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 eng ...

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 Los An ...

Douglas DC-1
The Douglas DC-1 was the first model of the famous American DC (Douglas Commercial) commercial transport aircraft series. Although only one example of the DC-1 was produced, the design was the basis for the DC-2 and DC-3, the latter of which being one of the most successful aircraft in the history of aviation. Design and development Development of the DC-1 can be traced back to the 1931 crash of a TWA airliner, a Fokker F-10 trimotor in which a wing failed, probably because water had seeped between the layers of the wood laminate and dissolved the glue holding the layers together. Following the accident, the Aeronautics Branch of the U.S. Department of Commerce placed stringent restrictions on the use of wooden wings on passenger airliners.Friedman and Friedman ''Aeroplane Monthly'' May 2001, pp. 34–40.O'Leary ''Aeroplane Monthly'' February 2007, p. 71. Boeing developed an answer, the 247, a twin-engined all-metal monoplane with a retractable undercarriage, but their product ...

LOT Polish Airlines
LOT Polish Airlines, legally incorporated as Polskie Linie Lotnicze LOT S.A. (, ''flight''), is the flag carrier of Poland. Established in 1928, LOT was a founding member of IATA and remains one of the world's oldest airlines in operation. With a fleet of 75 aircraft as of 2021, LOT Polish Airlines is the 18th largest operator in Europe with over 120 destinations across Europe, Asia and North America. The airline was founded on 29 December 1928 by the Polish government during the Second Polish Republic as a self-governing limited liability corporation, taking over existing domestic airlines Aerolot (founded in 1922) and Aero (founded in 1925), and began operations on 1 January 1929. The first aircraft used by LOT were Junkers F.13 and Fokker F.VII with the inaugural international service to Vienna, Austria, beginning on 2 August 1929. Most of the destinations originate from its hub at Warsaw Chopin Airport. Since 2018, LOT has maintained two long-haul routes from Budapest Fer ...

MacRobertson Air Race
The MacRobertson Trophy Air Race (also known as the London to Melbourne Air Race) took place in October 1934 as part of the Melbourne Centenary celebrations. The race was devised by the Lord Mayor of Melbourne, Sir Harold Gengoult Smith, and the prize money of £15,000 was provided by Sir Macpherson Robertson, a wealthy Australian confectionery manufacturer, on the conditions that the race be named after his MacRobertson confectionery company, and that it was organised to be as safe as possible. A further condition was that a gold medal be awarded to each pilot who completed the course within 16 days. The race was organised by an Air Race Committee, with representatives from the Australian government, aviation, and Melbourne Centenary authorities. The Royal Aero Club oversaw the event. The race ran from RAF Mildenhall in East Anglia to Flemington Racecourse, Melbourne, approximately . There were five compulsory stops, at Baghdad, Allahabad, Singapore, Darwin, and Charleville, ...

Carl Cover
Carl Anson Cover (26 April 1893 – 27 November 1944) was the chief test pilot and first to fly the Douglas Aircraft Company DC-1, DC-2, DC-3, DC-4, and the DC-5 airliners. Cover became Senior Vice President and general manager for Douglas Aircraft and later Vice President of Bell Aircraft. Early life Cover was born on 26 April 1893, to Hugh and Helen Cover in Roxbury, Pennsylvania.

Swissair
Swissair AG/ S.A. (German: Schweizerische Luftverkehr-AG; French: S.A. Suisse pour la Navigation Aérienne) was the national airline of Switzerland between its founding in 1931 and bankruptcy in 2002. It was formed from a merger between Balair and Ad Astra Aero (''To the Stars''). For most of its 71 years, Swissair was one of the major international airlines and known as the "Flying Bank" due to its financial stability, causing it to be regarded as a Swiss national symbol and icon. It was headquartered at Zürich Airport, Kloten. In 1997 the Swissair Group was renamed SAirGroup (although it was again renamed Swissair Group in 2001), with four subdivisions: SAirlines (to which Swissair, regional subsidiaries Crossair and Belair, and leasing subsidiary FlightLease belonged), SAirServices, SAirLogistics, and SAirRelations. By the late 1990s, Swissair was burdened by over-expansion as a result of the controversial " Hunter Strategy". The crash of Swissair Flight 111 in 1998, ...

Douglas B-18 Bolo
The Douglas B-18 Bolo is an American heavy bomber which served with the United States Army Air Corps and the Royal Canadian Air Force (as the Digby) during the late 1930s and early 1940s. The Bolo was developed by the Douglas Aircraft Company from their DC-2, to replace the Martin B-10. By 1940 standards, it was slow, had an inadequate defensive armament, and carried too small a bomb load. A B-18 was one of the first USAAF aircraft to sink a German U-boat, on 22 August 1942 in the Caribbean. By 1942, surviving B-18s were relegated to antisubmarine, training and transport duties. Design and development In 1934, the United States Army Air Corps requested for a twin-engine heavy bomber with double the bomb load and range of the Martin B-10 then entering service. During the evaluation at Wright Field the following year, Douglas offered its DB-1. It was competing against the Boeing Model 299 (later developed into the Boeing B-17 Flying Fortress) and Martin 146. While the Boeing de ...

Trans World Airlines
Trans World Airlines (TWA) was a major American airline which operated from 1930 until 2001. It was formed as Transcontinental & Western Air to operate a route from New York City to Los Angeles via St. Louis, Kansas City, and other stops, with Ford Trimotors. With American Airlines, American, United Airlines, United, and Eastern Air Lines, Eastern, it was one of the "Legacy carrier#Defunct legacy carriers, Big Four" domestic airlines in the United States formed by the Air Mail scandal, Spoils Conference of 1930. Howard Hughes acquired control of TWA in 1939, and after World War II led the expansion of the airline to serve Europe, the Middle East, and Asia, making TWA a second unofficial flag carrier of the United States after Pan American World Airways, Pan Am. Hughes gave up control in the 1960s, and the new management of TWA acquired Hilton Worldwide, Hilton International and Century 21 Real Estate, Century 21 in an attempt to diversify the company's business.

United States Army Air Corps
The United States Army Air Corps (USAAC) was the aerial warfare service component of the United States Army between 1926 and 1941. After World War I, as early aviation became an increasingly important part of modern warfare, a philosophical rift developed between more traditional ground-based army personnel and those who felt that aircraft were being underutilized and that air operations were being stifled for political reasons unrelated to their effectiveness. The USAAC was renamed from the earlier United States Army Air Service on 2 July 1926, and was part of the larger United States Army. The Air Corps became the United States Army Air Forces (USAAF) on 20 June 1941, giving it greater autonomy from the Army's middle-level command structure. During World War II, although not an administrative echelon, the Air Corps (AC) remained as one of the combat arms of the Army until 1947, when it was legally abolished by legislation establishing the Department of the Air Force.
