A video grab shows Russia's Prime Minister Vladimir Putin looking through the porthole of the "Mir-2" mini-submersible at Lake Baikal, August 1, 2009. Putin dived into the depths of the lake aboard the mini-submersible on Saturday in a stunt that adds a new dimension to his carefully cultivated macho image. The judo black belt -- who has already conquered the skies in a fighter aircraft and shot a Siberian tiger in the wild -- will descend 1,400 metres (4,600 ft) below the surface of the world's deepest lake to inspect valuable gas crystals.
