- The Sikorsky S-42 was an American commercial flying boat designed and built by Sikorsky to meet a 1931 requirement from Pan American for a long-range transatlantic flying boat.
Design and development
Based on the earlier Sikorsky S-40 that flew in 1931, Igor Sikorsky and Charles Lindbergh, working at the time as a Pan American Airways consultant, laid out plans for a new, larger flying boat. During the S-40's inaugural flight on 19 November 1931, the two visionaries began preliminary sketches on the back of a menu in the S-40's lounge.
Pan Am's president, Juan Trippe, had a similar vision of an aircraft able to span oceans. The new design provided for an increased lifting capacity to carry enough fuel for a 2,500 mile nonstop flight against a 30 mph (48 km/h) wind, at a cruising speed far in excess of the average operating speed of any flying boat at that time. Pan Am was also courted by Glenn Martin but Sikorsky's S-42 was delivered first, as the Martin M-130 was still almost a year away from completion.
Operational history
Flying for Pan American Airways, a total of 10 S-42s were built, manufactured by the Vought-Sikorsky Aircraft Division of the United Aircraft Corporation in Stratford, Connecticut. The aircraft first flew on 30 March 1934. The S-42 was also known as the Flying Clipper and the Pan Am Clipper.
All Sikorsky S-42s were either scrapped or destroyed in accidents.

The music is perfect. I love that trumpet sound.
My absolutely favorite airplane - of all time! - is the late 1020s two-engine bi-plane AMPHIBIAN Sikorsky S-38 (or even it's one-engine sibling, the S-39). ... It was referred to as the 'Air Yacht', and it could leisurely stay aloft at the incredibly slow stall speed in the low 60s MPH! ... I would so much have loved to leisurely fly it, island hopping, throughout the Caribbean, fish from its long flat-top nose - even barbecue on it! - while getting a tan on its lower wing! .. And, while a slow Jazzy torch song wails away from the phonograph, or the radio! .. Aaaaaaaaah! .. (There are still two or three in flying condition!)
Brave captains who met their destiny.
this is when flying was an adventure, it had style, and class! unlike today, an air bus !
what a shame...
I don't fly anymore!
Didn't they base Pan Am at Treasure Island in San Francisco back then. I still see
those big hanger there. Just wondering. Love the music of yesteryear. Thanks..
I have often wondered where the very large engines used on aircraft in World War II came from or why they were developed in the first place. Flying boats may be the source or reason for some of there development.
War das ein Konkurrenz Modell zur Boeing 314?
where was that last photo??.... Aussies??
