Dave Richardson, director, Air Vehicle Design and Technologies, Lockheed Martin Skunk Works, speaks after the announcement that Lockheed Martin won the contract to develop the first X-plane at a briefing, Tuesday, April 3, 2018 at NASA Headquarters in Washington. This new experimental aircraft will cut cross country travel times in half by flying faster than the speed of sound without creating a sonic boom, enabling travel from New York to Los Angeles in two hours.
