A suspected drone sighting brought disruption to Munich airport on Saturday morning, with around 26 flights reportedly diverted and further delays affecting departures. It's the latest in a growing number of drone incidents at German airports.
Figures from Germany's air navigation service, Deutsche Flugsicherung (DFS), show that 37 drone sightings were recorded in the first three months of this year alone. Yet one question often goes unanswered: who was flying them?
