The Glenn L. Martin Company—also known as The Martin Company from 1957-1961—was an American aircraft and aerospace manufacturing company founded by aviation pioneer Glenn L. Martin, and operated 1917–1961. The Martin Company produced many important aircraft for the defense of the US and allies, especially during World War II and the Cold War. During the 1950s and 60s, the Martin Company moved from the aircraft industry into the guided missile, space exploration, and space utilization industries.
The Hughes H-4 Hercules is a prototype strategic airlift flying boat designed and built by the Hughes Aircraft Company. Intended as a transatlantic flight transport for use during World War II, it was not completed in time to be used in the war. The aircraft made only one brief flight, on November 2, 1947, and the project never advanced beyond the single example produced.
A flying boat is a fixed-winged seaplane with a hull, allowing it to land on water, that usually has no type of landing gear to allow operation on land. It differs from a floatplane as it uses a purpose-designed fuselage which can float, granting the aircraft buoyancy. Flying boats may be stabilized by under-wing floats or by wing-like projections from the fuselage.
A seaplane is a powered fixed-wing aircraft capable of taking off and landing (alighting) on water. Seaplanes are usually divided into two categories based on their technological characteristics: floatplanes and flying boats; the latter are generally far larger and can carry far more. Seaplanes that can also take off and land on airfields are in a subclass called amphibious aircraft, or amphibians. Seaplanes were sometimes called hydroplanes, but currently this term applies instead to motor-powered watercraft that use the technique of hydrodynamic lift to skim the surface of water when running at speed.
The Blohm & Voss BV 238 was a German flying boat built during World War II. It was the heaviest aircraft ever built when it first flew in 1944, and was the largest aircraft produced by any of the Axis powers during World War II.
The Pratt & Whitney R-4360 Wasp Major is an American 28-cylinder four-row radial piston aircraft engine designed and built during World War II. At 4,362.5 cu in (71.489 L) the largest-displacement aviation piston engine to be mass-produced in the United States, and at 4,300 hp (3,200 kW) the most powerful. It was the last of the Pratt & Whitney Wasp family, and the culmination of its maker's piston engine technology. The war was over before it could power airplanes into combat. It powered many of the last generation of large piston-engined aircraft before turbojets, but was supplanted by equivalent horsepower turboprops. Its main rival was the twin-row, 18-cylinder, nearly 3,350 cu in (54.9 l) displacement, up to 3,700 hp (2,800 kW) Wright R-3350 Duplex-Cyclone, first run some seven years earlier.
The Kawanishi H8K was a flying boat used by the Imperial Japanese Navy Air Service during World War II for maritime patrol duties. The Allied reporting name for the type was "Emily".
The Saunders-Roe A.36 Lerwick was a British flying boat built by Saunders-Roe Limited (Saro). It was intended to be used with the Short Sunderland in Royal Air Force Coastal Command but it was a flawed design and only a small number were built. They had a poor service record and a high accident rate; of 21 aircraft, 10 were lost to accidents and one for an unknown reason.
The Blohm & Voss BV 222 Wiking was a large, six-engined German flying boat of World War II. Originally designed as a commercial transport, it was the largest seaplane to attain production status during the war.
The Martin PBM Mariner was an American patrol bomber flying boat of World War II and the early Cold War era. It was designed to complement the Consolidated PBY Catalina and PB2Y Coronado in service. A total of 1,366 were built, with the first example flying on 18 February 1939 and the type entering service in September 1940.
The Martin JRM Mars is a large, four-engined cargo transport flying boat designed and built by the Martin Company for the United States Navy during World War II. It was the largest Allied flying boat to enter production, although only seven were built. The United States Navy contracted the development of the XPB2M-1 Mars in 1938 as a long-range ocean patrol flying boat, which later entered production as the JRM Mars long-range transport.
The Aviator is a 2004 American epic biographical drama film directed by Martin Scorsese and written by John Logan. It stars Leonardo DiCaprio as Howard Hughes, Cate Blanchett as Katharine Hepburn and Kate Beckinsale as Ava Gardner. The supporting cast features Ian Holm, John C. Reilly, Alec Baldwin, Jude Law, Gwen Stefani, Kelli Garner, Matt Ross, Willem Dafoe, Alan Alda, and Edward Herrmann.
The Short S.45 Seaford was a 1940s flying boat, designed as a long range maritime patrol bomber for RAF Coastal Command. It was developed from the Short S.25 Sunderland, and initially ordered as "Sunderland Mark IV".
The PB2Y Coronado is a large flying boat patrol bomber designed by Consolidated Aircraft, and used by the US Navy during World War II in bombing, antisubmarine, and transport roles. Obsolete by the end of the war, Coronados were quickly taken out of service. Only one known example remains, at the National Naval Aviation Museum at Naval Air Station Pensacola, Florida.
A cargo aircraft is a fixed-wing aircraft that is designed or converted for the carriage of cargo rather than passengers. Such aircraft usually do not incorporate passenger amenities and generally feature one or more large doors for loading cargo. Freighters may be operated by civil passenger or cargo airlines, by private individuals or by the armed forces of individual countries.
The Hughes Airport was a private airport owned by Howard Hughes for the Hughes Aircraft Company. It was located just north of the Westchester bluffs and district of Los Angeles, California, from 1940 until its closure in 1985. It was directly south of and along Jefferson Boulevard and Ballona Creek, the location of the present day planned community development of Playa Vista.
The Short Shetland was a British high-speed, long-range, four-engined flying boat built by Short Brothers at Rochester, Kent for use in the Second World War. It was designed to meet an Air Ministry requirement for a very-long range reconnaissance flying boat. The design used the company's experience with large scale production of the Short Sunderland. The end of World War II prevented the Shetland from entering production; it was the first aircraft designed with a 110 volt electrical system.
Sproat Lake is a lake on central Vancouver Island in British Columbia, Canada. It was known as Kleecoot by local indigenous people.
The Bréguet 890 Mercure was a late 1940s French cargo and passenger transport aircraft designed by Bréguet Aviation. Three variants were produced including a military variant called the Mars but none entered production.
The AVIC AG600 Kunlong is a large amphibious aircraft designed by AVIC and assembled by CAIGA. Powered by four WJ-6 turboprops, it is one of the largest flying boats with a 53.5 t (118,000 lb) MTOW. After five years of development, assembly started in August 2014, it was rolled out on 23 July 2016 and it made its first flight from Zhuhai Airport on 24 December 2017; it should be certified in 2021, with deliveries starting in 2022.
