Charles Augustus Lindbergh was an American aviator and military officer. On May 20–21, 1927, he 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 and the longest at the time by nearly 2,000 miles (3,200 km). It became known as one of the most consequential flights in history and ushered in a new era of air transportation between parts of the globe.

The Spirit of St. Louis is the custom-built, single-engine, single-seat, high-wing monoplane that was flown by Charles Lindbergh on May 20–21, 1927, on the first solo nonstop transatlantic flight from Long Island, New York, to Paris, France, for which Lindbergh won the $25,000 Orteig Prize.
