context_page_description: SpaceShipOne is an experimental air-launched rocket-powered aircraft with sub-orbital spaceflight capability at speeds of up to 900 m/s, using a hybrid rocket motor. The design features a unique "feathering" atmospheric reentry system where the rear half of the wing and the twin tail booms folds 70 degrees upward along a hinge running the length of the wing; increasing drag while remaining stable. SpaceShipOne completed the first crewed private spaceflight in 2004. That same year, it won the US$10 million Ansari X Prize and was immediately retired from active service. Its mother ship was named "White Knight". Both craft were developed and flown by Mojave Aerospace Ventures, which was a joint venture between Paul Allen and Scaled Composites, Burt Rutan's aviation company. Allen provided the funding of approximately US$25 million.
  Rutan has indicated that ideas about the project began as early as 1994 and the full-time development cycle time to the 2004 accomplishments was about three years. The vehicle first achieved supersonic flight on December 17, 2003, which was also the one-hundredth anniversary of the Wright Brothers' historic first powered flight.
context_section_description: SpaceShipOne was developed by Mojave Aerospace Ventures (a joint venture between Paul Allen and Scaled Composites, Burt Rutan's aviation company, in their Tier One program), without government funding. On June 21, 2004, it made the first privately funded human spaceflight. On October 4, it won the US$10 million Ansari X Prize, by reaching 100 kilometers in altitude twice in a two-week period with the equivalent of three people on board and with no more than ten percent of the non-fuel weight of the spacecraft replaced between flights. Development costs were estimated to be US$25 million, funded completely by Paul Allen.
  During its test program, SpaceShipOne set a number of important "firsts", including first privately funded aircraft to exceed Mach 2 and Mach 3, first privately funded crewed spacecraft to exceed 100km altitude, and first privately funded reusable crewed spacecraft.
  SpaceShipOne was registered with the FAA as N328KF. N is the prefix for US-registered aircraft; 328KF was chosen by Scaled Composites to stand for 328 kilofeet (about 100 kilometers), the officially designated edge of space. The original choice of registry number, N100KM, was already taken. N328KF is registered as a glider, reflecting the fact that most of its independent flight is unpowered.
  SpaceShipOne's first flight, 01C, was an uncrewed captive flight test on May 20, 2003. Glide tests followed, starting with flight 03G on August 7, 2003. Its first powered flight, flight 11P, was made on December 17, 2003, the 100th anniversary of the first powered flight.
  On April 1, 2004, Scaled Composites received the first license for suborbital rocket flights to be issued by the US Office of Commercial Space Transportation. This license permitted the company to conduct powered test flights over the course of one year. On June 17, 2004, under the leadership of airport CEO Stuart O. Witt, Mojave Airport reclassified itself as the Mojave Air and Space Port.
  Flight 15P on June 21, 2004, was SpaceShipOne's first spaceflight, and the first privately funded human spaceflight. There were a few control problems, but these were resolved prior to the Ansari X PRIZE flights that followed, with flight 17P to 112 km on October 4, 2004, winning the prize.
  The SpaceShipOne Team was awarded the Space Achievement Award by the Space Foundation in 2005.
