Push-Pull Aircraft

A few planes were built with one pro­peller at the front and another propeller at the back. They were called push-pull aircraft. The German Dornier Do-335 of the 1940s was a push-pull fighter. With one engine and propeller at the front and another at the back, it was very fast. The push-pull layout has been used in experimental aircraft, too. Voyager, the first plane to fly around the world with­out landing anywhere or refueling on the way, was a push-pull plane. It had an engine and propeller in its nose and another set in its tail. Its 25,000-mile (about 40,250-kilometer) flight took nine days in 1986.
