White Christmas assured. Painted orange, this Mi-4 took part in the First Soviet Antarctic Expedition which established the Soviet Mirny polar station in 1956. Very soon after a visting US Navy photographer took this shot, the helicopter was struck off charge and dumped nearby as returning it to Russia for a necessary overhaul was deemed uneconomical.
