Pentagon Pushes FAA To Open U.S. Airspace To Drones | With the U.S. withdrawal from Iraq and the completion of U.S. combat operations in Afghanistan next year, a large portion of the Pentagon’s fleet of 7,500 combat drones will return to the U.S. The Pentagon is urging the FAA to open U.S. airspace to the unmanned aircraft. Currently, the FAA doesn’t allow drone aircraft in U.S. airspace without a special certificate but the Pentagon hopes to station drones at various military bases for pilot training and firefighting. The FAA has said drone aircraft are generally not allowed in U.S. airspace because they don’t have adequate “detect, sense and avoid” technology to prevent midair collisions.
