He was bidding to break records set over 50 years ago by Joseph Kittinger, now a retired US Air Force colonel who made a freefall jump from 102,800 feet (31,333 meters) in 1960. Kittinger was part of Baumgartner's backup team.
Citing preliminary figures, she said the whole jump lasted nine minutes and three seconds, including 4 minutes and 44 seconds after he deployed his parachute to float down to earth in the New Mexico desert.
Baumgartner had hoped to be in freefall for more than five minutes before opening his chute, and had also expected to jump from a lower altitude -- 120,000 feet.
The reason for the shorter than expected freefall was not immediately clear, although live commentary during the unprecedented leap suggested he opened his parachute at an altitude above the 5,000 feet level announced in advance.
