An 18-year-old West German pilot, Mathias Rust, evades Soviet Union air defences and lands a private plane in Red Square in Moscow, Russia.

Mathias Rust is a German aviator. In 1987, as 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.

The Union of Soviet Socialist Republics (USSR), commonly known as the Soviet Union, was a transcontinental country that spanned much of Eurasia from 1922 until it dissolved in 1991. During its existence, it was the largest country by area, extending across eleven time zones and sharing borders with twelve countries, and the third-most populous country. An overall successor to the Russian Empire, it was nominally organized as a federal union of national republics, the largest and most populous of which was the Russian SFSR. In practice, its government and economy were highly centralized. As a one-party state governed by the Communist Party of the Soviet Union (CPSU), it was the flagship communist state. Its capital and largest city was Moscow.

Red Square is one of the oldest and largest squares in Moscow, Russia. It is located in Moscow's historic centre, along 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.
