Friday, 9.30pm, BBC Knowledge When Austrian daredevil Felix Baumgartner rose to the edge of space on a balloon and jumped from a height of 39km to land safely on the ground last year, vision of him calmly stepping into the void captured the world’s attention. For many, the historic jump was a scientific breakthrough on par with the moon landing. What we didn’t see at the time is how close to disaster the mission came, on the way up and on the way down. We didn’t see the conflicts between Baumgartner and his team during four long years of preparation, or give much thought to the NASA-like technological backbone of the expedition. This feature-length documentary gives us the full story behind the space dive. From childhood, Baumgartner says, he has dreamed of flying. He wants to fly higher, faster and farther than any human has dared. But first he has to break a record that has stood for more than 50 years. You see, in 1960, test pilot Joe Kittinger volunteered to test survival at the edge of the Earth’s atmosphere. Wearing just a pressure suit, he survived the 30.5km plunge back to Earth. Who better to mentor Baumgartner in his quest? Kittinger helps Baumgartner break his record and become the first man to fall faster than the speed of sound.
