(Reuters) -Denmark's Aalborg airport, used for commercial and military flights, was closed due to drones in its airspace, police said early on Thursday, two days after Copenhagen airport was shut over drone sightings that raised European security concerns.
A string of drone sightings and digital outages has repeatedly disrupted airports since 2017. These episodes bypass core flight‑safety systems and instead hit choke points such as check‑in and boarding systems, power infrastructure and airfield perimeters, causing ripple effects across networks.
