In 1927, Charles Lindbergh flew across the Atlantic Ocean alone. It took him more than 33 hours. In addition to accompanying Lindbergh on his historic flight, readers travel to the top of Mount Everest, to the bottom of the ocean, and into space to learn the stories of some of the greatest adventures of the 20th century. Historical images and full-color photographs engage readers imaginations as the main content introduces the events leading to these achievements. Detailed sidebars add information about the planning of each adventure as well as the historical context.
