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 design, developed by a team led by Don Palmer, was a scaled-up version of the original Model 10 Electra, with passenger seating increased from 10 to 14. It was intended to compete commercially with the contemporary Douglas DC-2 and the Boeing 247. The first Model 14 flew on July 29, 1937, piloted by Marshall Headle. Early 14's used the Pratt & Whitney R-1690 Hornet engine; later the Wright R-1820 Cyclone 9 was offered as an option.
Lockheed built a total of 114 Model 14s; another 119 were built under license in Japan by the Tachikawa Aircraft Company under the designation Tachikawa Type LO Transport AircraftThelma. Another 121 were built by Kawasaki Aircraft Company under the designation Kawasaki Type 1 cargo transporter. The type 1 cargo's fuselage was lengthened by 1.4m (4ft 7in), enabling the fitting of larger cargo doors.[1]
In Japan during the late 1930s and early 1940s, in common with most large economies of the time, research was being conducted into pressurised cabins for high-altitude flight. In similar fashion to the Lockheed XC-35, in the United States, Tachikawa incorporated a pressurised cabin into new forward and centre fuselage sections for one of the locally built Lockheed Type LO Transport Aircraft. The resulting research aircraft was given the long designation Tachikawa-Lockheed Type-B high altitude research aircraft and the company designation Tachikawa SS-1. The first conversion was completed in May 1943, re-engined with 2x 810kW (1,080hp)Mitsubishi Ha-102 14-cylinder radial engines. The two conversions carried out a brief flight testing programme.
In 1938, British prime minister Neville Chamberlain, after signing the Munich Agreement, returned to London Heston Airport on board a British Airways Lockheed 14, and was famously photographed beside the aircraft (registration G-AFGN[2]),[3] showing to the crowd the signed document, which he would later that day describe as bringing "peace for our time".[citation needed]
Record-breaking flights
In May 1938, a team of aviators of the Polish airline LOT, made up of Wacław Makowski, director of LOT and first pilot, Zbigniew Wysiekierski, second pilot, Szymon Piskorz, mechanic and radionavigator, Alfons Rzeczewski, radio-navigator and Jerzy Krassowski, assistant, accomplished an experimental flight from the United States to Poland. This flight was carried out on board one of the aircraft bought by LOT, manufactured by Lockheed in California, a Lockheed Model 14H Super Electra (of which the Polish registration was SP-LMK.[4]). The crew took off from Burbank (Los Angeles) where these aircraft were manufactured, and after a tour of South America, flew the Atlantic from Brazil to West Africa en route to Warsaw. A poster celebrating the flight can be seen in a US Library of Congress/Matson Archive photo of the LOT/Imperial Airways Sales office in Jerusalem about 1939.[5]
The distance covered was of 15,441mi (24,850km; 13,418nmi). They flew via the cities of Mazatlan, Mexico City, Guatemala, and Panama, then via the South American cities of Lima, Peru; Santiago, Chile; Buenos Aires, Argentina; and Rio de Janeiro and Natal in Brazil. They flew across the South Atlantic to Dakar, Senegal, in Africa and then to Casablanca, Tunis, and then on to Rome, Italy. The final leg of the flight brought them to Warsaw, Poland. The flying time was 85 hours between 13 May and 5 June. The overflight of the Atlantic - from Natal to Dakar - lasted 11 hours and 10 minutes (1,908mi/3,070km).[6] This feat by Polish aviators marked the history of air communication on a world level. (Prior to this flight airliners were delivered across the Atlantic as deck cargo on ships [7]).
Howard Hughes flew a Super Electra (NX18973) on a global circumnavigation flight. With four crewmates (Harry Connor, copilot; Tom Thurlow, navigator; Richard Stoddart, engineer; and Ed Lund, mechanic), the Lockheed 14 took off from Floyd Bennett Field in New York on July 10, 1938. The flight, which circled the narrower northern latitudes, passed through Paris, Moscow, Omsk, Yakutsk, Fairbanks, Alaska and Minneapolis before returning to New York.[8][9] The total distance flown was 14,672mi (23,612km) and total time was 3 days, 19 hours, 17 minutes.[citation needed]
A single 14-H (c/n 1401) converted with a bulged cabin roof and large freight door for carriage of bulky loads, later re-converted to 14-H for airline use in Brazil and Nicaragua.
Another export version, a.k.a. 14-G3B, powered by 2x 900hp (670kW)GR-1820-G2B engines. With the exception of four aircraft delivered to Romania, all WG3Bs were delivered to Japan, either to Tachikawa Hikoki K.K. for re-sale or direct to the operator Nihon Hikoki K.K. (Greater Japan Airways Co. Ltd).

Eastern Air Lines, also colloquially known as Eastern, was a major American airline from 1926 to 1991. Before its dissolution, it was headquartered at Miami International Airport in an unincorporated area of Miami-Dade County, Florida.

The Lockheed L-188 Electra is an American turboprop airliner built by Lockheed. First flown in 1957, it was the first large turboprop airliner built in the United States. Initial sales were good, but after two fatal crashes that led to expensive modifications to fix a design defect, no more were ordered. With its unique high power-to-weight ratio, huge propellers and very short wings, large Fowler flaps which significantly increased effective wing area when extended, and four-engined design, the airplane had airfield performance capabilities unmatched by many jet transport aircraft even today—particularly on short runways and high field elevations. Jet airliners soon supplanted turboprops for many purposes, and many Electras were modified as freighters. Some Electras are still being used in various roles into the 21st century. The airframe was also used as the basis for the Lockheed P-3 Orion maritime patrol aircraft.
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.

Japan Airways Co.Ltd was the national airline of the Empire of Japan during World War II.
The Ilyushin Il-12 was a Soviet twin-engine cargo aircraft, developed in the mid-1940s for small and medium-haul airline routes and as a military transport.
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.
British Overseas Airways Corporation (BOAC) was the British state-owned airline created in 1939 by the merger of Imperial Airways and British Airways Ltd. It continued operating overseas services throughout World War II. After the passing of the Civil Aviation Act 1946, European and South American services passed to two further state-owned airlines, British European Airways (BEA) and British South American Airways (BSAA). BOAC absorbed BSAA in 1949, but BEA continued to operate British domestic and European routes for the next quarter century. The Civil Aviation Act 1971 merged BOAC and BEA, effective 31 March 1974, forming today's British Airways.
