In the age of adventure, when dirigibles coasted through the air and vast swaths of the Earth remained untouched and unseen by man, one pack of relentless explorers competed in the race of a lifetime: to be the first aviator to fly over the North Pole. What inspired their dangerous fascination? For some, it was the romantic theory about a “lost world,” a hidden continent in the Arctic Ocean. Others were seduced by new aviation technology, which they strove to push to its ultimate limit. The story of their quest is breathtaking and inspiring; the heroes are still a matter of debate. In this episode I talk with Sheldon Bart, author of “Race to the Top of the World: Richard Byrd and the First Flight to the North Pole.” about Richard Byrd, a Navy officer and early aviation pioneer; and Roald Amundsen, Byrd’s and a hardened veteran of polar expeditions. Each man was determined to be the first aviator to fly over the North Pole, despite brutal weather conditions, financial disasters, world wars, and their own personal demons.
