Panic in Denmark: Unidentified drones in airspace, Copenhagen airport shut; planes diverted

Flights at Copenhagen Airport were suspended for nearly four hours on Monday night after authorities spotted two to three large drones flying in the area.

The airport confirmed its airspace was closed around 20:30 local time (19:30 BST), halting all take-offs and landings. “No aircraft can take off or land at the airport, and as a result, several flights are being diverted to other airports,” a spokesperson said. Passengers were warned to expect ongoing delays and cancellations.

Massive flight disruption

According to Eurocontrol, at least 50 flights were cancelled, while more than 50 others were diverted to airports in Denmark and southern Sweden, including Billund, Aarhus, Malmö and Gothenburg. Flight-tracking site Flightradar24 reported that at least 35 planes bound for Copenhagen had to change course.

Minutes after the incident in Denmark, drones were also reported over parts of Norway and Sweden. Norwegian police confirmed a drone sighting near Oslo Airport, forcing air traffic onto a single runway “for safety reasons.”

Investigation under way

Danish police said they are investigating the drone activity but have not confirmed the origin of the devices. Authorities announced the airport would remain closed until 9 a.m. local time on Tuesday.
