In October 2012, Felix Baumgartner accomplished the amazing when he leaped from a balloon floating 128,100 feet above the ground and reached over 800 mph on the way down; faster than the speed of sound.
Footage taken by the multiple GoPro cameras mounted on Baumgartner's suit has finally been released, and it's absolutely incredible.
You should definitely watch it in full-screen HD with headphones on.
