Overview

• Aalborg Airport closed for several hours on September 25 after multiple drones were observed with lights, and police later reported sightings near Esbjerg, Sønderborg and the Skrydstrup fighter airbase.
• Copenhagen and Oslo temporarily halted operations on September 22 following reports of two to three drones near each airport before flights later resumed.
• Danish police say the aircraft displayed a similar pattern to earlier incidents and appeared to be flown by an experienced operator.
• Attempts to shoot down the drones were unsuccessful, and no suspects have been detained as investigations continue.
• Norway says it has not established a link between the Oslo and Copenhagen cases or tied them to any country, while Denmark characterizes the Copenhagen episode as a serious attack on critical infrastructure and has the armed forces assisting police.
