Leroy Gordon Cooper Jr. — one of the seven original Mercury astronauts — is the most credentialed U.S. military pilot to have made official documented reports of UAP encounters and to have subsequently advocated publicly for government transparency. He held TOP SECRET clearance, logged over 5,000 hours in aircraft, and flew the Mercury-Atlas 9 Faith 7 mission in 1963. Unlike many UAP witness accounts, Cooper's encounters generated official Air Force documents: the 1951 Neubiberg sighting produced an intelligence filing, and the 1957 Edwards Air Force Base landing was filmed by a camera crew working under Cooper's direction — and the film was sent to the Pentagon, where it entered the classified file system.
In 1951, then-Captain Gordon Cooper was stationed at Neubiberg Air Base, West Germany, flying F-86 Sabre jets with the 525th Fighter Bomber Squadron. On multiple days in 1951, Cooper and other pilots from the base observed large formations of metallic-looking disc-shaped objects flying over the base at high altitude — much higher than the F-86s could reach. The objects flew in formation and maintained altitude beyond the operational ceiling of any known aircraft at the time. Cooper later described them as 'saucer-shaped' and 'flying in formation at extremely high altitude.'
The encounters were officially reported through the Air Force intelligence chain and filed as unidentified. This was during the period of Project Grudge (which preceded Project Blue Book), and the encounters became part of the institutional record that contributed to the creation of Project Blue Book in 1952. Cooper's reporting of the Neubiberg encounters through proper Air Force channels — rather than as a civilian witness — gives them a different archival standing: they are part of the Air Force's internal documentation of pilot observations, not a civilian report.
The more significant of Cooper's documented encounters occurred on May 3, 1957, at Edwards Air Force Base, California. Cooper was in charge of an experimental aircraft photographic team that day. A metallic, saucer-shaped object descended near the dry lakebed at Edwards, hovered briefly, and then ascended and departed at high speed. The event was observed by multiple members of the camera team. Cooper directed his photographers to film the object; they captured footage of the disc during its hover and departure.
Cooper personally delivered the film to his superiors and filed an official report. He reported that the film was sent to Washington D.C. — to what he understood to be the Pentagon — and that he never saw it again. In subsequent years, the footage was never publicly released. Cooper maintained consistently that he filed the report through proper channels and that the film entered classified custody. The Edwards incident is particularly significant because it involved multiple witnesses, professional photographic documentation under a supervised military camera team, and official reporting by a commissioned officer who would go on to the Mercury program.
In 1978, Gordon Cooper submitted a written statement to the United Nations Special Political Committee during deliberations about the establishment of an international UAP research program. In the statement, Cooper wrote that he firmly believed in the existence of intelligent beings from other planets and stated that UAP were real, structured craft not manufactured on Earth. He called for an international scientific investigation and expressed frustration that UAP reports by qualified observers were being systematically dismissed.
Cooper's 1978 UN testimony was a significant public act — a former astronaut and test pilot with active involvement in classified programs making an official statement to the United Nations. It put his credibility behind UAP transparency in a way that predated the modern disclosure movement by decades. He continued to speak publicly about UAP throughout his life, maintaining consistency in his accounts and never walking back his 1951 or 1957 reports. He died in 2004 — the same year as the USS Nimitz Tic Tac encounter.
Gordon Cooper's UAP accounts occupy a specific and important niche in the official record. He is not a civilian witness who happened to observe something unusual — he is a professional military test pilot with TOP SECRET clearance, a documented chain of official reporting for both his major encounters, and a formal UN submission. His Edwards AFB film, if it still exists in the classified system, would represent one of the oldest pieces of photographic evidence of a UAP in U.S. government custody.
Cooper's accounts predate the post-2004 era of Navy UAP encounters but are consistent with the same operational pattern: trained military observers, multiple witnesses, official reporting through proper channels, and subsequent disappearance of the documentation into classified custody. In the context of the PURSUE releases and NARA RG 615, the Cooper cases represent the pre-Blue Book and early Blue Book era of the archive — the period before the formal UAP investigation framework was established and where documentation is most sparse. His 1957 Edwards AFB report has been requested under FOIA with no confirmation of existing records, consistent with either permanent classification or destruction.
