Built as a Boeing B-17G-105-VE c/n 8693, the future Sally B was one of the last to be constructed by the Lockheed-Vega plant at Burbank, California. Accepted by the United States Army Air Force (USAAF) as 44-85784 on June 19 1945 it was too late to see war service, and was flown to Nashville for modifications. Converted for training purposes and re-designated TB-17G, it was based at Wright Field (now Wright-Patterson AFB), Ohio from November that year.
