The Royal Australian Air Force's Aircraft Research and Development Unit (ARDU) plans, conducts and analyses the results of ground and flight tests of existing and new Air Force aircraft.
 ARDU consists of four flights located at RAAF Bases Edinburgh, Amberley, Richmond and Williamtown, staffed by qualified test pilots, flight test engineers and flight test system specialists.
 Up until 2016 the Squadron also conducted flight test for the Australian Army with Army personnel also working within the unit.
 The flight test crew are long course trained at test pilot schools including the United States Air Force Test Pilot School, the United States Naval Test Pilot School, the Empire Test Pilots' School, the École du personnel navigant d'essais et de réception and the National Test Pilot School.
Frank Frederick Borman II (born March 14, 1928), (Col, USAF, Ret.)
, is a retired United States Air Force pilot, aeronautical engineer, test pilot, and NASA astronaut, best remembered as the Commander of Apollo 8, the first mission to fly around the Moon, making him, along with crew mates Jim Lovell and Bill Anders, the first of only 24 humans to do so.
 Before flying on Apollo, he set a fourteen-day spaceflight endurance record on Gemini 7, and also served on the NASA review board which investigated the Apollo 1 fire.
 After leaving NASA, he was the Chief Executive Officer (CEO) of Eastern Air Lines from 1975 to 1986.
 Borman is a recipient of the Congressional Space Medal of Honor.
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.
James Alton "Jim" McDivitt (born June 10, 1929), (Brig Gen, USAF, Ret.)
, is an American former test pilot, United States Air Force pilot, aeronautical engineer, and NASA astronaut who flew in the Gemini and Apollo programs.
 He commanded the Gemini 4 flight during which Edward H. White performed the first U.S. spacewalk, and later the Apollo 9 flight which was the first manned flight test of the Lunar Module and the complete set of Apollo flight hardware.
 He later became Manager of Lunar Landing Operations and was the Apollo Spacecraft Program Manager from 1969 to 1972.
Joseph Albert "Joe" Walker (February 20, 1921 – June 8, 1966) flew the world's first two spaceplane flights in 1963, thereby becoming the United States' seventh man in space.
 Walker was a Captain in the United States Air Force, an American World War II pilot, an experimental physicist, a NASA test pilot, and a member of the U.S. Air Force Man In Space Soonest spaceflight program.
 His two X-15 experimental rocket aircraft flights in 1963 that exceeded the Kármán line – the altitude of 100 km , generally considered to mark the threshold of outer space – qualified him as an astronaut under the rules of the U.S. Air Force and the Fédération Aéronautique Internationale (FAI).
Kenneth O. "K.O." Chilstrom (born April 20, 1921) is a retired United States Air Force officer, combat veteran, test pilot, and author.
 He was the first USAF pilot to fly the XP-86 Sabre, chief of fighter test at Wright Field, commandant of the U.S. Air Force Test Pilot School, and program manager for the XF-108 Rapier.
 Chilstrom was a pilot in the first jet air race and delivered the first air mail by jet.
 He flew over eighty combat missions in the Italian Campaign of World War II and tested over twenty foreign models of German and Japanese fighters and bombers to evaluate their strengths and weaknesses.
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.
Leroy Gordon "Gordo" Cooper Jr. (March 6, 1927 – October 4, 2004), (Col, USAF), better known as Gordon Cooper, was an American aerospace engineer, test pilot, United States Air Force pilot, and one of the seven original astronauts in Project Mercury, the first manned space program of the United States.
The Mercury Seven were the group of seven Mercury astronauts announced by NASA on April 9, 1959.
 They are also referred to as the Original Seven or Astronaut Group 1.
 They piloted the manned spaceflights of the Mercury program from May 1961 to May 1963.
 These seven original American astronauts were Scott Carpenter, Gordon Cooper, John Glenn, Gus Grissom, Wally Schirra, Alan Shepard, and Deke Slayton.
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.
