The X-59 Quiet SuperSonic Technology, or QueSST, experimental aircraft is approximately 100 feet long and is designed to fly at Mach 1.4 (925 mph). The aircraft is a part of the Low-Boom Flight Demonstration mission, which has two goals: 1) design and build NASA's X-59 QueSST research aircraft with technology that reduces the loudness of a sonic boom to of a gentle thump to people on the ground; and 2) fly the X-59 over select U.S. communities to gather data on human responses to the sound generated during supersonic flight and deliver that data set to U.S. and international regulators.
