DARPA and Aurora Flight Sciences have begun building the first full-scale X-65 aircraft to demonstrate a new method of flight control that uses no external moving parts.
The X-65 is an experimental jet being developed by the Control of Revolutionary Aircraft with Novel Effectors (CRANE) program overseen by DARPA, (Defense Advanced Research Projects Agency), the Pentagon's research and development agency. Since the first aircraft were invented, they have been controlled by moving surfaces such as rudders, flaps, elevators and ailerons.
