Copenhagen, the busiest airport in the region, halted flights for nearly four hours after multiple large drones were spottedCopenhagen: Copenhagen and Oslo airports were forced to shut down for several hours on Monday evening due to multiple drone sightings, causing major travel disruptions across Scandinavia. Danish authorities closed Copenhagen Airport—the busiest in the Nordic region—after two to three large drones were observed flying near the airfield, suspending all take-offs and landings for nearly four hours. Oslo Airport similarly closed its airspace for about three hours after a drone sighting, rerouting flights to other airports. Danish police described the drones as operated by a "skilled individual" intending to showcase specific capabilities, but no suspects have yet been identified. Copenhagen and Oslo airports reopened early Tuesday, but travellers are warned to expect ongoing delays as security operations tighten and investigations proceed.
