Munich Airport halted flights late into the night after multiple drone sightings near its runways, an abrupt interruption that resulted in more than 30 flights cancelled or diverted and, by officials’ count, nearly 3,000 passengers suddenly left with nowhere to go. In practice, those little machines complicate everything from the calculus of airspace safety to the politics of accountability. For city officials and defense planners, the lesson is structural: modern conflict and technology do not stop at frontline maps. Would you accept more checkpoints and fewer freedoms for the promise of safety, or embrace the risk that openness entails? The drones may be small, but their echo has been amplifying questions that Europe—and the world—must now answer together.
