Drones that shut Denmark’s main airport appeared to have been flown by “a capable operator” seeking to demonstrate certain abilities, police say.
The airports in Copenhagen and Oslo, the two busiest in the Nordic region, were shut for hours after drones were observed in their airspace late on Monday, leaving tens of thousands of passengers stranded as flights were diverted.
“We have concluded that this was what we would call a capable operator,” Danish police Chief Superintendent Jens Jespersen told reporters on Tuesday, referring to the drones observed in Copenhagen.
“It's an actor who has the capabilities, the will and the tools to show off in this way,” Mr Jespersen said, adding that it was too early to say if the incidents in Denmark and Norway were linked.
Copenhagen Airport was closed for four hours when two or three large drones were seen flying in its immediate vicinity, officials said, while the Oslo Airport was closed for three hours following two sightings, according to local police.
Mr Jespersen said the drones in Denmark came from several different directions, turning their lights on and off, before eventually disappearing after several hours.
Copenhagen diverted 31 flights to other airports, causing ripple effects that delayed or cancelled around 100 flights and affected some 20,000 passengers, a spokesperson told reporters on Tuesday.
The airport shutdowns came after a string of disruptions at European airports in recent days.
A cyber attack last Friday knocked out check-in and boarding systems supplied by Collins Aerospace, a unit of RTX, affecting operations at London's Heathrow and the Berlin and Brussels airports over the weekend and into Monday.
