1960-08-18 USA Discoverer 14

Discoverer 14 was a US spy satellite used in the Corona program managed by Advanced Research Projects Agency (ARPA) of the Department of Defense and the United States Air Force. On 19 August 1960, usable photographic film images of the Soviet Union taken by the satellite were recovered by a C-119 recovery aircraft. This was the first successful recovery of film from an orbiting satellite and the first mid-air recovery of an object returning from Earth orbit.
