The U.S. Federal Aviation Administration (FAA) closed some airspace in Montana on Saturday night for Defense Department activities.

The temporary flight restriction from the FAA was issued for flights in an area about 50 by 50 nautical miles above Havre, Montana, near the Canadian border, the agency said. The notice reclassified the area as “national defense airspace.”
