NASA's X-59 experimental jet breaks sound barrier in test of quiet supersonic flight
By
Joanna Thompson
Summary
NASA's experimental X-59 supersonic aircraft, developed with Lockheed Martin, broke the sound barrier for the first time on June 5, reaching Mach 1.1 (713 mph) at 43,400 feet during an 81-minute test flight from Edwards Air Force Base. The milestone advances the goal of "quiet supersonic" flight, where the sonic boom is reduced to a small thump.
