Kittinger was a US Air Force test pilot when he made his record-setting jump from an open, unpressurised gondola, long before anyone had rocketed into space. Now 83, Kittinger lives near Orlando, Florida, and has been working with Baumgartner for three years. He took part in Thursday's test. Kittinger is amazed no one has broken his free-falling record, after so many decades. "In the 52 years since I did it, there have been a lot of improvements in pressure suits, in communications and life-support systems. But the only thing that really has not changed is how hostile it is at that altitude," Kittinger said. "It's almost a complete vacuum."
