The Sikorsky S-43 (sometimes referred to as the Baby Clipper) is a 1930s American twin-engine amphibious flying boat monoplane produced by Sikorsky Aircraft.
The S-43 first flew in 1935, and was a smaller version of the Sikorsky S-42 "Clipper". It accommodated between 18 and 25 passengers, with a separate forward cockpit for the two crew. [1] The S-43 was known as the "Baby Clipper" in airline service.
On April 14, 1936, an S-43 with a 500 kg (1,100 lb) payload, piloted by Boris Sergievsky, set an altitude record for amphibious aircraft when it reached an altitude of 27,950 ft (8,520 m) over Stamford, Connecticut, with designer Igor Sikorsky aboard. [2]
Approximately 53 S-43s were built, including examples of the twin-tailed S-43B. [1]
The S-43 was used primarily by Pan American World Airways for flights to Cuba and within Latin America. Inter-Island Airways of Hawaii (Inter-Island changed its name to Hawaiian Airlines in 1941) was the launch customer for the S-43. [3] Inter-Island operated four S-43's to ferry Pan Am Clipper passengers and local residents from Honolulu throughout the Hawaiian Islands. Inter-Island sold its only twin-tail version to KLM. [3] One aircraft was purchased by Norwegian airline Det Norske Luftfartselskap. Panair do Brasil operated seven aircraft. Five S-43s were used between 1937 and 1945 by the French company Aéromaritime on a colonial airway between Dakar (Senegal) and Pointe-Noire (Congo). [4] Reeve Aleutian Airways owned two S-43s during the 1950s, one operational (N53294 purchased 1948 and trade for G-21 in 1957) and one for spares (fuselage at Alaska Aviation Heritage Museum). Another S-43 was operated in Alaska with an unknown operator, wrecked at Chignik, AK, 1950s. [5]
The U.S. Army Air Corps acquired five aircraft in 1937 under the designation OA-8 for transport of freight and passengers. [6] The U.S. Navy purchased 17 aircraft between 1937 and 1939 as the JRS-1, two of which served with the U.S. Marine Corps. One JRS survived by the end of 1941. [7]
The Chilean Air Force (FACH) (formerly known as Fuerza Aérea Nacional (FAN)) in 1936 bought 2 S-43: No. 1 named "Magallanes" and the No.2 named "Chiloé", because that aircraft was going to use in the Línea Aérea Experimental Puerto Montt-Magallanes (Experimental Air Line from Puerto Montt to Magallanes) flying through the Patagonian fjords. [8]
Two aircraft went to private owners: William Kissam Vanderbilt II and Howard Hughes.
Hughes' S-43 N440 was the last example to fly. [9] It is now owned by Kermit Weeks and was at the Fantasy of Flight Museum restoration facility, in Polk City, Florida awaiting reassembly and restoration.
The Smithsonian National Air & Space Museum's Steven F. Udvar-Hazy Center in Virginia has now put a Sikorsky JRS-1 on display. This aircraft was on duty at Pearl Harbor on December 7th, 1941. [10]

The Boeing 377 Stratocruiser was a large long-range airliner developed from the C-97 Stratofreighter military transport, itself a derivative of the B-29 Superfortress. The Stratocruiser's first flight was on July 8, 1947. Its design was advanced for its day; its relatively innovative features included two passenger decks and a pressurized cabin. It could carry up to 100 passengers on the main deck plus 14 in the lower deck lounge; typical seating was for 63 or 84 passengers or 28 berthed and five seated passengers.
The Douglas DC-7 is an American transport aircraft built by the Douglas Aircraft Company from 1953 to 1958. A derivative of the DC-6, it was the last major piston engine-powered transport made by Douglas, being developed shortly after the earliest jet airliner—the de Havilland Comet—entered service and only a few years before the jet-powered Douglas DC-8 first flew in 1958. Unlike other aircraft in Douglas's line of propeller-driven aircraft, no examples remain in service in the present day, as compared to the far more successful DC-3 and DC-6.

The Harbin Y-12 is a high wing twin-engine turboprop utility aircraft built by Harbin Aircraft Industry Group (HAIG).
Samoan Clipper was one of ten Pan American Airways Sikorsky S-42 flying boats. It exploded near Pago Pago, American Samoa, on January 11, 1938, while piloted by aviator Ed Musick. Musick and his crew of six died in the crash. The aircraft was carrying only airmail and express freight; no passengers were aboard.
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.
The Sikorsky S-38 was an American twin-engined ten-seat sesquiplane amphibious aircraft. It was Sikorsky's first widely produced amphibious flying boat, serving successfully for Pan American Airways and the United States military.
The Lockheed Model 14 Super Electra was an American civil passenger and cargo aircraft built by the Lockheed Aircraft Corporation during the late 1930s. An outgrowth of the earlier Model 10 Electra, the Model 14 was also developed into larger, more capable civil and military versions.
The Sikorsky S-40 was an American amphibious flying boat built by Sikorsky in the early 1930s for Pan American Airways. During WW2 they were used by the United States Navy for training.
The Martin 156, referred to in the press variously as the "Russian Clipper", "Moscow Clipper", or "Soviet Clipper" was a very large flying boat aircraft intended for trans-Pacific service. The single example of the M-156 was designed and built in response to a request from Pan American World Airways to provide a longer-range replacement for the Martin M-130.
The Short Solent is a passenger flying boat that was produced by Short Brothers in the late 1940s. It was developed from the Short Seaford, itself a development of the Short Sunderland military flying boat design.

Based on the XPBS-1 patrol bomber, the VS-44 was designed primarily for the transatlantic passenger market, with a capacity of 40+ passengers. Three units were produced: Excalibur, Excambian, and Exeter, plus two XPBS-1 prototypes.
The Consolidated Commodore was an American flying boat built by Consolidated Aircraft and used for passenger travel in the 1930s, mostly in the Caribbean, operated by companies like Pan American Airways.

Three were built: the China Clipper, the Philippine Clipper and the Hawaii Clipper. All three had crashed by 1945. A similar flying boat design called the Martin 156) and named Russian Clipper, was built for the Soviet Union; it had a larger wing and twin vertical stabilizers.

The Douglas DC-2 is a 14-passenger, twin-engined airliner that was produced by the American company Douglas Aircraft Company starting in 1934. It competed with the Boeing 247. In 1935, Douglas produced a larger version called the DC-3, which became one of the most successful aircraft in history.
The Seaplane Baby Clipper NC 16933 Crash took place in Rio de Janeiro on August 13, 1939.
