Mission Detroit was a pre-dawn glider-borne combat assault in the American airborne landings in Normandy, made by elements of the U.S. 82nd Airborne Division on the early morning of June 6, 1944, during World War II. It was part of Operation Neptune, the assault portion of the Allied invasion of Normandy, Operation Overlord. Originally slated to be the main assault for the 82nd Airborne, the glider operation instead became the first reinforcement mission after the main parachute combat assault, Mission Boston. The landing zone for mission Detroit was near Sainte-Mère-Église, to the west of Utah Beach.
