DZ203
DZ203, a Boeing 247 airliner, was among the most important single aircraft used in the development of various airborne radar and blind landing systems. It is particularly notable as the first aircraft to perform a completely automatic approach and landing, in January 1945. The aircraft was originally built in 1933 as construction number 1726 and entered service with United Airlines as NC13344. United later sold off their fleet of 247's, and NC13344 was part of a set of eight that was purchased by the Royal Canadian Air Force (RCAF) on 10 August 1940 for light transport duties. NC13344 arrived at RCAF Station Dartmouth in September, where it was registered as RCAF serial number 7655. In August 1940, during the Tizard Mission, the Canadian National Research Council (NRC) was introduced to the British work on radars. The Mission continued on to Washington, DC where the cavity magnetron was revealed and US agreed to build versions of the AI Mk. VIII radar. Their initial SCR-520 s ...

Air-to-Surface Vessel Radar
Radar, Air-to-Surface Vessel, or ASV radar for short, is a classification used by the Royal Air Force (RAF) to refer to a series of aircraft-mounted radar systems used to scan the surface of the ocean to locate ships and surfaced submarines. The first examples were developed just before the opening of World War II and they have remained a major instrument on patrol aircraft since that time. It is part of the wider surface search radar classification, which includes similar radars in ground and ship mountings. The first ASV was developed after the accidental detection of wharves and cranes while testing an air-to-air radar in 1937. For a variety of reasons, ASV was easier to develop than the air-to-air variety of the same systems, and the first operational use of the Mark I followed in early 1940. A cleaned-up and repackaged version, ASV Mark II, replaced it at the end of the year, but the system was not widespread until late in 1941. ASV was useful for detecting U-boats at night, ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the World War II by country, vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies of World War II, Allies and the Axis powers. World War II was a total war that directly involved more than 100 million Military personnel, personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Air warfare of World War II, Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the Atomic bombings of Hiroshima and Nagasaki, only two nuclear weapons ever used in war. World War II was by far the List of wars by death toll, deadliest conflict in hu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Douglas DC-3
The Douglas DC-3 is a propeller-driven airliner manufactured by Douglas Aircraft Company, which had a lasting effect on the airline industry in the 1930s to 1940s and World War II. It was developed as a larger, improved 14-bed sleeper version of the Douglas DC-2. It is a low-wing metal monoplane with conventional landing gear, powered by two radial piston engines of . (Although most DC-3s flying today use Pratt & Whitney R-1830 Twin Wasp engines, many DC-3s built for civil service originally had the Wright R-1820 Cyclone.) The DC-3 has a cruising speed of , a capacity of 21 to 32 passengers or 6,000 lbs (2,700 kg) of cargo, and a range of , and can operate from short runways. The DC-3 had many exceptional qualities compared to previous aircraft. It was fast, had a good range, was more reliable, and carried passengers in greater comfort. Before the war, it pioneered many air travel routes. It was able to cross the continental United States from New York to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Douglas DC-2
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. Design and development In the early 1930s, fears about the safety of wooden aircraft structures drove the US aviation industry to develop all-metal airliners. United Airlines had exclusive right to the all metal twin-engine Boeing 247; rival TWA issued a specification for an all-metal trimotor. The Douglas response was more radical. When it flew on July 1, 1933, the prototype DC-1 had a robust tapered wing, retractable landing gear, and two 690 hp (515 kW) Wright radial engines driving variable-pitch propellers. It seated 12 passengers. Douglas test pilot Carl Cover flew the first test flight on May 11, 1934, of the DC-2 which was longer than the DC-1, had more powerful ...

Air Mail Scandal
The Air Mail scandal, also known as the Air Mail fiasco, is the name that the American press gave to the political scandal resulting from a 1934 congressional investigation of the awarding of contracts to certain airlines to carry airmail and to the use of the U.S. Army Air Corps to fly the mail. In 1930, during the administration of President Herbert Hoover, Congress passed the Air Mail Act of 1930. Using its provisions, Postmaster General Walter Folger Brown held a meeting with the executives of the top airlines, later dubbed the "Spoils Conference", in which the airlines effectively divided among themselves the air mail routes. Acting on those agreements, Brown awarded contracts to the participants through a process that effectively prevented smaller carriers from bidding, resulting in a Senate investigation. The Senate investigation resulted in a citation of Contempt of Congress against William P. MacCracken Jr., on February 5, 1934, the only action taken against any ...

Boeing Air Transport
United Airlines is the third largest airline in the world, with 86,852 employees (which includes the entire holding company United Airlines Holdings) and 721 aircraft. It was the brainchild of William Boeing and emerged from his consolidation of numerous carriers and equipment manufacturers from 1928 to 1930. History Beginnings United Airlines was the creation of aviation pioneer William Boeing, who started out in the airplane business in 1916. His Boeing Airplane Company, as it was then called, achieved the first international postal delivery in 1919, and he went on to establish United Aircraft Corp. in 1928. It was this UAC that acquired mail and passenger service operator Pacific Air Transport on January 1, 1928, then renamed Boeing Aircraft & Transport Co., merged with Pratt & Whitney Aircraft in early 1929 to form United Aircraft and Transport Corporation (UATC).
