Editing Sound barrier (section)

====Felix Baumgartner====
In October 2012 [[Felix Baumgartner]], with a team of scientists and sponsor Red Bull, attempted the highest sky-dive on record. The project would see Baumgartner attempt to jump 120,000&nbsp;ft (36,580&nbsp;m) from a helium balloon and become the first parachutist to break the sound barrier. The launch was scheduled for 9 October 2012, but was aborted due to adverse weather; subsequently the capsule was launched instead on 14 October. Baumgartner's feat also marked the 65th anniversary of U.S. test pilot [[Chuck Yeager]]'s successful attempt to break the sound barrier in an aircraft.<ref name="ABC"/>

Baumgartner landed in eastern New Mexico after jumping from a world record 128,100&nbsp;feet (39,045&nbsp;m), or 24.26&nbsp;miles, and broke the sound barrier as he traveled at speeds up to 833.9&nbsp;mph (1342&nbsp;km/h, or Mach 1.26). In the press conference after his jump, it was announced that he was in freefall for 4&nbsp;minutes 18&nbsp;seconds, the second longest freefall after the 1960 jump of [[Joseph Kittinger]] for 4&nbsp;minutes 36&nbsp;seconds.<ref name="ABC">Sunseri, Gina and Kevin Doak.
