Gordon Cooper
Mercury-Atlas 9 astronaut and decorated test pilot who witnessed multiple UFO sightings and formally petitioned the United Nations for coordinated study of extraterrestrial contact.
Early Career and Credentials
Leroy Gordon Cooper Jr. was born in Shawnee, Oklahoma, in 1927. A career Air Force pilot and test pilot at Edwards Air Force Base, Cooper became one of NASA's original Mercury Seven astronauts—the first group selected for the American spaceflight program. In May 1963, he flew Mercury-Atlas 9 (Mercury-9), orbiting Earth 22 times aboard Faith 7 in a 34-hour mission, making him the last American to fly into space alone. He later flew Gemini-5 in 1965. His technical credentials and calm demeanor under pressure made him a trusted voice in both military and civilian aviation circles.
UFO Encounters
Cooper's first major UFO encounter occurred in 1951 while he was stationed with a fighter pilot group in Germany. He witnessed an entire formation of circular, disc-shaped objects passing over the airbase on a near-daily basis. Cooper reported that these craft exhibited flight characteristics—speed, maneuverability, and coordinated movement—that exceeded any known conventional aircraft of that era. The objects' synchronized formations suggested intelligent control and communication between vessels.
The second significant encounter came in 1957 at Edwards Air Force Base. During his tenure as a test pilot, Cooper and other witnesses observed what he described as a saucer-shaped metallic craft land on the dry lakebed at Edwards. A film crew captured footage of the landing, which was subsequently sent to Washington, D.C. However, Cooper never received official confirmation or follow-up from authorities, contributing to his growing conviction that a systematic coverup was occurring.
Importantly, Cooper consistently and emphatically denied a persistent urban legend that he had witnessed a UFO during his 1963 Mercury flight. Despite repeated claims in popular media, Cooper's testimony was clear: his spaceflight yielded no UFO sightings. This integrity in distinguishing his actual experiences from apocryphal accounts strengthened his credibility on other matters.
UN Testimony and Diplomatic Advocacy
Cooper became one of the most credible figures in UFO disclosure advocacy. On November 9, 1978, he sent a formal letter to the Ambassador of Grenada to the United Nations, expressing his belief that "extra-terrestrial vehicles and their crews are visiting this planet from other planets, which obviously are a little more technically advanced than we are here on earth." He called for "a top level, coordinated program to scientifically collect and analyze data from all over earth concerning any type of encounter, and to determine how best to interface with these visitors in a friendly fashion."
Seven years later, in 1985, Cooper addressed a UN panel discussion on UFOs and extraterrestrial life, with the panel chaired by then-Secretary-General Kurt Waldheim. In this forum, Cooper stated: "I believe that these extraterrestrial vehicles and their crews are visiting this planet from other planets which obviously are a little more technically advanced than we are here on Earth." His formal testimony lent unprecedented weight to UFO disclosure discussions, as it came from an American astronaut with unimpeachable military credentials.
Legacy and Impact
Unlike many UFO witnesses who faced ridicule or career consequences, Cooper's established reputation as a Mercury Seven astronaut insulated him from dismissal. He maintained his testimony and advocacy until his death in 2004, never wavering or recanting his UFO claims. His willingness to engage formal diplomatic channels—the United Nations—rather than relying solely on media interviews distinguished his approach from many contemporaries. Cooper's voice carried weight in circles that might otherwise dismiss UFO testimony as sensationalism.
