Because Rust's flight seemed like a blow to the authority of the Soviet regime, it was the source of numerous jokes and urban legends. For a while after the incident, Red Square was jokingly referred to by Muscovites as Sheremetyevo-3 (Sheremetyevo-1 and -2 being the two terminals at Moscow's main international airport).[19] At the end of 1987, the police radio code used by law enforcement officers in Moscow was allegedly updated to include a code for an aircraft landing.[20]
