Today, at about 8:30 am EST, Felix Baumgartner will ride in a capsule, lifted by a helium balloon that is taller than the Statue of Liberty, to about 120,000ft (22.73 miles.) Then he's going to jump out, from the edge of space, and attempt to break the sound barrier in freefall.
his balloon will rise between 1,000 to 1,400 meters/min, slowing to around 750 feet/min around 100,000 feet above sea level. (sounds like a deflating birthday balloon darting around a room.)
opening chutes at those speeds seems like when we were kids trying to slow our fall with an umbrella or bed sheet (from a tree or roof.)
i hope he does it. sonic boom
