"The drones have disappeared and the airport is open again," Deputy Police Inspector Jakob Hansen told reporters. "We didn't take the drones down," he added. The airport was closed for several hours before reopening early Tuesday, causing numerous delays and travel disruptions to 20,000 passengers, airport officials said. Hansen said police were cooperating with the Danish military and intelligence service to find out where the drones had come from.
