NASA's X-59 Quiet Supersonic Aircraft Prepares for Second Test Flight

NASA's X-59 QueSST aircraft completed engine testing at Armstrong Flight Research Center and is preparing for its second test flight after its maiden flight in October 2025. Built with Lockheed Martin, the experimental aircraft is designed to break the sound barrier without producing thunderous sonic booms, potentially enabling commercial supersonic overland flight. Success could reshape FAA regulations banning supersonic flight over land.
