Officials say that Felix Baumgartner has become the first skydiver to break the speed of sound.
At a news conference, Brian Utley of the International Federation of Sports Aviation said Baumgartner reached a maximum speed of 833.9 mph during his jump Sunday over the New Mexico desert.
That amounts to Mach 1.24, which is faster than the speed of sound.
No one has ever reached that speed wearing only a high-tech suit.
Baumgartner says that traveling faster than sound is "hard to describe because you don't feel it." With no reference points, "you don't know how fast you travel."
Baumgartner came down safely in the eastern New Mexico desert about nine minutes after jumping from his capsule 128,100 feet, or roughly 24 miles, above Earth.
