Overview
- The Deutsches Zentrum für Luft- und Raumfahrt found 226 reported drone incidents in the past year, of which 116 led to full or partial closures at 25 airports and caused direct costs of about €60 million that rise to as much as €160 million when follow-on effects are included.
- About 70 percent of flight diversions linked to drone sightings trace back to the large connecting hubs of Munich and Frankfurt, which experienced multi-day restrictions in October 2025 and a major disruption in July 2025 respectively.
- Most sightings are recorded by pilots and tower controllers or flagged by Bundespolizei detection systems, but officials usually cannot identify who operated the drones, complicating enforcement and prosecution.
- Airlines and airports bear layered costs from disruptions, including extra fuel from reroutes, longer flight times, passenger care and replacement flights, and lost airport fee revenue from cancellations.
- Authorities face legal and technical limits: drone flights are banned within 1.5 kilometres of airports and can carry prison terms up to ten years, yet large-scale neutralization and reliable attribution remain operationally difficult and are the focus of DLR countermeasure research.
