MOSCOW, August 22 (RIA Novosti) – A Russian Zubr (“Bison”) hovercraft, the largest type of military hovercraft in the world, on Sunday ploughed into a Kaliningrad Region beach filled with dozens of sunbathers, the Komsomolskaya Pravda newspaper reported.

The daily quoted the Russian Defense Ministry’s press service as saying the landing was part of a routine exercise on ministry property and “what people were doing at the beach on the territory of a military base is unclear.”

Zubr-class hovercraft can simultaneously carry several tanks and up to 500 troops. The landing, during which marines reportedly ran out and cordoned off the vehicle, occurred in the town of Mechnikovo, in Russia’s western-most region.
