Push-pull configuration

In contrast, both the World War II-era Dornier Do 335 and the early 1960s-designed French Moynet M 360 Jupiter experimental private plane had their pusher propeller behind the tail.

The advantage it provides is the ability to mount two propellers on the aircraft's centreline, thereby avoiding the increased drag that comes with twin wing-mounted engines.

In contrast, a conventional twin-engine aircraft will yaw in the direction of the failed engine and become uncontrollable below a certain airspeed, known as VMC.

Examples of past military applications include the aforementioned Siemens-Schuckert DDr.I twin-engined triplane and the Gotha G.VI, with its engines mounted on the front and rear ends of two separate fuselages.

Near the end of World War II, the German Dornier Do 335 push-pull twin-engined, Zerstörer-candidate heavy fighter featured explosive charges to jettison the rear propeller and dorsal tailfin, a manually-jettisonable main canopy, as well as an ejection seat.
