Joe Kittinger was the first human to jump from space to the Earth. It took bravado true bravado. KIittinger first went up in a balloon in the upper reaches of the atmosphere. then he jump from heights as high as 100,000 feet in free falls to Earth. He almost died once and on one mission, a leak in his spacesuit caused his hand to swell up to several times its size. He also fell unconsious once on a dive. His dives were necessary so that NASA could test the effect of radiation, and of being in space, on the human body. Jon Kittinger: a true pioneer, hero and brave man.
