Charles Augustus Lindbergh was an American aviator, military officer, author, inventor, and activist. On May 20–21, 1927, Lindbergh made the first nonstop flight from New York City to Paris, a distance of 3,600 miles (5,800 km), flying alone for 33.5 hours. His aircraft, the Spirit of St. Louis, was designed and built by the Ryan Airline Company specifically to compete for the Orteig Prize for the first flight between the two cities. Although not the first transatlantic flight, it was the first solo transatlantic flight, the first nonstop transatlantic flight between two major city hubs, and the longest by over 1,900 miles (3,000 km). It is known as one of the most consequential flights in history and ushered in a new era of air transportation between parts of the globe.
