The quickest and easiest way to have the airspace in Montana reopened by the U.S. Federal Aviation Administration (FAA) after a radar anomaly prompted a brief shutdown was for the U.S. military to detect that no threatening object was present. The FAA closed and then reopened the airspace in Montana after temporarily barring flights in an area about 50 by 50 nautical miles (93 by 93 km). Representative Matt Rosendale, a Montana Republican, said on Twitter he was in contact with the U.S. military “and monitoring the latest issue over Havre and the northern border”. He said the issue was because of “an object that could interfere with commercial air traffic — the DOD will resume efforts to observe and ground the object in the morning”. The U.S. military then detected that no threatening object was present, allowing for the airspace to be reopened.

The US Federal Aviation Administration (FAA) temporarily closed airspace over part of Montana to investigate a "radar anomaly" that was detected by the North American Aerospace Defense Command (NORAD). The anomaly was spotted on radar and a fighter jet was sent up to investigate. After the investigation, the airspace was reopened.
