The ''Spirit of St. Louis'' (Registration: N-X-211) is the custom-built, single engine, single-seat monoplane that was flown solo by Charles Lindbergh on May 20–21, 1927, on the first non-stop flight from New York to Paris for which Lindbergh won the $25,000 Orteig Prize.〔("National Air and Space Museum, Milestones of Flight Exhibits: Spirit of St. Louis." ) ''Nasm.si.edu'', May 21, 2007. Retrieved: July 29, 2009.〕 Lindbergh took off in the ''Spirit'' from Roosevelt Airfield, Garden City (Long Island), New York and landed 33 hours, 30 minutes later at Aéroport Le Bourget in Paris, France, a distance of approximately 3,600 miles (5,800 km).〔Jackson 2012, pp. 512–516.〕 One of the best known aircraft in the world, the ''Spirit'' was built by Ryan Airlines in San Diego, California, which at the time was owned and operated by Benjamin Franklin Mahoney who had purchased it from its founder, T. Claude Ryan, in 1926. The ''Spirit'' is now on permanent display in the main entryway's ''Milestones of Flight'' gallery at the Smithsonian's National Air and Space Museum in Washington D.C. ==Design and development== Officially known as the Ryan NYP (for New York to Paris), the single engine monoplane was designed by Donald A. Hall of Ryan Airlines and was named ''The Spirit of St. Louis'' in honor of Lindbergh's supporters from The St. Louis Raquette Club in his then hometown of St. Louis, Missouri. To save design time, the NYP was loosely based on the company's 1926 Ryan M-2 mailplane with the main difference being the 4,000 mile range of the NYP, and as a non-standard design the Government assigned it the registration number N-X-211 (for "experimental"). Hall documented his design in "Engineering Data on the ''Spirit of St. Louis''" which he prepared for the National Advisory Committee for Aeronautics (NACA) and is included as an appendix to Lindbergh's 1953 Pulitzer Prize winning book, ''The Spirit of St. Louis.'' B.F. "Frank" Mahoney and Claude Ryan had co-founded the company as an airline in 1925 and the latter remained with the company after Mahoney bought out his interest in 1926 although there is some dispute as to how involved Ryan may have been in its management after selling his share. It is known, however, that Hawley Bowlus was the factory manager who oversaw construction of the Ryan NYP, and that Mahoney was the sole owner at the time of Donald A. Hall's hiring. Although the ''Spirit'' was designed and built in San Diego for a flight from New York to Paris, it was named after the city of St. Louis, Missouri because both Lindbergh and his financial backers lived in that city. The ''Spirit'' was designed and built to compete for the $25,000 Orteig Prize for the first non-stop flight between New York and Paris which Lindbergh would win in the single engine monoplane.〔Belfiore 2007, pp. 15–17.〕 Hall and Ryan Airlines staff worked closely with Lindbergh to design and build the ''Spirit'' in just 60 days. Although what was actually paid to Ryan Airlines for the project isn't clear, Mahoney offered to do it at cost. After first approaching several major aircraft manufacturers without success, in early February 1927, Lindbergh, who as a U.S. Air Mail pilot familiar with the good record of the M-1 with Pacific Air Transport, wired, "Can you construct Whirlwind engine plane capable flying nonstop between New York and Paris ...?" Mahoney was away from the factory, but Claude Ryan answered, "Can build plane similar M-1 but larger wings... delivery about three months." Lindbergh wired back that due to competition, delivery in less than three months was essential. Many years later, Jon van der Linde, chief mechanic of Ryan Airlines, recalled, "But nothing fazed B.F. Mahoney, the young sportsman who had just bought Ryan." Mahoney boldly telegraphed Lindbergh back the same day: "Can complete in two months." Lindbergh arrived in San Diego on February 23 and toured the factory with Mahoney meeting factory manager Hawley Bowlus, chief engineer Donald Hall, and sales manager A.J. Edwards. After further discussions between Mahoney, Hall and Lindbergh, Mahoney offered to build the ''Spirit'' for $10,580, restating his commitment to deliver it in 60 days. Lindbergh was convinced: "I believe in Hall's ability; I like Mahoney's enthusiasm. I have confidence in the character of the workmen I've met." He then went to the airfield to familiarize himself with a Ryan aircraft, either an M-1 or an M-2, then telegraphed his St. Louis backers and recommended the deal, which was quickly approved. Mahoney lived up to his commitment. Working exclusively on the aircraft and closely with Lindbergh, the staff completed the ''Spirit of St. Louis'' 60 days after Lindbergh arrived in San Diego. Powered by a Wright Whirlwind J-5C 223-hp radial engine, it had a 46-foot wingspan, 10 feet longer than the M-1, to accommodate the heavy load of 425 gallons of fuel. In his 1927 book ''We'', Lindbergh acknowledged the achievement of the builders with a photograph captioned "The Men Who Made The Plane," identifying: "B. Franklin Mahoney, President, Ryan Airlines," Bowlus, Hall and Edwards standing with the aviator in front of the completed aircraft.〔Tekulsky, Joseph D. ("B.F. Mahoney." ) ''charleslindbergh.com.''
