Leroy Gordon "Gordo" Cooper Jr. (1927-2004) was an aerospace engineer and air force pilot who became one of the seven original astronauts in Project Mercury, the United States' first manned space program. In 1963 he piloted the final Mercury spaceflight and was the last American to fly an entirely solo orbital mission. Two years later Cooper served as command pilot of Gemini 5 on an eight-day mission alongside astronaut Pete Conrad. In 1970, having flown 222 hours in space, he retired from NASA and the air force at the rank of colonel.
After leaving NASA, Cooper served on numerous corporate boards and was a technical consultant in such fields as high-performance boat design, construction, and energy. He also worked for the Walt Disney Company as vice president of research and development for Epcot. His hobbies included deep-sea salvaging and designing aircraft inspired by the UFOs he observed and studied during his career as a pilot and astronaut.
