Skydiver aims to go supersonic

"Fearless Felix" Baumgartner has jumped 2,500 times from planes and helicopters, as well as some of the highest landmarks and skyscrapers on the planet — the Christ the Redeemer statue overlooking Rio de Janeiro, the Millau Viaduct in southern France, the 101-story Taipei 101 in Taiwan. This summer, Baumgartner hopes to hurtle toward Earth at supersonic speed from a record 23 miles up, breaking the sound barrier with only his body.
