The likely continuation of Russia-linked drone and sabotage incidents impacting European aviation over the next 12 months will impose higher security and operating costs, reduce capacity and add greater logistical complexity, while a single high-impact incident could trigger a far more consequential geopolitical and economic response. In recent months, European aviation has been facing a growing number of security incidents associated with the Russia-Ukraine conflict, including suspicious drone incursions and attempted sabotage around airports and other critical infrastructure. The most significant recent case occurred in August at Leipzig/Halle Airport in Germany , where a drone carrying explosives was discovered near a Ukrainian Antonov cargo aircraft; the airport was temporarily closed and the device was defused. On Sept. 1, the German government publicly alleged that Russia was responsible for the attempted attack, something Moscow denied.
