WhereOver Dubrovnik-Ćilipi and Prevlaka, Yugoslavia (now Croatia/Montenegro)

In February 1975 Yugoslav air-defence radars picked up an object that came in from the Adriatic each day and stopped over Dubrovnik's airport. MiG-21s were scrambled about fifteen times and got radar locks, but their missiles would not respond. A general turned the Prevlaka headland into a war room and Tito was briefed daily. A colonel who guided the pilots told the story in 2018.
