Military officials shot down an object over Lake Huron, just hours after airspace was closed over Lake Michigan, U.S. officials confirm to ABC News. Earlier this afternoon, the FAA said it was closing airspace over the northern part of Lake Michigan to “support Department of Defense activities,” but opened the airspace shortly after the closure. Just before 4 p.m., officials confirmed to ABC News that the military shot an unidentified object over Lake Huron.
