Drone alarm at Copenhagen airport: chaos in air traffic!
On Monday evening, September 23, 2025, Copenhagen Airport experienced a four -hour state of emergency due to the viewing of several drones above the airport area. Air traffic was discontinued from 8:26 p.m. local time, and it was neither possible to start aircraft nor to land. This drastic measure meant that numerous flights were deleted or delayed and dozens of machines were redirected to other airports such as Malmö, Billund, Aarhus and Gothenburg. Only one plane could land around 9:30 p.m. because it could no longer be kept in the air due to the lack of fuel.
The police immediately responded to the sightings with a large contingent and initiated investigations into the drones. Between two and four large drones have been viewed above the airport area, but so far there is no information about the origin or for the purpose of these drones. The airport press spokeswoman expressed the urgent interest in a quick clarification of the situation in order to resume normal operation. The complete air traffic remained until after midnight, with the first flight after the SK7744 was reopened at 0:37 a.m.
Effects on air traffic
The sighting of drones had a massive impact on air traffic at Copenhagen airport. Over 35 flights were redirected due to the drone sightings. The police stated that it was still unclear when the operation can be ended. According to information from [Merkur] (https://www.merkur.de/welt/Flimhafen-kopenhagen-blahnen-alarm-alarm-alarm-air traffic-Status-Ststopp, no confirmed connections to previous incidents in Europe were established, which may have been associated with Russia. This uncertainty ensures additional tensions among the passengers.
The incident shows a growing problem that also affects other European airports. This is reported [Fraport] (https://www.fraport.com/de/newsroom/service-news/2025/strikte-massungen- against-dronepsungungs-am-flughafen-frankfur.html) that drone flights can be serious threats and cause economic damage. Airport operators and security authorities are working intensively to identify drones at an early stage and to take suitable measures for defense.
This year, police authorities have already arrested several drone pilots and initiated procedures. Drone sightings in security areas, such as at Frankfurt Airport, should be reported to the security emergency call from Fraport AG or the police immediately. The incident in Copenhagen underlines the need for strict surveillance and security measures to ensure security in air traffic.
Passengers at Copenhagen Airport were asked to find out about possible flight cancellations at their airlines and to consider the current situation.
