The Martin P5M Marlin, built by the Glenn L. Martin Company of Middle River, Maryland, was a twin piston-engined flying boat that entered service in 1951, and served into the late 1960s with the United States Navy performing naval patrols. It also served with the United States Coast Guard and the French Navy. 285 were produced.
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 Sikorsky S-29-A was a twin-engine sesquiplane airliner, first flown in 1924. It was the first aircraft that aviation pioneer Igor Sikorsky designed and built after coming to the United States, hence the special "-A" suffix signifying "America". The aircraft made many successful long-range flights, most of which Sikorsky piloted himself. The S-29-A claims a number of "firsts" in aviation, including the first twin-engine aircraft capable of maintaining altitude on one engine, the first aircraft to broadcast a radio musical program in-flight, in 1925 and in 1926 the first aircraft to display a motion picture in flight. The S-29-A was also one of the first aircraft to make use of an airstair door, located on the starboard side of the fuselage.
The Sikorsky S-40 was an American amphibious flying boat built by Sikorsky in the early 1930s for Pan American Airways.
The Sikorsky S-43 was a 1930s American twin-engine amphibious flying boat monoplane produced by Sikorsky Aircraft.
The Boeing XF6B-1 / XBFB-1 was Boeing's last biplane design for the United States Navy. Only the one prototype, Model 236, was ever built; although first flying in early 1933, it rammed into a crash barrier in 1936 and the design was not pursued further.
The Pitcairn Mailwing family was a series of American mail carrier and three-seat sport utility biplane aircraft produced from 1927 to 1931.
The Naval Air Establishment Chiang Hung was a reconnaissance seaplane developed for the Chinese Navy in the late 1920s. It was a conventional biplane design with single-bay, unstaggered wings of equal span and accommodation for the pilot and observer in tandem, open cockpits. The landing gear consisted of twin pontoons.
The Curtiss Model R was a utility aircraft produced for the United States Army and Navy during World War I. It was a conventional, two-bay biplane with slightly staggered wings of unequal span. The aircraft was provided with two open cockpits in tandem and fixed tailskid undercarriage, but many were built for the Navy with twin floats replacing the wheels. During the course of the war, Model Rs were used for general liaison and communication duties, as well for observation, training, and as air ambulances. In practice, the Curtiss powerplants supplied with these aircraft proved insufficient and were mostly replaced with Liberty engines. The Navy's Model R-3 floatplane had extended-span, three-bay wings, and was intended for use as a torpedo bomber. Some of these were later fitted with wheeled undercarriage and transferred to the Army as bombers under the designation Model R-9.
The Great Lakes BG was an American carrier-based dive bomber of the 1930s. Designed and built by the Great Lakes Aircraft Company of Cleveland, Ohio, 61 were used by the United States Navy and United States Marine Corps from 1934 to 1940.
The Martin T3M was an American torpedo bomber of the 1920s. A single-engined three-seat biplane, it became a standard torpedo bomber of the U.S. Navy, operating from both land bases and from aircraft carriers from 1926 to 1932.
The Martin T4M was an American torpedo bomber of the 1920s. A development by the Glenn L. Martin Company of their earlier Martin T3M, and, like it a single-engined biplane, the T4M served as the standard torpedo bomber aboard the aircraft carriers of the United States Navy through much of the 1930s.
The Keystone K-55 Pronto was a mail plane developed in the United States in the late 1920s.
The Thaden T-4 Argonaut was a 1930s American four-seat all-metal cabin monoplane built by the Thaden Metal Aircraft Company of San Francisco, California.
The Spartan C2 is a light aircraft produced in the United States in the early 1930s as a low-cost sport machine that would sell during the Great Depression.
The Loening SL was an American submarine-based reconnaissance flying boat designed and built by Loening Aeronautical Engineering for the United States Navy.
Naval Aircraft Factory NO was an American short-range reconnaissance/gun spotting aircraft of the 1920s. A single-engined three-seat biplane with alternative floats or wheels, six were built for the U.S. Navy.
The Sikorsky XP2S was an American biplane patrol flying boat developed for the United States Navy during the early 1930s.
G Elias & Brother was and American manufacturer of cabinets and aircraft based in Buffalo, New York in the 1920s. A.G. Elias sat on the Manufacturers Aircraft Association's board of directors along with President Frank H. Russell, VP Glenn L. Martin, Charles L. Laurence, Chance M. Vought, S.S. Bradley, George P. Tidmarsh, and Donald Douglas. E.J Elias promoted the construction of a Buffalo municipal airport to aid the local fledgling airplane industry of five aviation companies constructing airplanes and airplane parts. From 1920 to 1925, Elias company's chief engineer, David Earle Dunlap (1896-1957), designed the Elias EM-2 Expeditionary planes. He designed the NBS-3 bomber fuselage and the Elias M-1 Mail plane. Dunlap's Elias TA-1 design was the first United States Army Air Corps Trainer to have a radial engine. After tests a McCook Field, the Army Air Corps selected other manufacturers over the Elias bomber and trainer. The company designed the Elias EM-1 to meet requirements for a multirole amphibian marine expeditionary aircraft. Elias delivered six production Elias EM-2 aircraft with Liberty engines to the United States Navy in 1922.
