Is Russia testing NATO with aerial incursions in Europe? | Aviation News

Denmark was forced to close its northern Aalborg airport on Wednesday when unidentified drones were detected in its airspace. This follows Monday’s sighting of drones close to Copenhagen’s airport. Drones were later detected near several other airports on Thursday as well.

While the source of these drones has not been formally confirmed, the unmanned aerial vehicles (UAVs) which crossed into Polish and Romanian airspace earlier this month were identified as Russian.
