In this Nov. 3, 2015, photo, a Predator drone owned by the U.S. Customs and Border Protection sits on the tarmac awaiting takeoff from the agency's Grand Forks Air Force Base operations in North Dakota. The unmanned aircraft is about the size of a business jet and can fly for at least 20 hours, but experienced pilots say it's a difficult plane to land. (AP Photos/Dave Kolpack) ** FILE **
