SpaceShipOne fifth drop test

Scaled Composites completed the fifth test flight of SpaceShipOne on November 14th at the Mojave Civilian Test Flight Facility.

Objectives: The fifth glide flight of SpaceShipOne. New pilot checkout flight. Stability and control testing with the new extended horizontal tails. Tests included stall performance at aft limit CG and evaluation of the increased pitch and roll control authority. Other objectives included additional testing of the motor controller (MCS) and handling qualities in feathered flight.

Results: Launch conditions were 47,300 feet and 115 knots. Satisfactory stability and control at aft limit CG. A notable improvement in control power, particularly in roll. Handling qualities into and out of feather remained excellent with good nose pointing ability. Adjusted landing pattern altitudes resulted in a touchdown at the targeted runway aim-point.

There is as yet no indication when they will be ready for the first in-flight engine ignition test. It is conceivable this might be carried out next month on the date of the First Flight anniversary. As for the first suborbital flight, I certainly expect to see it before next summer. I do not know the status of their launch license filing beyond the gossip of last summer when they most likely decided to start the process, and that is likely a limiting factor on the launch date.
