NASA X-59 Quiet Supersonic Jet's Second Test Flight Ends Early After In-Flight Anomaly

The second test flight of NASA's X-59 Quesst quiet supersonic research aircraft ended early after an in-flight anomaly. The X-59 is designed to demonstrate that supersonic flight can produce a quiet 'thump' rather than a disruptive sonic boom, potentially opening commercial supersonic flight over land. NASA has not detailed the specific issue but confirmed the aircraft landed safely. The program aims to provide data that could lead to lifting the FAA's ban on overland supersonic commercial flight.
