needing 3
seconds to decelerate from 443ft/s to 50ft/s, which would be about 4G's on the body, Felix Baumgartner gave himself a window of about 13 seconds if something had gone wrong with his first chute and needed to detach it and pull his reserve chute.

13 Seconds.

That's actually less than I thought it would be. Though your math is a bit off.

His freefall was 119,846 feet (or 22.7 miles) according to the post-jump press conference

His freefall time was 4 minutes, 19 seconds or 4.31 minutes or 259 seconds (from the linked site for this thread)

His average freefall velocity was 462.728 ft/s or 315.495 mph.

128,100 feet (his starting altitude) - 119,846 = 8254 feet or 1.56 miles

Just some crude math says that in truth, he might have had a 10 second window (still longer than I would think). But he was equipped with a parachute that was set to deploy automatically at 2000 feet.
