A short introduction: At the beginning of 1947 the American explorer Richard Byrd leads yet another expedition to Antarctica, but this time it's different. The expedition is financed entirely by the US Navy (Operation High Jump) and consists of an aircraft carrier, 12 surface ships, one submarine, more than 20 airplanes and helicopters and about 5000 men, "a strange team for a scientific expedition". The expedition concentrates on Queen Maud's Land, which is a big part of the Antarctic mainland. The expedition is meant to last for 6 months, but is aborted after only 2 months. They lost a destroyer, almost half their carrier based aircraft, and dozens of sailors and officers. What had happened?
