Audience:On May 3, 1952 American Air Force Colonel Joseph O. Fletcher and Lieutenant Colonel William P. Benedict successfully landed an aircraft at the North Pole. Moments after the C-47 landed, Fletcher walked to the exact geographic North Pole. Navy Admiral Robert E. Peary is thought to be the first person to reach the North Pole in 1909, although this is surrounded in controversy. The submarine USS Nautilus would be the first ship to cruise under the North Pole in 1958.The geographic North Pole is the fixed point where the Earth’s axis of rotation meets its surface in the Northern Hemisphere. On a map, all lines of longitude stretch from the North Pole to the South Pole.The North Pole is about 724 kilometers (450 miles) north of the island of Greenland. It is located on a shifting ice pack in the Arctic Ocean, meaning there is no actual land beneath the 10- to 16-meter (6- to 10-foot) thick mass of ice. In the winter, this ice pack grows dramatically. At its height, it reaches the size of the continental United States. In the summer, nearly half of the ice disappears. The North Pole experiences six months of complete sunlight and six months of total darkness each year.
