Elbert Leander "Burt" Rutan (born June 17, 1943 in Estacada, Oregon) is an American aerospace engineer noted for his originality in designing light, strong, unusual-looking, energy-efficient aircraft. He is most famous for his design of the record-breaking Voyager, which was the first plane to fly around the world without stopping or refueling, and the suborbital rocket plane SpaceShipOne, which won the Ansari X-Prize in 2004.
SpaceShipOne became the first private/privately funded craft to reach space in June of that year and win the Ansari X Prize a few months later on October 4. SpaceShipOne completed 2 flights within 2 weeks, flying with the equivalent weight of 3 persons and doing so while reusing at least 80% of the vehicle hardware.
