NASA and its industry partners are developing technologies for a next-generation supersonic passenger jet that would fly 300 passengers at more than twice the speed of sound. As envisioned, a high-speed civil transport would cross the Pacific or Atlantic in less than half the time of modern subsonic jets - at a ticket price less than 20 percent above comparable subsonic flights. Technology to make this possible is being developed as part of NASA's High-Speed Research program, supported by a team of major U.S. aerospace companies in a multi-year research program begun in 1990.
