An X-47B pilot-less drone combat aircraft is pictured as it flies over the aircraft carrier, the USS George H. W. Bush, after being launched from the ship in the Atlantic Ocean off the coast of Virginia, May 14, 2013. The U.S. Navy made aviation history on Tuesday by catapulting an unmanned jet off an aircraft carrier for the first time, testing a long-range, stealthy, bat-winged plane that represents a jump forward in drone technology.
