Unlike its privately funded predecessors, SpaceShipOne was actually manned, by a pilot and two passengers, when it flew to the edge of space in 2004. Developed by aerospace engineer Burt Rutan and funded by billionaire Microsoft co-founder Paul Allen, the suborbital space plane won the $10 million Ansari X Prize for launching three people—or their weight equivalent—into space twice within two weeks in a privately developed, reusable spacecraft. Where is SpaceShipOne currently on display?
