Watch video: Florida man parachutes from 100,000 feet
Felix Baumgartner has jumped off two of the tallest buildings in the world, as well as the statue of Christ in Rio de Janeiro (a 95-foot leap for which he claimed a low-altitude record for parachuting.) Now Fearless Felix, as his fans call him, has something more difficult on the agenda: jumping from a helium balloon in the stratosphere at least 120,000 above Earth. Within about half a minute, he figures, he would be going 690 miles per hour and become the first parachuter to break the speed of sound.
The current holder of the skydiving record is Joe Kittinger from Orlando. Watch video from Kittinger's jumps:
