Happened to me in Chicago - the Friday afternoon prior to Memorial Day. Air Force One landed at O’Hare, the Zero had to leave by helicopter, so it shut down the airport for about an hour - we sat on the tarmac for the entire time, just missing being able to take off. Passengers sitting next to me missed their connection to London - they weren’t big Obama fans that day.
Close a runway - don’t need the entire airspace around the city.
