Sightings come shortly after disagreements over ‘drone wall’ project at the EU leaders’ meeting in Copenhagen

Munich has joined a growing list of European airport disrupted by drone sightings in recent weeks, with 17 flights cancelled, 15 diverted elsewhere, and thousands of passengers facing disruption to their travel overnight.

Several people reported seeing drones near the airport, with a further sighting later confirmed within the restricted zone, forcing air traffic control to suspend operations pending investigation.
