Felix Baumgartner's huge leap

In October 2012, skydiver and former Austrian paratrooper Felix Baumgartner was watched live by millions as he ascended into the stratosphere in a helium balloon. He then jumped an estimated 38km from space back to earth. In doing so, he broke the speed of sound and the highest skydive record that had lasted more than 50 years. Felix tells Dan Hardoon about his big leap.A Whistledown production for BBC World Service.(Photo: Felix Baumgartner jumping from space. Credit: Getty Images)
