Milton Orville Thompson (usually referred to as Milt Thompson) (4 May 1926 – 6 August 1993) was a NASA research pilot who was selected as an astronaut for the United States Air Force X-20 Dyna-Soar program in April 1960. After the Dyna-Soar program was cancelled on 10 December 1963, he remained a NASA research pilot, and went on to fly the X-15 rocket plane. He became Chief Engineer and Director of Research Projects during a long career at the NASA Dryden Flight Research Center.

Early life

Born in Crookston, Minnesota, on 4 May 1926, Thompson began flying with the U.S. Navy as a pilot trainee at age 19. He served with duty in China and Japan.

Following six years of active naval service, Thompson entered the University of Washington, in Seattle, Washington. He graduated in 1953 with a Bachelor of Science degree in Engineering. He remained in the Naval Reserves during college, and continued flying, in Navy aircraft and in crop dusters and forest-spraying aircraft.

After college, Thompson became a flight test engineer for the Boeing Aircraft Company in Seattle. During his two years at Boeing, he flew on the sister aircraft of Dryden's B-52B air-launch vehicle.

Test pilot

Thompson was hired as an engineer at the flight research facility on 19 March 1956, when it was still under the auspices of the NACA. He became a research pilot in January 1958.

On 16 August 1963, Thompson became the first person to fly a lifting body, the lightweight NASA M2-F1. The plywood and steel-tubing prototype was flown as a glider after being released from an R4D tow plane. He flew it a total of 47 times, and also made the first five flights of the all-metal Northrop M2-F2 lifting body, beginning 12 July 1966.

Lifting bodies were wingless vehicles designed to generate lift and aerodynamic stability from the shape of their bodies. They were flown at Dryden to study and validate the concept of safely maneuvering and landing a low lift-over-drag vehicle designed for reentry from space. Data from the program helped in the development of the Space Shuttles.

Thompson was also one of the 12 NASA, Air Force, and Navy pilots to fly the X-15 rocket-powered research aircraft between 1959 and 1968. He began flying X-15s on 29 October 1963, only 74 days after his first Lifting Body flight. He flew the aircraft 14 times during the following two years, reaching a maximum speed of 3712 mph (Mach 5.48) and a peak altitude of 214,100 feet on separate flights.

The X-15 program provided a wealth of data on aerodynamics, thermodynamics, propulsion, flight controls, and the physiological aspects of high-speed, high-altitude flight.

Thompson was one of elite group of eight pilots who tested the paraglider research vehicle NASA Paresev.

In 1962 the US Air Force picked Thompson to be the only civilian test pilot to fly in the X-20 Dyna-Soar program that was intended to launch a human into Earth orbit and recover with a horizontal ground landing. The program was canceled before construction of the vehicle began.

Administrator

Thompson was also a member of NASA's Space Transportation System Technology Steering Committee during the 1970s. In this role he led the effort to design the Orbiters for power-off landings rather than increase weight with air-breathing engines for airliner-type landings. His committee work earned him NASA's highest award, the Distinguished Service Medal.

Thompson concluded his active flying career in 1967, becoming Chief of Research Projects two years later. In 1975 he was appointed Chief Engineer and retained the position until his death on 6 August 1993.

Awards

Thompson was a member of the Society of Experimental Test Pilots, and received the organization's Iven C. Kincheloe Award as the Outstanding Experimental Test Pilot of 1966 for his research flights in the M2 lifting bodies. He also received the 1967 Octave Chanute award from the American Institute of Aeronautics and Astronautics for his lifting-body research.

The National Aeronautic Association named Thompson as one of its 1990 "Elder Statesman of Aviation". This distinction, given since 1955, highlights contributions "of significant value over a period of years" in the field of aeronautics.

Thompson wrote several technical papers, was a member of NASA's Senior Executive Service, and received several NASA awards. His 1992 book, At the Edge of Space described the X-15 flight program. In 1993 he was inducted into the Aerospace Walk of Honor.

Thompson was married to Therese Beytebiere. They had 1 girl and 4 boys.

Thompson's parents were Peter Thompson and Alma T. Thompson; his siblings were Adeline, Fay and Janice.
