Unmanned drone aircraft based at Grand Forks Air Force Base are set to start patrolling the Canadian border.
A ceremony to mark the launch was set for Monday at the base. The military facility is one of five outposts that will be part of the U.S. Customs and Border Protection unmanned aircraft program.
The Predator drone can detect a moving person from 7 miles away. Information gathered by the drones will be transmitted back to operators, who will contact border agents.
