A test pilot is an aircraft pilot with additional training to fly and evaluate experimental, newly produced and modified aircraft with specific maneuvers, known as flight test techniques. [2]
Test flying as a systematic activity started during the First World War, at the Royal Aircraft Establishment (RAE) in the United Kingdom. An "Experimental Flight" was formed at the Central Flying School. During the 1920s, test flying was further developed by the RAE in the UK, and by the National Advisory Committee for Aeronautics (NACA) in the United States. In the 1950s, NACA was transformed into the National Aeronautics and Space Administration, or NASA. During these years, as work was done into aircraft stability and handling qualities, test flying evolved towards a more qualitative scientific profession. In the 1950s, test pilots were being killed at the rate of about one a week,[ citation needed ] but the risks have shrunk to a fraction of that because of the maturation of aircraft technology, better ground-testing and simulation of aircraft performance, fly-by-wire technology and, lately, the use of unmanned aerial vehicles to test experimental aircraft features. Still, piloting experimental aircraft remains more dangerous than most other types of flying.
At the insistence of President Dwight D. Eisenhower, the first American astronauts, the Mercury Seven, were all military test pilots, as were some of the later astronauts.
The world's oldest test pilot school is what is now called the Empire Test Pilots' School (motto "Learn to Test – Test to Learn"), at RAF Boscombe Down in the UK. There are a number of similar establishments over the world. In America, the United States Air Force Test Pilot School is located at Edwards Air Force Base, the United States Naval Test Pilot School is located at Naval Air Station Patuxent River, Maryland and EPNER (Ecole du Personnel Navigant d'Essai et de Reception – "School for flight test and acceptance personnel"), the French test pilot school, is located in Istres, France. There are only two civilian schools; the International Test Pilots School in London, Ontario, and the National Test Pilot School, a not-for-profit educational institute is in Mojave, California. In Russia, there is a Russian aviation industry Fedotov Test Pilot School (founded 1947) [3] located in Zhukovsky within the Gromov Flight Research Institute.
Test pilots can be experimental and engineering test pilots (investigating the characteristics of new types of aircraft during development) or production test pilots (the more mundane role of confirming the characteristics of new aircraft as they come off the production line). Many test pilots would perform both roles during their careers. Modern test pilots often receive formal training from highly-selective military test pilot schools, but other test pilots receive training and experience from civilian institutions and/or manufacturers' test pilot development programs (see list of test pilot schools).
The National Advisory Committee for Aeronautics (NACA) was a United States federal agency founded on March 3, 1915, to undertake, promote, and institutionalize aeronautical research. On October 1, 1958, the agency was dissolved and its assets and personnel were transferred to the newly created National Aeronautics and Space Administration (NASA). NACA is an initialism, i.e., pronounced as individual letters, rather than as a whole word.
The Bell X-1 is a rocket engine–powered aircraft, designated originally as the XS-1, and was a joint National Advisory Committee for Aeronautics–U.S. Army Air Forces–U.S. Air Force supersonic research project built by Bell Aircraft. Conceived during 1944 and designed and built in 1945, it achieved a speed of nearly 1,000 miles per hour in 1948. A derivative of this same design, the Bell X-1A, having greater fuel capacity and hence longer rocket burning time, exceeded 1,600 miles per hour in 1954. The X-1 aircraft #46-062, nicknamed Glamorous Glennis and flown by Chuck Yeager, was the first piloted airplane to exceed the speed of sound in level flight and was the first of the X-planes, a series of American experimental rocket planes designed for testing new technologies.
Erich Karl Warsitz was a German test pilot of the 1930s. He held the rank of Flight-Captain in the Luftwaffe and was selected by the Reich Air Ministry as chief test pilot at Peenemünde West. He is remembered as the first person to fly an aircraft under liquid-fueled rocket power, the Heinkel He 176, on June 20, 1939 and also the first to fly an aircraft under turbojet power, the Heinkel He 178, on August 27 the same year.
