This an excerpt from www.xprize.com QUOTE SPACESHIPONE BREAKS THE SOUND BARRIER .... At motor shutdown, 15 seconds after ignition, SpaceShipOne was climbing at a 60-degree angle and flying near 1.2 Mach (930 mph). Brian then continued the maneuver to a vertical climb, achieving zero speed at an altitude of 68,000 feet. He then configured the ship in its high-drag "feathered" shape to simulate the condition it will experience when it enters the atmosphere after a space flight. UNQUOTE Look at those feathers!
