On 1 November 1962, Dolgov and
Major Yevgeni Nikolayevich Andreyev ascended in a Volga
balloon gondola from
Volsk, near
Saratov, to make high-altitude parachute jumps. Andreyev successfully completed his jump. Dolgov, testing an experimental
pressure suit, jumped at . The helmet visor of Dolgov's pressure suit hit part of the gondola as he exited, and the suit
depressurized, killing him. On 12 December 1962, Dolgov was posthumously named a
Hero of the Soviet Union. If Dolgov's jump had been successful, he still would not have exceeded the record set by
Joseph Kittinger for the highest-altitude parachute jump in history (, 16 August 1960). The current world record is held by
Alan Eustace (, 24 October 2014). ==Legacy==
