John Michael Riebe (8 May 1921 – 21 February 2011) was an American aeronautical engineer and inventor who contributed to the early designs of flight surfaces.
Other significant contributions included being project engineer in the development of the Grumman F8F fighter, involvement with short takeoff and landing projects for airline terminals, and work on control systems for rockets, flying boats, Delta wings and powered lift systems.
He performed tests in the numerous wind tunnels of the National Advisory Committee for Aeronautics' Langley Memorial Aeronautical Laboratory in Langley Field, Virginia (now NASA's Langley Research Center in Langley Air Force Base, Virginia), where he was employed.
Many of the tests he performed, as well as the resulting data and reports, were classified at the time because they were wartime reports, but have been since declassified and available to the general public.
