People look up into the sky to watch the historic flight of SpaceShipOne at the Mojave Airport in California, June 21, 2004. SpaceShipOne, the first privately-funded rocket plane, flew to outer space and into history books on Monday after blasting 100 kilometers (62 miles) above the earth, marking the world's first commercial space flight. The flight marked the first time that a non-government spacecraft reached the altitude considered to be the boundary between earth's atmosphere and outer space. REUTERS/Mike Blake MB/GN
