In the last two days, NASA's experimental supersonic aircraft, the X-59 QueSST (Quiet SuperSonic Technology), has moved a step closer to its first flight.

The "quiet" supersonic X-59 is now on the flight line, the area between the hangar and runway, according to images released by NASA.

Before flight, the team will need to conduct ground tests, including engine runs and taxi tests, to make sure it is safe for flight. NASA hasn't released a timeline for the first flight.

The X-59 has been in construction for more than two years. Its goal is to be able to fly supersonic, or faster than Mach 1 (767.2 mph), while reducing the sonic booms that defined previous supersonic aircraft like the Concorde, to a quiet thump.
