Last year, NASA issued Lockheed Martin a nearly $ 250 million contract to develop an aircraft that could reach supersonic speed without creating the deafening volume that comes with breaking the sound barrier. In November, the armed forces announced that its experimental supersonic aircraft had entered the production.
Lockheed's X-59 Quiet Supersonic Technology aircraft designed to cruise 55,000 feet and reach a speed of approx. 940 miles per hour is expected to create a noise level similar to the sound of a door closure.
Current rules prohibit commercial supersonic aircraft from land-based operation. New companies like Boom Supersonic are trying to make use of the technology of transoceanic routes with the support of investors such as Richard Branson and Japan Airlines.

But Lockheed Martin and NASA want to advance technology through noise reduction to reverse regulations. The new test plan is designed to return supersonic passenger flights to land-based routes. The last such flight was at Concorde in October 2003.
