"Navigation puzzles, controversies, historical problems, and other ponderables demystified by an expert navigator and writer. Joe Portney is a US Naval Academy graduate and Air Force navigator who has participated in three historic flights over the North Pole. He is a past President of the Institute of Navigation and recipient of the Weems Award for continuing contributions to the art and science of navigation. He has produced a wonderful little book here, chock filled with interesting tidbits, each of which can be read in a few minutes but will stimulate your thought for many days to come. Some are very basic, others more involved, but he provides a clear explanation of each. Some refer to math computations that we might not all be familiar with, but this is not a distraction from the main points being made even in these few cases."

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. It was the 1920s. The main players in this high stakes game were Richard Byrd, a dashing Navy officer and early aviation pioneer; and Roald Amundsen, a Viking in the sky, bitter rival of 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. Byrd and Amundsen’s epic struggle for air primacy ended in a Homeric episode, in which one man had to fly to the rescue of his downed nemesis, and left behind an enduring mystery: who was the first man to fly over the North Pole? Race to the Top of the World: Richard Byrd and the First Flight to the North Pole is a fast-paced, larger-than-life adventure story from Sheldon Bart, the only historian with unprecedented access to Richard Byrd’s personal archives. With powerful, never-before-seen evidence of the race to pioneer one of Earth’s last true frontiers, Race to the Top of the World is a story of a day when men were heroes and the wild was untamed.
