Gordon Cooper (born March 6, 1927; died October 4, 2004): the astronaut who believed UFOs( Unidentified Flying Objects) were real. Leroy Gordon Cooper Jr. was one of America’s original Mercury Seven astronauts and later commanded the long-duration Gemini 5 mission. Throughout his career he earned a reputation as a skilled Air Force pilot and respected astronaut.
Yet after leaving NASA, Cooper also became one of the best-known public figures to argue that some unidentified flying objects represented extraterrestrial spacecraft and that the U.S. government possessed evidence it was withholding from the public. Before becoming an astronaut, Cooper served as a U.S. Air Force fighter pilot and test pilot. In 1963 he became the last American to fly alone in space during the Mercury-Atlas 9 mission, spending more than 34 hours in orbit. In 1965 he commanded the Gemini 5 mission, setting a then-record for endurance in space. Because of these achievements, Cooper’s later comments on UFOs attracted considerable public attention.
The Edwards Air Force Base Story
One of Cooper’s most frequently repeated stories dated around 1957 while he was stationed at Edwards Air Force Base. According to Cooper, a camera crew working on a precision landing project reported filming a metallic, saucer-shaped; disc-shaped object that landed briefly on a dry lake bed. The object reportedly rested briefly on landing supports. The crew film it with high quality motion picture cameras. Before anyone could approach, it rose silently and took off at high speed.
Cooper said he viewed the developed film and believed it showed an extraordinary object unlike any conventional aircraft. Cooper said the crew members were experienced military personnel, not civilians looking for publicity. He stated that he watched the developed film himself and believed it showed an authentic unknown craft. He later said he mailed the film to military authorities in Washington, DC because that was standard procedure. He said he never learned what became of the film. The film has never been located, and no copy of the alleged film ever surfaced publicly. and no publicly available official records, nor any information from historians, have confirmed such an unusual incident.
Cooper’s Belief in Extraterrestrial Visitors
During interviews in the 1970s, 1980s, and 1990s, Cooper repeatedly expressed his conviction that some UFOs were spacecraft from other worlds. He argued that: Experienced military pilots had reported objects performing beyond known aircraft capabilities. Radar operators and military personnel had observed unexplained aerial phenomena. The evidence was too extensive to dismiss every report as mistaken observation. Cooper did not claim to have personally seen aliens. Rather, he believed that some UFO reports represented advanced vehicles operated by extraterrestrial intelligences.
Before joining NASA, Cooper was an Air Force fighter and test pilot. He believed that military pilots were trained observers who could distinguish conventional aircraft from something truly unusual. He often argued that when numerous experienced pilots independently reported objects performing extraordinary maneuvers, their testimony deserved serious consideration rather than ridicule. He pointed out that many such witnesses had little to gain professionally by reporting UFOs and, in some cases, risked damaging their careers.
Cooper often emphasized that he was influenced by conversations with fellow pilots and military officers. He believed many credible individuals had encountered:Metallic discs. Objects capable of sudden acceleration. Craft making right-angle turns at tremendous speeds. Vehicles that appeared to operate silently. He argued these reports came from disciplined observers familiar with aircraft.
In 1985 Cooper addressed members of the United Nations in connection with discussions about unidentified flying objects. He encouraged governments to cooperate internationally in investigating UFO reports and argued that the subject deserved careful scientific study instead of ridicule. Cooper eventually concluded that at least some UFOs originated beyond Earth. He reasoned that:Thousands of reports over decades were too numerous to dismiss entirely. Many came from trained military observers. The reported performance exceeded known human technology. Earth was unlikely to be the only inhabited world in the universe. He believed these points made extraterrestrial visitation the most plausible explanation for a subset of UFO cases.
Belief That the Government Was Hiding Evidence
One of Cooper’s strongest claims was that the U.S. government had recovered or collected important UFO evidence but was keeping it secret. He suggested that:Military agencies classified significant UFO reports. Important evidence never reached the public. National security concerns motivated secrecy. He often said the public deserved an honest investigation into the phenomenon.
