The first alarm came in at 21.30 after several people saw drones flying next to the airport. It was not until an hour later that the police could confirm that drones had been spotted, then inside the airport area.
The airspace around the airport was closed and about 20 flights were affected.
Air traffic to and from Munich airport is reduced every evening at 10 to minimize disturbances for residents in the vicinity and between midnight and 05 no flights are made at all.
Whether air traffic will resume as usual on Friday morning is unclear.
