Want to watch a human break the sound barrier? Austrian daredevil, Felix Baumgartner, whose Sunday freefall was watched around the world, was at one point traveling at 833 mph or Mach 1.24, shattering the speed of sound during his 4 minute 20 second freefall. He is the only human to do so without the aid of a supersonic jet or space shuttle.
The last word Felix Baumgartner said before he launched himself from a capsule floating at around 39 kilometres above the surface of the Earth just after 12pm local time in Roswell, New Mexico was "I'm coming home now."
