After WWII Admiral Byrd led Operation Highjump to Antarctica. This was a huge expedition of 4,700 men, 13 ships (including an aircraft carrier), 19 airplanes, and a large contingent of scientists. Vast stretches of unexplored land from the Antarctic Peninsula to the Ross Ice Shelf to Wilkes Land south of Australia were mapped and the expedition returned with a large quantity of meteorological and scientific data.
