Sikorsky S-40
From Wikipedia, the free encyclopedia
The Sikorsky S-40 was an amphibious flying boat built in the early 1930s, and the largest commercial airliner of its time. Flying for Pan American Airways, a total of three aircraft were built, manufactured by the Vought-Sikorsky Aircraft Division of the United Aircraft Corporation in Stratford, Connecticut. All three were scrapped during World War II. The aircraft first flew on November 19, 1931 and was piloted by Charles Lindbergh from Miami, Florida to the Panama Canal Zone. The S-40 was the first of many aircraft known as Flying Clipper and Pan Am Clipper.
The S-40 was nicknamed the "Flying Forest" for its maze of support struts.
