NEW MEXICO (WFXT/MyFoxBoston.com)—According to the official numbers released Monday, supersonic sky diver Felix Baumgartner, known as "Fearless Felix", reached 843.6 mph. That's equivalent to Mach 1.25 -- or 1.25 times the speed of sound.
Last October, the Austrian parachutist's fall was initially estimated as 834 mph, or Mach 1.24.
Either way, "Fearless Felix", is the first human to break the sound barrier with only his body.
The leap was from an altitude of 127,852 feet and lasted for half a minute.
