NASA starts wind tunnel tests for its quiet supersonic jet

From Engadget: 

NASA's plans for a quiet supersonic jet, the QueSST, just became tangible: the agency and Lockheed Martin have started wind tunnel tests for the future X-plane. It's a scale model at this stage, but it will be subjected to winds as high as Mach 1.6 (950MPH) to gauge both its aerodynamic performance as well as parts of its propulsion system. The tests should run until the middle of 2017.
