Mathias Rust is a German aviator known for his flight that ended with a landing near Red Square in Moscow on 28 May 1987. A teenage amateur pilot, he flew from Helsinki, Finland, to Moscow, without authorization. According to Russian claims he was tracked several times by Soviet Air Defence Forces and civilian air traffic controllers, as well as Soviet Air Force interceptor aircraft. The Soviet fighters did not receive permission to shoot him down, and his aeroplane was mistaken for a friendly aircraft several times. Also, 28 May 1987 was Border Guards Day, leaving many guards distracted. He landed on Bolshoy Moskvoretsky Bridge, next to Red Square near the Kremlin in the capital of the USSR.

Red Square is one of the oldest and largest squares in Moscow, the capital of Russia. It is located in Moscow's historic centre, in the eastern walls of the Kremlin. It is the city's most prominent landmark, with famous buildings such as Saint Basil's Cathedral, Lenin's Mausoleum and the GUM department store. It has been a UNESCO World Heritage Site since 1990. Red Square has been the scene of executions, demonstrations, riots, parades, and speeches. Almost 73,000 square metres, it lies directly east of the Kremlin and north of the Moskva River. A moat that separated the square from the Kremlin was paved over in 1812.
