The Vought F4U-4B "Corsair" Navy fighter. See also figures 3 and 17 of volume 4. This photograph is dated 7/18/51. The Vought F4U-4B was usually seen in a combat role, but as the NACA tail band suggests, this Corsair was used for research. The test work undertaken by this F4U included control rate investigation. Langley was the second research facility to use this Corsair. It came to Langley in 1950, from the Naval Air Test Center, Patuxent River, Maryland.
