MS Estonia was a cruiseferry built in 1980 at the West German shipyard Meyer Werft in Papenburg. In 1993, she was sold to Nordström & Thulin for use on Estline's Tallinn–Stockholm route. The ship's sinking on 28 September 1994, in the Baltic Sea between Sweden, Finland and Estonia, was one of the worst maritime disasters of the 20th century, claiming 852 lives.

The official report concluded that the bow door had separated from the vessel, pulling the ramp ajar. The ship was already listing because of poor cargo distribution, and the list increased rapidly, flooding the decks and the cabins. Shortly, power failed altogether, inhibiting search and rescue, and a full-scale emergency was not declared for 90 minutes. Of the 989 on board, 138 were rescued. The report criticised the passive attitude of the crew, failing to notice that water was entering the vehicle deck, delaying the alarm, and providing minimal guidance from the bridge.