The Douglas D-558-2 Skyrocket is a rocket and jet-powered research supersonic aircraft built by the Douglas Aircraft Company for the United States Navy. On 20 November 1953, shortly before the 50th anniversary of powered flight, Scott Crossfield piloted the Skyrocket to Mach 2, or more than 1,290 mph (2076 km/h), the first time an aircraft had exceeded twice the speed of sound.
Frederick Hamilton "Rick" Hauck is a retired captain in the United States Navy, a former fighter pilot and NASA astronaut. He piloted Space Shuttle mission STS-7 and commanded STS-51-A and STS-26.
Colonel Robert Franklyn "Bob" Overmyer was an American test pilot, naval aviator, aeronautical engineer, physicist, United States Marine Corps officer, and USAF/NASA astronaut. Overmyer was selected by the Air Force as an astronaut for its Manned Orbiting Laboratory in 1966. Upon cancellation of the program in 1969, he became a NASA astronaut and served support crew duties for the Apollo program, 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 in 1986, retiring from NASA that same year. A decade later, Overmyer died while testing the Cirrus VK-30 homebuilt aircraft.
The Northrop X-4 Bantam was a prototype small twinjet aircraft manufactured by Northrop Corporation in 1948. It had no horizontal tail surfaces, depending instead on combined elevator and aileron control surfaces for control in pitch and roll attitudes, almost exactly in the manner of the similar-format, rocket-powered Messerschmitt Me 163 of Nazi Germany's Luftwaffe. Some aerodynamicists had proposed that eliminating the horizontal tail would also do away with stability problems at fast speeds resulting from the interaction of supersonic shock waves from the wings and the horizontal stabilizers. The idea had merit, but the flight control systems of that time prevented the X-4 from achieving any success.
Joseph Albert Walker was an American World War II pilot, experimental physicist, NASA test pilot, and astronaut who was the first person to fly an airplane to space. He was one of twelve pilots who flew the North American X-15, an experimental spaceplane jointly operated by the Air Force and NASA.
Albert Scott Crossfield was an American naval officer and test pilot. In 1953, he became the first pilot to fly at twice the speed of sound. Crossfield was the first of twelve pilots who flew the North American X-15, an experimental spaceplane jointly operated by the United States Air Force and NASA.
William John "Pete" Knight was an American aeronautical engineer, politician, Vietnam War combat pilot, test pilot, and astronaut. He was one of twelve pilots who flew the North American X-15, an experimental spaceplane jointly operated by the U.S. Air Force and NASA.

John Barron McKay was an American naval officer, World War II pilot, aeronautical engineer, test pilot, and astronaut. He was one of twelve pilots who flew the North American X-15, an experimental spaceplane jointly operated by the United States Air Force and NASA. On September 28, 1965, he flew the X-15 to an altitude of 295,600 feet (90,100 m), thereby qualifying as an astronaut according to the United States definition of the boundary of space. However, this altitude did not surpass the Kármán line as defined by the FAI, the FAI-accepted boundary of 100 kilometres (62.1 mi).
Forrest Silas Petersen, , was a United States Navy aviator and test pilot. He was one of twelve pilots who flew the North American X-15, an experimental spaceplane jointly operated by the Air Force and NASA.
The Douglas Skystreak was an American single-engine jet research aircraft of the 1940s. It was designed in 1945 by the Douglas Aircraft Company for the U.S. Navy Bureau of Aeronautics, in conjunction with the National Advisory Committee for Aeronautics (NACA). The Skystreak was a turbojet-powered aircraft that took off from the ground under its own power and had unswept flying surfaces.

Herbert Henry Hoover was an American NACA experimental test pilot who, on March 10, 1948, became the first civilian ever and second man ever to break the sound barrier, a feat for which he was awarded the Air Medal "for meritorious achievement while participating in aerial flight." Hoover, with Howard Lilly by his side, flew the iconic orange Bell X-1 during this historic flight, and the craft sustained minor damage when the nose wheel failed to extend during landing. During his short career with NACA, Hoover completed more than a dozen supersonic flights.
