The Organization for Security and Cooperation in Europe’s (OSCE) Special Monitoring Mission (SMM) in Ukraine reported at the end of October that one of its long-range unmanned aerial vehicles (UAV) had gone missing. According to an OSCE spot report (Osce.org, October 27), the drone disappeared while flying above a non-government-controlled area in Donetsk region. The UAV in question apparently experienced signal interference – which the OSCE SMM assessed to be jamming – while operating at an altitude of about 7,000 feet.
