In this historical photo from the U.S. space agency, a Langley researcher ponders the future, in mid-1927, of the Sperry M-1 Messenger, the first full-scale airplane tested in the Propeller Research Tunnel. Standing in the exit cone is Elton W. Miller, Max M. Munk's successor as chief of aerodynamics.

The National Advisory Committe on Aeronautics (NACA) was a precursor to NASA. NACA was created by Congress in 1915.
