The whicker seat must have given it away.....couldn't be the periscope for a windshield and 97 petcocks for the fuel system! I jest about the number of fuel cocks....think about flying the Atlantic with that dash of instruments!
Early in 1927 he obtained the backing of several St. Louis men to compete for the $25,000 prize offered by Raymond Orteig in 1919 for the first nonstop flight between New York City and Paris. In February of that year Lindbergh placed an order with Ryan Airlines in San Diego for an aircraft with specifications necessary to make the flight.
Development began based on a standard Ryan M-2, with Donald A. Hall as principal designer. Certain modifications to the basic high-wing, strut-braced monoplane design had to be made because of the nature of the flight. The wingspan was increased by 10 feet and the structural members of the fuselage and wing cellule were redesigned to accommodate the greater fuel load. Plywood was fitted along the leading edge of the wings. The fuselage design followed that of a standard M-2 except that it was lengthened 2 feet. The cockpit was moved further to the rear for safety and the engine was moved forward for balance, thus permitting the fuel tank to be installed at the center of gravity. The pilot could see forward only by means of a periscope or by turning the aircraft to look out of a side window. A Wright Whirlwind J-5C engine supplied the power.
Late in April 1927 the work on the aircraft was completed. It was painted silver and carried registration number N-X-21 1, which, with all other lettering on the plane, was painted in black. Lindbergh made several test flights, and then flew the aircraft from San Diego to New York on May 10—12, making only one stop, at St. Louis. His flight time of 21 hours, 40 minutes set a new transcontinental record.
