Cessna Skymaster
 The Cessna Skymaster is a United States twin-engine civil utility aircraft built in a push-pull configuration. Its engines are mounted in the nose and rear of its pod-style fuselage. Twin booms extend aft of the wings to the vertical stabilizers with the rear engine between them. The horizontal stabilizer is aft of the pusher propeller mounted between and connecting the two booms. The combined tractor and pusher engines produce 'centerline' thrust and a unique sound.
