Dwight Henry Bennett (November 19, 1917 – July 10, 2002) was an aeronautical engineer and one of the early developers of the control configured vehicle (CCV) concept.
 He won the Wright Brothers Medal in 1972 with R. P. Johannes for the paper "Combat Capabilities and Versatility Through CCV", discussing its applications.
V. Ralph Pruitt (born July 31, 1936) was an engineer at McDonnell Douglas who won the Wright Brothers Medal in 1974 with Michael J. Wendl, Gordon G. Grose, and J. L. Porter for a paper discussing future aircraft designs that integrate fly-by-wire controls with engine inlets/nozzles and advanced pilot displays.
Homer J. Wood was an engineer at Garrett AiResearch, who did pioneering work in gas turbine engines for aircraft applications.
 He won the Wright Brothers Medal in 1949 with Frederick Dallenbach for a paper discussing auxiliary turbines to supply pneumatic power for aircraft based on the Garrett GTC43/44 and GTP70 units.
 Wood went on to design the GTC85, one of the most widely used auxiliary power units in commercial and military aviation.
McDonnell Douglas was a major American aerospace manufacturing corporation and defense contractor formed by the merger of McDonnell Aircraft and the Douglas Aircraft Company in 1967.
 Between then and its own merger with Boeing in 1997, it produced a number of well-known commercial and military aircraft such as the DC-10 airliner and F-15 Eagle air-superiority fighter.
Kermit Van Every (March 5, 1915 – November 20, 1998) was a noted American aeronautical engineer best known for his work in the area of very high speed flight.
 He was a fellow of the American Institute of Aeronautics and Astronautics and had the unusual distinction of receiving the Wright Brothers Medal twice, in 1948 and 1958.
Richard V. Rhode (March 2, 1904 – November 13, 1994) was an early aeronautical engineer at Langley Memorial Aeronautical Laboratory, who researched aerodynamic loading.
 He was awarded the Wright Brothers Medal in 1937 for this work.
 He continued doing secret aerodynamics-related research work during World War II, the results of which were later declassified.
Michael John Wendl (born June 6, 1934) is an engineer who worked at the McDonnell-Douglas Corporation, mainly in the area of aerospace control.
 He is noted primarily as one of the early developers of terrain following technology and a proponent of incorporating energy management theory into the design of fighter aircraft.
 He won the Wright Brothers Medal in 1974 with Ralph Pruitt, Gordon G. Grose, and J. L. Porter for a paper discussing future aircraft designs that integrate fly-by-wire controls with engine inlets/nozzles and advanced pilot displays.
Robert P. Johannes (born May 1934 in Moline, Illinois) is an aeronautical engineer noted primarily as one of the developers of the control configured vehicle (CCV) concept.
 He won the Wright Brothers Medal in 1972 with Dwight Henry Bennett for the paper "Combat Capabilities and Versatility Through CCV" discussing its applications.
William Littlewood was an aeronautical engineer noted for his contributions to the design and operational requirements of transport aircraft.
 He graduated from Cornell University in 1920 and was the only person to preside over both SAE and AIAA, two of the main aerospace professional organizations.
 He won the Wright Brothers Medal in 1935 for a paper on the operational requirements of transports and is memorialized by the SAE "William Littlewood Memorial Lecture".
Gordon G. Grose (born March 1925) was an engineer at the McDonnell-Douglas Corporation.
 He won the Wright Brothers Medal in 1974 with Michael J. Wendl, J. L. Porter, and Ralph Pruitt for a paper discussing future aircraft designs that integrate fly-by-wire controls with engine inlets/nozzles and advanced pilot displays.
