The most widely used type was the Waco CG-4A, which was first used in the invasion of Sicily in July 1943 and participated in the D-Day assault on France on 6 June 1944, and in other important airborne operations in Europe, including Operation Market Garden in September 1944 and the crossing the Rhine in March 1945, and in the China-Burma-India Theater. The CG-4A was constructed of a metal and wood frame covered with fabric, manned by a crew of two and with an allowable normal cargo load of 3,710 lb, allowing it to carry 13 combat-equipped troops or a jeep or small artillery piece. The CG-10 could hold 10,850 lb of cargo, such as two howitzers, at a time. The final glider mission of the war was at Luzon on 23 June 1945. By the end of the war, the United States had built 14,612 gliders of all types and had trained over 6,000 glider pilots. The designs of the Waco Aircraft Company were also produced by a wide variety of manufacturers including Ford Motor Company and Cessna Aircraft Company as well as furniture, piano and coffin manufacturers.
