On 10 July 1977, two Soviet hijackers took over an Aeroflot Tupolev Tu-134 flight in the hope of diverting it to Stockholm, Sweden. Lacking the fuel to do this, the aircraft landed at Helsinki Airport, Finland, where the hijackers kept hostages to demand that the Finnish authorities refuel the aircraft and provide it with a new crew. However, the hostages escaped after the hijackers fell asleep. Without bargaining power, the hijackers surrendered and were extradited back to the Soviet Union, where they were sentenced to lengthy prison terms.
