NASA’s X-59 quiet supersonic research aircraft has completed a key milestone by flying with its wheels retracted. This phase included the aircraft's highest and fastest flights so far, expanding its operational range as it advances toward supersonic capabilities.

Upcoming tests will evaluate the aircraft’s control performance, structural dynamics, and operations of systems including hydraulics, fuel, avionics, and landing gear. Another focus will be the eXternal Vision System, which uses cameras to provide a forward view inside the cockpit, replacing the traditional forward windshield.

The X-59 is part of NASA’s Quesst mission, aiming to demonstrate technologies that enable supersonic flight without loud sonic booms, potentially transforming future commercial supersonic travel.
