Scaled Composites reached new heights with the third powered flight of SpaceShipOne. Altitude of 211,400 ft. (almost 41 miles) and velocity of Mach 2.5 with a 55 second hybrid burn.
Launch conditions were 46,000 feet and 120 knots. Motor light off occurred 10 seconds after release and the vehicle boosted smoothly to 150,000 feet and Mach 2.5. Subsequent coast to apogee of 211,400 feet. During a portion of the boost, the flight director display was inoperative, however the pilot continued the planned trajectory referencing the external horizon. Reaction control authority was as predicted and the vehicle recovered in feather experiencing 1.9M and 3.5Gs. Feather oscillations were actively damped by the pilot and the wing was de-feathered starting at 55,000 feet. The onboard avionics was re-booted and a smooth and uneventful landing made to Mojave.
The next flight should break the 50 mile mark and probably the 100 km (62 mile) mark. The X-Prize should be claimed by Scaled Composites by July 4.
