Robert R. Gilruth of the Langley Flight Research Division, prompted by the need for an experimental method of gathering aerodynamic data at transonic speeds, conceived the wing-flow method (utilizing the transonic-airflow field over the top surface of the wing of a high-speed subsonic airplane, usually a P-51 fighter, as a "flying wind tunnel" for testing small semispan wing and airplane models).

First positive identification of German turbojet interceptors used against Allied bombers. RAF formed first Meteor jet squadrons for use against V-1's.
