7. High-altitude accident Indeed, Kittinger's successful leap did not spell safety for everyone trying such a stunt. In 1962, Soviet Air Force Colonel Pyotr Ivanovich Dolgov attempted a jump from 93,970 feet (28,640 m) as part of a project testing a new pressure suit. Dolgov's visor hit the gondola from which the man leapt.
The suit depressurized, and Dolgov died before he reached the ground.
