flying boat s built to compete in the transatlantic air travel trade carrying 40 or more passengers across theAtlantic Ocean . Only 3 were produced: "Excalibur", "Excambian" and "Exeter".Sharpe, 2000. p 309.]Development
In the early days of commercial air travel, large four-engine flying boats built by companies like
Consolidated Aircraft ,Boeing , Shorts,Breguet ,Latecoere andDornier soon established the legitimacy of air travel. At first, long flights meant small payloads, giving passengers a sense of airborne freedom as they walked from smoking lounge to dining room, to sleeping compartment on these flights. Freedom of movement and more of the ultimate luxury, speed.One of the leaders in flying boat design and production was Russian immigrant
Igor Sikorsky who had founded Sikorsky Aero Engineering Company when he came to the US in 1919. In 1930 his company became a subsidiary ofUnited Aircraft . Sikorsky manufactured flying boats, such as the S-42 used byPan Am for trans-Atlantic flights and known as Pan Am Clippers. Looking at the longer routes across the Pacific, Pan Am needed planes with longer range than was available with the S-42.Juan Trippe , Pan Am's president, didn't like the updated S-42 design proposed by Sikorsky, instead going with theMartin M-130 and later theBoeing 314 Clipper .

By 1940, Sikorsky, now merged with
Chance Vought under the umbrella ofUnited Aircraft , produced the VS-44. A single deck seaplane with two-rowPratt & Whitney Twin Wasp s rated at 1,200 horsepower (900 kW) each, the new aircraft was 80 feet (24 m) in length and weighed in at 57,500 lb (26,000 kg) for takeoff. TheBoeing 314 Clipper was larger and boasted more powerfulWright Twin Cyclone s of 1,600 hp (1193 kW), but the VS-44 was 30 mph (48 km) faster and could fly an average payload more than 4,000 miles (6,400 km), out distancing the big Boeing by 500 miles (800 km) and earning bragging rights with the longest full-payload range of any aircraft in the world. The VS-44 brought home several new world records after it went into operation, but the limited production would never even recoup the VS-44’s development costs.American Export Airlines (AEA) ordered for three VS-44s, dubbed ‘Flying Aces’ and named "Excalibur" (NX41880; later as NC41880), "Excambian" (no NX; later as NC41881) and "Exeter" (no NX; later as NC41882) after the parent company'sFour Aces . AEA had grown out of theAmerican Export Lines steamship line, so naturally these planes gave nothing away to cruise ships. Sikorsky’s standard of luxury boasted full-length beds, dressing rooms, full galley, snack bar, lounge and fully controlled ventilation.Operational service
World War II
World War II had begun, though, putting civilian transatlantic air service on hold. Now under a Navy contract and with the Navy designation JR2S-1, AEA’s three VS-44’s continued flying betweenNew York, New York andFoynes ,Ireland , carrying passengers, freight and war materiel. The first VS-44, "Excalibur", crashed on takeoff in 1942 atBotwood ,Newfoundland , killing 11 of the 37 aboard.

Now, a U.S. team aims to recover its human remains,"] "globeandmail.com", Sept. 11, 2008.]Post War Service
After the war, the big Sikorsky ‘boats continued to fly for the airline, which had renamed itself
American Overseas Airlines (AOA) and was operated byAmerican Airlines . AOA sold Excambian in 1949 to Tampico Airlines.In 1946 "Exeter" was sold to TACI of
Montevideo ,Uruguay , as CX-AIR. It crashed Aug 15, 1947 while landing in River Plate off Montevideo when (allegedly) returning from a smuggling flight to Paraguayan rebels. 4 out of the 5 crew were killed, but both passengers survived.A short-lived effort to restore the only remaining VS-44 to run freight in the Amazon came to naught, leaving the former AOA ‘boat stranded in Ancon Harbor,
Peru .By the late 1950s, two Southern
California businessmen had heard of the "Excambian"'s plight and had her ferried to Long Beach, where restoration work began. Dick Probert and Walter von Kleinsmid of Avalon Air Transport, (AAT) thought the big VS-44 would be perfect for the Catalina tourist trade. AAT named her "Mother Goose", to complement the line’sGrumman Goose amphibians, and plans were made to utilize her to meet summer travel demands. In the winter, N41881 would undergo maintenance."Excambian" carried thousands of passengers for AAT until 1967 when it was sold to Charles Blair of Antilles Air Boats. Blair, husband of actress
Maureen O'Hara , acquired the "Excambian" to ferry passengers among the Virgin Islands. In January 3, 1969 she was extensively damaged by rocks whiletaxiing atCharlotte Amalie , US Virgin Islands. It was judged beyond economic repair and beached in March 1972 and converted to a hot dog stand.Restoration and Museum Piece
In 1976, "Excambian" was donated to the
Naval Aviation Museum atPensacola, Florida and eventually put on permanent loan to theNew England Air Museum inConnecticut . NEAM restored "Excambian" to its WWII livery with volunteer help from some of the former Sikorsky workers who had built the original VS-44.
