Felix Baumgartner; born 20 April 1969) is an Austrian skydiver, daredevil and BASE jumper. He set the world record for skydiving an estimated 39 kilometres (24 mi), reaching an estimated speed of 1,342 kilometres per hour (834 mph), or Mach 1.24, on 14 October 2012, and became the first person to break the sound barrier without vehicular power on his descent. He is also renowned for the particularly dangerous nature of the stunts he has performed during his career. Baumgartner spent time in the Austrian military where he practised parachute jumping, including training to land on small target zones.

Baumgartner's most recent project was Red Bull Stratos, in which he jumped to Earth from a helium balloon in the stratosphere on 14 October 2012. As part of this project, he set the altitude record for a manned balloon flight, parachute jump from the highest altitude, and greatest free fall velocity.

In January 2010, it was reported that Baumgartner was working with a team of scientists and sponsor Red Bull to attempt the highest sky-dive on record.

The launch was originally scheduled for 9 October 2012, but was aborted due to adverse weather conditions. Launch was rescheduled and the mission instead took place on 14 October 2012 when Baumgartner landed in eastern New Mexico after jumping from a world record 39,045 metres (128,100 ft) or just over 39 kilometres (24 mi).On the basis of provisional data, Baumgartner also set the record for the highest manned balloon flight (at the same height) and fastest speed of free fall at 1,342 kilometres per hour (834 mph) making him the first human to break the sound barrier outside of a vehicle. Baumgartner was in free fall for 4 minutes and 19 seconds, 17 seconds short of mentor Joseph Kittinger's 1960 jump.
