At 7:55 AM PDT this Monday, the Scaled Composites SpaceShipTwo (SST) attained a peak velocity of Mach 1.2 at an altitude of 55,000 feet (nearly 17 km) above the Mohave Desert with a 16-second burn of its 30-ton thrust rocket engine. Piloted by Mark Stucky and Mike Alsbury with an assist from Dave Mackay in the mother bird White Knight Two, this flight marks a stepping-off point for commercial manned spaceflight.
