Joe Henry Engle (born August 26, 1932), (Maj Gen, USAF, Ret.)
, is an American pilot who served in the United States Air Force, test pilot for the North American X-15 program, aeronautical engineer, and a former NASA astronaut.
 As of 2017, he is the last living pilot of the X-15 program.
Stuart Allen "Stu" Roosa (August 16, 1933 – December 12, 1994), (Col, USAF), was an American aeronautical engineer, United States Air Force pilot, test pilot, and NASA astronaut, who was the Command Module Pilot for the Apollo 14 mission.
 The mission lasted from January 31 to February 9, 1971 and was the third mission to land astronauts (Alan Shepard and Edgar Mitchell) on the Moon.
 While Shepard and Mitchell spent two days on the lunar surface, Roosa conducted experiments from orbit in the Command Module "Kitty Hawk".
 He was one of only 24 people to travel to the Moon.
John Bevins Moisant (April 25, 1868 – December 31, 1910), known as the "King of Aviators," was an American aviator, aeronautical engineer, flight instructor, businessman, and revolutionary.
 As a pilot, he was the first to conduct passenger flights over a city (Paris), as well as across the English Channel, from Paris to London.
 He also co-founded a prominent flying circus, the Moisant International Aviators.
Robert Michael "Bob" White (July 6, 1924 – March 17, 2010), (Maj Gen, USAF), was an American military aircraft test pilot, fighter pilot, electrical engineer, and a Major general in the United States Air Force.
 White broke a number of records with the North American X-15 experimental aircraft during the 1960s, and supervised the design and development of several modern military aircraft.
X-15 Flight 3-65-97, also known as X-15 Flight 191, was a test flight of the North American X-15 experimental aircraft.
 It took place on November 15, 1967, and was piloted by Michael J. Adams.
 It ended in tragedy when the aircraft broke apart minutes after launch due to technical difficulties, killing the pilot and destroying the plane.
Alan LaVern Bean (born March 15, 1932), (CAPT, USN, Ret.)
, is an American former naval officer and Naval Aviator, aeronautical engineer, test pilot, and NASA astronaut; he was the fourth person to walk on the Moon.
 He was selected to become an astronaut by NASA in 1963 as part of Astronaut Group 3.
 He made his first flight into space aboard Apollo 12, the second manned mission to land on the Moon, at the age of thirty-seven years in November 1969.
 He made his second and final flight into space on the Skylab 3 mission in 1973, the second manned mission to the Skylab space station.
 After retiring from the United States Navy in 1975 and NASA in 1981, he pursued his interest in painting, depicting various space-related scenes and documenting his own experiences in space as well as that of his fellow Apollo program astronauts.
William John "Pete" Knight (November 18, 1929 – May 7, 2004), (Col, USAF), was an American aeronautical engineer, politician, Vietnam War combat pilot, test pilot, and astronaut in the X-20 Dyna-Soar and North American X-15 programs.
 Knight holds the world's speed record for flight in a winged, powered aircraft.
James Benson "Jim" Irwin (March 17, 1930 – August 8, 1991) (Col, USAF) was an American astronaut, aeronautical engineer, test pilot, and a United States Air Force pilot.
 He served as lunar module pilot for Apollo 15, the fourth human lunar landing.
 He was the eighth person to walk on the Moon and the first, and youngest, of those astronauts to die.
Robert Franklyn "Bob" Overmyer (July 14, 1936 – March 22, 1996), (Col, USMC), was an American test pilot, naval aviator, aeronautical engineer, physicist, United States Marine Corps officer, and USAF/NASA astronaut.
 He was born in Lorain, Ohio, but considered Westlake, Ohio his hometown.
 Overmyer was selected by the United States Air Force as an astronaut for its Manned Orbiting Laboratory in 1966.
 Upon cancellation of this program in 1969, he became a NASA astronaut and served support crew duties for the Skylab program and Apollo-Soyuz Test Project.
 In 1976, he was assigned to the Space Shuttle program, and flew as pilot on STS-5 in 1982, and as commander on STS-51-B in 1985.
 He was selected as a lead investigator into the Space Shuttle "Challenger" disaster, and retired from NASA in 1986.
 Ten years later, Overmyer died in Duluth, Minnesota while testing the Cirrus VK-30 composite homebuilt aircraft.
Michael James "Mike" Adams (May 5, 1930 – November 15, 1967), (Maj, USAF), was an American aviator, aeronautical engineer, and USAF astronaut.
 He was the first American space mission fatality, according to the United States definition.