However, Cooper never produced documentary proof showing that the government possessed crashed extraterrestrial spacecraft or alien bodies. His statements reflected his personal beliefs and experiences rather than evidence he could publicly verify. NASA has consistently stated that it has found no evidence that UFOs represent extraterrestrial spacecraft or that it is concealing evidence of alien visitors.
Likewise, no official U.S. government investigation has confirmed Cooper’s claims of extraterrestrial craft or a long-running cover-up.
In recent years, the U.S. government has acknowledged that some reports of Unidentified Anomalous Phenomena (UAP) remain unexplained after investigation. However, official reviews have not concluded that these objects are extraterrestrial. Cooper believed governments investigated UFO sightings far more seriously than they admitted publicly.
He noted that: Air Force personnel were instructed to report unusual aerial objects. Radar operators tracked unknown targets. Military intelligence gathered reports. From this, Cooper concluded that officials considered the phenomenon important even while publicly minimizing it.
Cooper believed several factors pointed toward official secrecy. He argued that: Important evidence disappeared into classified channels. Witnesses were discouraged from discussing incidents publicly. Governments wished to avoid public panic. Military agencies wanted to protect sensitive radar and intelligence capabilities. He did not claim to possess documents proving a conspiracy. Instead, he inferred secrecy from his own experiences and from what he believed had happened to reports such as the Edwards film.
Skeptical View
Researchers who remain skeptical of Cooper’s claims note several points: The Edwards Air Force Base film has never been publicly produced. No official records confirm the alleged saucer landing. Human memory can change over decades, especially when recounting events long after they occurred. Cooper’s reputation as an accomplished astronaut does not by itself establish the accuracy of every later recollection. In at least some cases, skeptics claim UFO reports can be based on misinterpretation of natural weather related or astronomical phenomena or new secret government state-of-the-art aircraft.
Countering The Skeptics
Cooper often emphasized that he was influenced by conversations with fellow pilots and military officers. He believed many credible individuals had encountered:Metallic discs. Objects capable of sudden acceleration. Craft making right-angle turns at tremendous speeds. Vehicles that appeared to operate silently. He argued these reports came from disciplined observers familiar with aircraft.
One of Cooper’s principal arguments concerned flight characteristics. He maintained that some reported UFOs displayed capabilities that remain a mystery to our level of technology such as: Instant super fast acceleration. Hovering without visible propulsion. Silent operation. Rapid changes in direction. Speeds beyond contemporary aircraft.
To Cooper, these characteristics suggested technology well beyond what any nation possessed during the 1940s and 1950s. Cooper believed governments investigated UFO sightings far more seriously than they admitted publicly. He noted that: Air Force personnel were instructed to report unusual aerial objects. Radar operators tracked unknown targets.
Military intelligence gathered reports. From this, Cooper concluded that officials considered the phenomenon important even while publicly minimizing it. And quirky weather events and strange astronomical phenomena, all completely nature, would have soon have been logically scientifically explained and adequately explained by professional weatherologists, astronomers, and astro-physicists who were part of the government board of the many investigative scientists regarding UFOs. The many types of UFOs that cannot be truthfully explained by natural, yet mysterious weather activity, nor by strange astronomical occurrences, nor by so-called “secret” “lateist advanced new experimental aircraft”; in which the UFOs exhibit signs of a super, super advanced technology not known by us earthlings; these are the UFOs Gordon Cooper knew were real and from extraterrestrials.
Legacy
Gordon Cooper occupies a unique place in UFO history. Unlike many UFO witnesses, he was one of America’s most accomplished astronauts and test pilots. His belief that extraterrestrial visitors had reached Earth—and that the U.S. government concealed important UFO evidence—gave the subject unusual visibility. At the same time, while Cooper consistently maintained these views until his death in 2004, the central claims he advanced have not been independently verified through publicly available physical evidence or official documentation.
As a result, his statements remain an important part of UFO history but continue to be debated by believers, skeptics, historians, and researchers alike. Leroy Gordon Cooper Jr. did not base his belief in extraterrestrial visitation on a single incident. Rather, over many years he described several experiences and observations that, taken together, convinced him that at least some UFOs were not human-made aircraft.
