The Federal Aviation Administration (FAA) announced on Tuesday that it has closed airspace over part of Montana after an unidentified flying object was spotted in the area.
The FAA said it was taking the precautionary measure to ensure the safety of those in the area and to investigate the mysterious object.
The airspace was closed between Missoula and Bozeman, Montana, and the FAA said flights in the area were diverted or canceled.
The closure of the airspace prompted an investigation by the Department of Defense and the FAA said it was working with the department to determine the cause of the unidentified object.
On Wednesday, the FAA said the airspace had been reopened after the Department of Defense activities were completed.
The FAA said the object was a false alarm and that the military had determined it posed no threat.
The closure of the airspace has caused a stir in the state, with Montana Senator Steve Daines demanding answers from the Pentagon about why the airspace was closed and for how long.
The Pentagon has yet to respond to the Senator’s inquiries and it remains unclear why the airspace was closed and for how long.
