This is one of the most beautiful clips I have seen on Youtube.
The footage is from Project Excelsior, in which Joseph Kittinger jumped from an altitude of over 102,000' and fell to earth at supersonic speeds. The music is Boards of Canada's song "Dayvan Cowboy"
This is beautiful, and it's also very sad. It's only a cartoon, but that doesn't matter. It's "Hunted by a freak" by the band Mogwai.
