NASA’s new X-59 supersonic research aircraft is poised to crack the most vexing problem of commercial faster-than-sound travel: Sonic boom. The unique shape of the aircraft manages shockwave formation and is anticipated to reduce the window-rattling noise of sonic booms to a thump no louder than the slamming of a car door. If it works, a new generation of supersonic commercial airliners may be free of current FAA restrictions over supersonic operations over populated areas. * * *Want to watch this podcast as a video?
