flag NASA's X-59 Quesst successfully flew for the first time, testing quiet supersonic flight technology.

flag NASA’s X-59 Quesst, a Lockheed Martin-built experimental aircraft designed to produce a quiet sonic boom, successfully completed its first flight on October 28, 2025, from Palmdale, California, to Edwards Air Force Base. flag Piloted by NASA’s Nils Larson, the 1-hour, 7-minute flight tested basic handling at subsonic speeds up to 250 knots and 12,000 feet, gathering data on flight control, avionics, and structural integrity. flag The X-59’s unique shape aims to reduce sonic booms to a soft thump, supporting efforts to revise FAA regulations banning overland supersonic flight. flag Future phases will expand speed and altitude, validate acoustic performance, and assess public response, with updated noise standards expected by 2030. flag The aircraft will remain based at NASA’s Armstrong Flight Research Center.
