US officials restricted the airspace over Lake Michigan on Sunday citing a potential new threat to national security but soon reopened the skies, as the United States and Canada respond to multiple air intrusions.
The Federal Aviation Administration (FAA) announced “temporary flight restrictions” over one of the Great Lakes along the US-Canada border, designating it as “national defense airspace,” one day after a similar closure over Montana led to the scrambling of US fighter jets.
The Montana closure was ordered over a “radar anomaly,” but no object was discovered.
