The first qualifying flight for the Ansari X Prize becomes a dangerous one for pilot Mike Melvill, as the experimental spacecraft SpaceShip One begins a rapid roll after its rocket engine ignites, sending the vehicle on a twisty trajectory into suborbital space. The vehicle reaches just under Mach 3, and still passes the altitude of 100 kilometers necessary to be considered a space flight (and to be considered a contender for the X Prize), but SpaceShip One must repeat the feat to win the $10,000,000 prize for launching the first privately funded spacecraft.
