NASA's experimental X-59 aircraft continues to make progress toward its first flight with a new successful round of testing. The X-59 "quiet" supersonic jet was designed to break the sound barrier ...

NASA's experimental aircraft, X-59, developed with Lockheed Martin, has entered the taxi test phase, moving closer to its first flight.

The X-59 jet, dubbed the “son of Concorde,” is one step closer to takeoff after the experimental aircraft taxied on a California runway at low speed using its own power for the first time on July 10, ...

Supersonic tunnel trials suggest the X-59’s shape can scatter shock waves, paving the way for hush-hush high-speed flight.

The X-59 is finally here. As NASA's newest X-plane, the X-59 is designed to break the sound barrier without the thunderous sonic booms that typically occur when aircraft go supersonic.
