lowest loss rate of any Allied bomber. In addition, MacDill Field provided transitional training in the B-17 Flying Fortress. The first Eighth Air Force Flying Fortress groups were trained at MacDill prior to their deployment to England in the summer of 1942. Also, the command and control organizations for Eighth Air Force were organized and equipped at MacDill in 1942. Heavy bomber training ended in July 1942, as the B-17 group training mission was reassigned to II Bomber Command and moved to the Midwest and Western states. Estimates of the number of crew members trained at the base during the war vary from 50,000 to 120,000, with as many as 15,000 troops stationed at MacDill Field at one time. A contingent of Women's Army Corps troops arrived in 1943. The base provided various forms of entertainment, including band concerts, live performers, and a movie theater. Two films were made in Tampa during World War II with wartime themes: A Guy Named Joe (1943) starred Spencer Tracy and had scenes shot at MacDill; Air Force (1943) starred John Garfield and had scenes shot at Drew Field. In the latter film, MacDill-based B-26s were painted as Japanese bombers, and although the entire Tampa Bay area defenses were alerted to this, the U.S. Coast Guard still shot at the planes as they flew over the Gulf. In late 1943, when Second Air Force began transitioning to B-29 Superfortress training, the B-17 mission returned to MacDill, which continued through the end of World War II. As a result, the 21st Bombardment Group was disbanded on 10 October 1943, and the OTU that performed the B-17 training, the 488th Bombardment Group (Heavy), was activated in November 1943 with four bombardment training squadrons. In an administrative reorganization by HQ Army Air Force on 1 May 1944, numbered training units in the Zone of the Interior (ZI) (continental United States) were redesignated as "Army Air Force Base Units". At MacDill, the 488th Bomb Group was redesignated as the 326th Army Air Forces Base Unit (Heavy Bombardment) and B-17 training squadron tail codes were designated as "H, J, K, and L". Beginning in January 1944, the 11th Photographic Group used MacDill for its mission of photographic mapping in the US, and sent detachments to carry out similar operations in Africa, the CBI theater, the Near and Middle East, Mexico, Canada, Alaska, and the Caribbean. The unit flew a
