'We're now one step closer to building an actual X-plane.'While Lockheed Martin has been working on the preliminary design, with hopes to move on to build the demonstrator, NASA has opened the door for other companies to submit their own designs as well, according to Aviation Week.
Lockheed’s research shows the design can maintain that sound level at commercial size and his team’s planned demo will be 94 feet long, have room for one pilot, fly as high as 55,000 feet, and run on one of the twin engines that power Boeing Co.’s F/A-18 fighter jet.

Its scale model for the Low Boom Flight Demonstration (LBFD) experimental plane was put through the 8-by 6-foot supersonic wind tunnel at NASA's Glenn Research Center last month, and the space agency has now completed the preliminary design review.
