NASA's X-59 experimental supersonic plane has reached a major milestone, flying in Mach 1.4 speed and an altitude of 55,000 feet, the conditions required for the aircraft to make future flights critical to its mission.
NASA said that the X-59 still has months of performance testing ahead, but after those are complete, its Quesst mission will fly the aircraft over several U.S. communities to collect data on public perception of the quiet sonic thump it will make at supersonic speeds. Those community overflights will include flights at Mach 1.4, or about 924 mph, and 55,000 feet.
