SpaceShipOne is a rocket-powered aircraft with sub-orbital spaceflight capability at speeds of up to 3,000 ft/s (900 m/s). Its unique design features a “feathering” atmospheric reentry system where the rear half of the wing and the twin tail booms fold 70 degrees upward. Watch the video to understand the function of this unique design. Also, learn how you can do a simple experiment at home to see the rationale behind this design.
