In March 1945, B-29 No. 44-69972, now known as “Doc,” was delivered to the U.S. Army Air Corps. About five months later another B-29 was used to drop two atomic bombs on Japan, eventually leading to Japan’s surrender and the end of World War II.
In July 1951, Doc was assigned to radar calibration duty, along with a few other B-29s. The squadron was known as the “Seven Dwarfs.” In May 1955, Doc was assigned to target-towing duty and one year later, Doc and the rest of its squadron became targets for bomb training at China Lake, California.
