1977 Aeroflot Tupolev Tu-134 hijacking

Without bargaining power, the hijackers surrendered and were extradited back to the Soviet Union, where they were sentenced to lengthy prison terms.

[4] As the aircraft did not have the fuel to travel over the Baltic Sea to the Swedish capital, the crew were forced to divert to Helsinki Airport, Finland.

[1][2] Zagirnjak and Sheludko hoped to use them as leverage to get Finnish authorities to refuel the aircraft, replace the Soviet crew, and allow them to fly to their original destination.

[5][6] Sheludko, who had a previous criminal record for theft, would eventually be sentenced to fifteen years; Zagirnjak received eight.

The Washington Post reported that it was the third such crime in a week, with the others occurring in the Middle East and South America, and that the last successful hijacking of a Soviet aircraft had been only two months earlier.
