Sikorsky S-42

The Sikorsky S-42 was a commercial flying boat designed and built by Sikorsky Aircraft to meet requirements for a long-range flying boat laid out by Pan American World Airways in 1931. The innovative design included wing flaps, variable-pitch propellers, and a tail-carrying full-length hull. The prototype first flew on 29 March 1934, and, in the period of development and test flying that followed, quickly established ten world records for payload-to-height. The "Flying Clipper" and the "Pan Am Clipper" were other names for the S-42.
During the inaugural flight of Sikorsky's previous flying boat, the S-40, on November 19, 1931, the pilot and Pan American Airways consultant, Charles Lindbergh, who considered the S-40 a monstrosity, engaged designer Igor Sikorsky in a conversation about what he thought the next airplane should look like. The conversation continued that night at the hotel in Jamaica. Sikorsky argued that design development should be incremental and that the safe approach would be a larger S-40. Lindbergh argued that a sleeker design, with a range in still air of 2,500 miles, was needed.
