(CBS News) - Unmanned aerial vehicles, a key weapon in the hunt for terrorists overseas, are coming to America. In February, President Barack Obama signed a bill that opens U.S. airspace to thousands of these unmanned aircraft. Rep. John Mica, R-Fla., chairman of the House Transportation and Infrastructure Committee, thinks the FAA was dragging its feet on allowing domestic drones. The passed legislation will put 10,000 drones in the sky by 2017.
