The Smithsonian example is a BT-13A, AAF serial number 41-22124. Vultee delivered it to the Army on June 3, 1942. This trainer flew from many bases: Maxwell Field, Alabama (June 1942), Starkville, Mississippi (September 1942), Bates Field, Alabama (October 1942), McBride, Missouri (March 1943), Hunter Field, Georgia (May 1943), Wright Field, Ohio (June 1943), and Clinton County Army Air Field, Ohio (July 1943). Clinton County was the Glider Branch Engineering and Experiment Base and the NASM BT-13A served there as part of the disabled fighter tow system test program. When the war ended, 41-22124 moved to Freeman Field, Indiana, a collection point for aircraft set aside for the future National Air Museum. Its final flight brought it to a storage facility at Park Ridge, Illinois, on May 21, 1946, logging nearly 1,400 flight hours. The Smithsonian accepted it from the Air Force on June 15, 1960.
