Flight 16P of SpaceShipOne was a spaceflight in the Tier One program that took place on September 29, 2004. It was the first competitive flight in the Ansari X PRIZE competition to demonstrate a non-governmental reusable crewed spacecraft, and is hence also referred to as the X1 flight. A serious roll excursion occurred during boost, so the flight did not achieve the expected altitude. However, it exceeded 100 km altitude, making it a successful X PRIZE flight.
