NASA has unveiled a new supersonic aircraft, the X-59 Quesst. This prototype has been in the works since 2016, but now enough work has finally been done that NASA believes it is ready to be shown to the world.
The name stands for Quiet Super Sonic Technology, hence the second s. It is designed to reach a top speed of Mach 1.4, which is about 1,488 mph. The most interesting thing about this superfast aircraft is that although it breaks the sound barrier, it does so without making a huge noise.
That means the X-59 Quesst can be used even in densely populated areas. NASA hopes that one day this technology can be used in commercial flights, allowing passengers to soar over the world at incredible speeds.
