NASA's Glenn Research Center dedicated a model of the hybrid wing body, a futuristic aircraft concept, on July 8, 2009. The center is testing parts of a new propulsion system that can be embedded in the wing of the airplane. Developed by NASA and Boeing, the plane is called a hybrid wing body because its wings and fuselage blend together in a triangular shape. The concept could revolutionize air travel because of its potential to increase fuel efficiency, while reducing noise and emissions.
