"Elbert Leander \"Burt\" Rutan (born June 17, 1943) is an American aerospace engineer noted for his originality in designing light, strong, unusual-looking, energy-efficient aircraft. He designed the record-breaking Voyager, which was the first plane to fly around the world without stopping or refueling, and the sub-orbital spaceplane SpaceShipOne, which won the Ansari X-Prize in 2004 for becoming the first privately funded spacecraft to enter the realm of space twice within a two-week period."@en . . .
