  "description": "On the evening and night of September 22, 2025, unknown objects flying at speeds over 100 km/h were detected by radar over Øresund heading towards Saltholm near Copenhagen Airport, which was closed following drone observations. The police investigation included extensive witness interviews and analysis of large radar datasets from Copenhagen Airport's bird radar and Naviair's Danish airspace radars. Naviair's data contained unexplained radar tracks moving at high speed possibly indicating drone activity. However, these objects' speeds exceed typical commercial drone capabilities, and no conclusive evidence was found to prove drone presence or assign criminal liability. Nine months after the airport closure, Copenhagen Police decided to discontinue the investigation as the evidence was insufficient for prosecution. The decision followed a report from the Technical University of Denmark (DTU) dated June 11, 2026, which found no substantiating data for continuing the case. The airport has since strengthened its technical drone detection capabilities. The incident occurred days before an EU summit in Copenhagen and against a backdrop of cyberattacks on European airports and airspace violations in Poland. The Defense Intelligence Service reported separate confirmed drone sightings over Danish military sites and vessels around the same time. From September 22 and onwards, over 7,000 drone sighting reports were received nationwide, many eventually attributed to commercial flights, wind turbines, or stars.",
