The good old Concorde had a problem which placed a serious ristriction on its service. It generates a huge sonic blast of more than 120 db on the ground when cruising. This fact made FAA banned the Concorde from doing cross continet flight. At the same time, a lot of countries banned Concorde as well. In order to seek solution to this problem, NASA and Lockheed initiated this QueSST program. When supersonic cruising, this plane would only generate about 70db of noise. This plane is now under construction and we may see it fly someday. This build is approximately 1 to 1 in scale, weight and wing loading. But the drag seems a bit broken so it can only fly 781mph at 52000ft. AG8 gyro. Hope you enjoy! And as always, if you wish to know more, google this title.
