Red Bull is sponsoring a sky dive from a balloon 23 miles high, which aims to get this gentleman, Austrian madman Felix Baumgartner, to break the speed of sound.
This jump will also break the record for the highest parachute jump, set by Captain Joe Kittinger in 1960. Kittinger jumped from 102,800 feet (about 19.4 miles), and reached a top speed of 614 mph.
Looking forward to watching it, Felix. That's an awesome name, by the way.
