As the sun rises, workers prepare at the launch site, ahead of an attempt by Felix Baumgartner to break the speed of sound with his own body by jumping from a space capsule lifted by a helium balloon. Baumgartner plans to jump from an altitude of 120,000 feet, an altitude chosen to enable him to achieve Mach 1 in free fall, which would deliver scientific data to the aerospace community about human survival from high altitudes.
