This artist's impresion shows a Boeing concept for a next-generation supersonic airliner which would fly at 2.4 times the speed of sound. A new supersonic airliner could travel long distances inabout half the itme needed for the same trip on a subsonic airliner. NASA's High-Speed Research Program is an ongoing project to develop the key technologies that would make such a plane environmentally safe and economically feasible.
