The Waco CG-4 was the most widely used American troop/cargo military glider of World War II. It was constructed of fabric-covered wood and metal and was crewed by a pilot and copilot. It had two fixed mainwheels and a tailwheel. The CG-4A could carry 13 troops and their equipment. Cargo loads could be a Jeep, a 75 mm howitzer, or a 1⁄4-ton trailer, loaded through the upward-hinged nose section.
