In October 2004, Burt Rutan's Scaled Composites claimed the $10 million Ansari X Prize when their spacecraft SpaceShipOne achieved suborbital flight--the first private organization to do so. Now, eight and a half years later, the commercial version of SpaceShipOne, Virgin Galactic's SpaceShipTwo, achieved supersonic speeds after its pilots successfully fired the rockets at 47,000 feet. The video speaks for itself.
