This time lapse video shows progress made on major sections of NASA’s X-59 Quiet SuperSonic Technology, or QueSST, aircraft at Lockheed Martin’s Skunk Works facility in Palmdale, California. Through X-59, NASA will demonstrate the ability to fly supersonic, or faster than the speed of sound, without producing a loud sonic boom typically heard on the ground below aircraft flying at such speeds, instead reducing it to a quiet thump. This may open the door to future faster-than-sound flight over land on a commercial level.
