The X-59, short for X-59 Quiet SuperSonic Technology (QueSST), is an experimental aircraft being developed by four NASA research centers, General Electric, and Lockheed Martin. The X designation is given to US aircraft and rockets that are used to test new technologies. The X-59 will test technology that will allow the aircraft to fly faster than the speed of sound over land and Reduce the loud sonic boom to a quiet thump. It is NASA’s first piloted experimental aircraft since the X-57 in 2016. Currently, commercial airlines can’t fly faster than the speed of sound over land because it would create a very loud sonic boom. Available in 1/60 scale. See the chart below for dimensions.
