NASA's X-59 is an experimental supersonic aircraft designed to create a quiet sonic thump rather than a loud boom, aiming to enable supersonic commercial flights over land. During its second flight near the Armstrong Flight Research Center, the aircraft experienced an early landing caused by a false positive warning from incorrectly installed instrumentation.
The flight lasted just minutes, yet NASA collected valuable information to support the planned envelope expansion testing of speed and altitude in coming flights. This campaign will gradually push the X-59 to supersonic speeds to demonstrate performance and airworthiness as part of the Quesst mission.
