The pedants will no doubt point out that Felix Baumgartners attempt to make the highest ever skydive from 120,000ft 36.5km is nowhere near space; and of course, theyd be right – the so-called Karman line is judged to be at about 100km 328,000ft. But this kind of misses the point.At the altitude the Austrian daredevil intends to leap out of his capsule, the air pressure is less than 2% of what it is at sea level. Hell be jumping into a near vacuum. Hes all but in space.Its been a long road for Baumgartner. He first discussed with his sponsors Red Bull the idea of breaking Col Joe Kittingers 52-year-old parachute mark back in 2005.
