Cessna 337 Skymaster

The Cessna Skymaster is an American twin-engine civil utility aircraft with a push-pull layout: one engine sits in the nose and one at the rear of a pod fuselage, with twin booms carrying the tail. Because the combined thrust acts along the centreline, an engine failure does not yaw the aircraft toward the dead engine. The fixed-gear Model 336 first flew on 28 February 1961 and entered production in May 1963, and the larger Model 337 Super Skymaster, with retractable gear and more powerful engines, followed in February 1965, with a turbocharged T337 in 1966 and a pressurized P337G in 1973. Cessna built 2,993 Skymasters of all variants, including 513 military O-2 versions. American production ended in 1982 but continued in France under Reims.
