NASA’s experimental supersonic jet edges toward first test flight
NASA’s experimental X-59 Quiet SuperSonic Technology (QueSST) plane is gearing up for its first test flight sometime this year. As its name suggests, the plane is trialing technology that dampens the sound of the very loud sonic boom that occurs when an aircraft breaks the sound barrier. The X-59 is supposed to reduce the sudden noise to a quieter “sonic thump,” so it could pave the way for supersonic passenger flights over the continental U....
