Munich airport’s temporary closure on Thursday night after multiple drone sightings has highlighted not only the fragility of European aviation but also pressing shortcomings in insurance cover for emerging risks.
Air traffic control halted departures and arrivals after drones were spotted overhead, forcing the cancellation of 17 flights and the diversion of 15 more. Almost 3,000 passengers were stranded in terminals as staff distributed blankets and camp beds. Flights resumed at dawn, but the disruption has become a case study in how small, hard-to-trace devices can inflict large-scale losses.
Charles Röbin, partner at Clyde & Co, told Insurance Business UK, “The recent drone disruption at Munich Airport highlights a growing risk for the aviation sector.”
He underscored the attribution challenge and its knock-on effects for policy response, “These incidents expose gaps in liability attribution and raise questions around business interruption coverage, which often requires physical damage to trigger a claim," he said.
With similar incursions already forcing temporary shutdowns in Denmark and Norway, Röbin urges insureds to review wordings in light of non-damage losses: “With drone threats becoming increasingly common, it is important that insureds reassess how their insurance policies respond to non-physical disruptions and consider broader coverage for emerging risks.”
While legislators debate shoot-down powers and counter-drone systems, the insurance task is immediate: aligning coverage triggers and exclusions with disruption that leaves no physical trace yet generates material financial loss.
In late 2025, a spate of drone sightings near airports and military installations across Europe have triggered flight suspensions, airport closures, and diplomatic alarm. While each event is short in duration, the pattern has raised serious questions about vulnerabilities in aviation security, the readiness of counter-drone systems, and the potential for hybrid or asymmetric tactics to target civilian infrastructure.

Key Effects & Notes |
| September 22, 2025 |
Copenhagen Airport, Denmark |
Two to three large drones sighted within controlled airspace. Flights halted for nearly 4 hours. |
Around 31 flights diverted; ~100 delayed or cancelled; about 20,000 passengers affected. Authorities described the drone operator as “capable.” |

September 22, 2025 (same night) |
Oslo Airport, Norway |
Drone sighting forced a three-hour closure. |
Several flights cancelled or diverted. Two unidentified drones reported. |
| September 24–25, 2025 |
Aalborg Airport, Denmark, plus Esbjerg, Sønderborg, Skrydstrup |
Multiple drone incursions led to temporary closures and “zero-rate” restrictions on traffic. |
Incidents extended over two nights, with operations repeatedly disrupted. |
| September 25, 2025 |
Billund and Kastrup, Denmark |
More drone sightings triggered further airspace restrictions, including over military facilities. |
Danish officials warned of a possible “hybrid attack.” |
|
September 27, 2025 |
Karup Air Base and other Danish military bases |
Multiple drones detected near strategic infrastructure. |
NATO stepped up surveillance; Denmark deployed additional defence assets. |
|
October 3, 2025 |
Munich Airport, Germany |
Drone sightings forced an overnight suspension of operations. |
Seventeen flights cancelled, 15 diverted, nearly 3,000 passengers affected. Operations resumed the following morning. |
Historical context: Similar large-scale disruptions have precedent. The most infamous occurred at London Gatwick in 2018, when 33 hours of drone sightings led to 1,000 flight cancellations or diversions and affected 140,000 passengers.
