Admiral Richard E. Byrd and Floyd Bennett claim to have flown over the North Pole (later discovery of Byrd's diary appears to cast some doubt on the claim.)
Richard E. Byrd
Richard Evelyn Byrd Jr. was an American naval officer, and pioneering aviator, polar explorer, and organizer of polar logistics. Aircraft flights in which he served as a navigator and expedition leader crossed the Atlantic Ocean, a segment of the Arctic Ocean, and a segment of the Antarctic Plateau. He is also known for discovering Mount Sidley, the largest dormant volcano in Antarctica.
Floyd Bennett
Floyd Bennett was a United States Naval Aviator who, along with then USN Commander Richard E. Byrd, made the first flight to the North Pole in May 1926. However, their claim to have reached the pole is disputed.
North Pole
The North Pole, also known as the Geographic North Pole or Terrestrial North Pole, is the point in the Northern Hemisphere where the Earth's axis of rotation meets its surface. It is called the True North Pole to distinguish from the Magnetic North Pole.
