United States Naval Aviator in the context of "John Young (astronaut)"

Richard Francis "Dick" Gordon Jr. (October 5, 1929 – November 6, 2017) was an American naval officer and aviator, test pilot, and NASA astronaut, and a football executive. He was one of 24 people to have flown to the Moon, as command module pilot of the Apollo 12 mission, which orbited the Moon 45 times. Gordon had already flown in space as the pilot of the 1966 Gemini 11 mission.

Bruce McCandless II (born Byron Willis McCandless; June 8, 1937 – December 21, 2017) was an American Navy officer and aviator, electrical engineer, and NASA astronaut. In 1984, during the first of his two Space Shuttle missions, he completed the first untethered spacewalk by using the Manned Maneuvering Unit.

Scott Joseph Kelly (born February 21, 1964) is an American engineer, retired astronaut, and naval aviator. A veteran of four space flights, Kelly commanded the International Space Station (ISS) on Expeditions 26, 45, and 46.

Kelly's first spaceflight was as pilot of Space Shuttle Discovery during STS-103 in December 1999. This was the third servicing mission to the Hubble Space Telescope, and lasted for just under eight days. Kelly's second spaceflight was as mission commander of STS-118, a 12-day Space Shuttle mission to the ISS in August 2007. Kelly's third spaceflight was as a crewmember on Expedition 25/26 on the ISS. He arrived at the ISS aboard Soyuz TMA-01M on October 9, 2010, and served as a flight engineer until he took over command of the station on November 25, 2010, at the start of Expedition 26. Expedition 26 ended on March 16, 2011, with the departure of Soyuz TMA-01M.

Charles "Pete" Conrad Jr. (June 2, 1930 – July 8, 1999) was an American NASA astronaut, aeronautical engineer, naval officer, aviator, and test pilot who commanded the Apollo 12 mission, on which he became the third person to walk on the Moon. Conrad was selected for NASA's second astronaut class in 1962.

Conrad was born in Philadelphia, Pennsylvania. Despite having dyslexia, he earned his Bachelor of Science degree in aeronautical engineering from Princeton University—being the first Ivy League astronaut—and joined the U.S. Navy. In 1954, Conrad received his naval aviator wings, served as a fighter pilot and, after graduating from the U.S. Naval Test Pilot School (Class 20), as a project test pilot. In 1959, he was an astronaut candidate for Project Mercury.

Paul Joseph Weitz (July 25, 1932 – October 22, 2017) was an American naval officer and aviator, aeronautical engineer, test pilot, and NASA astronaut, who flew into space twice. He was a member of the three-man crew who flew on Skylab 2, the first crewed Skylab mission. He was also commander of the STS-6 mission, the maiden flight of the Space Shuttle Challenger.
