1968- . German aviator who in May 1987 piloted a light plane from Finland to Moscow, landing in Red Square. Found guilty of `malicious hooliganism', he was imprisoned until 1988. His exploit, carefully timed to take place on the USSR's `national border guards' day', highlighted serious deficiencies in the Soviet air-defence system and led to the dismissal of the defence minister. Rust, despite pleading that his actions had been designed to promote world peace, was sentenced to four years' imprisonment by the Soviet authorities. After serving 14 months in a KGB prison in Lefortovo, he was released and sent home as a humanitarian gesture by the Gorbachev administration.
