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 [[Lockheed Model 10 Electra|Model 10 Electra]], the Model 14 was also developed into larger, more capable civil and military versions.

==Design and development==
The design, developed by a team led by Don Palmer, was a scaled-up version of the original [[Lockheed Model 10 Electra|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 Aircraft''' ''Thelma''.
Another 121 were built by [[Kawasaki Aerospace Company|Kawasaki Aircraft Company]] under the designation Kawasaki Type 1 cargo transporter. The type 1's cargo fuselage was lengthened by {{convert|1.4|m|ftin|abbr=on}}, enabling the fitting of larger cargo doors.<ref>[http://military.sakura.ne.jp/ac/ki56.htm "Kawasaki Type 1."] ''sakura.ne.jp'' Retrieved: June 16, 2010.</ref>

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 Aircraft Company|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 {{convert|1080|hp|kW|abbr=on|order=flip}} [[Mitsubishi Ha-102]] 14-cylinder radial engines. The two conversions carried out a brief flight testing programme.

==Operational history==
The Model 14 entered commercial service with [[Northwest Airlines]] in the US in October 1937. Aircraft were exported for use by [[Aer Lingus]] of Ireland, [[British Airways Ltd (1935–39)|British Airways]] and [[KLM]] of the Netherlands. The Model 14 was the basis for development of the [[Lockheed Hudson]] maritime reconnaissance and [[light bomber]] aircraft operated by the [[Royal Air Force]], [[USAAF]], [[United States Navy]] and many others during [[World War II]].{{citation needed|date=December 2022}}

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 {{Airreg|G|AFGN}}),<ref name=Higham2016>{{cite book|title=Britain's Imperial Air Routes, 1918 to 1939: The story of Britain's overseas airlines |date=2016 |publisher=Fonthill |url=https://books.google.com/books?id=SQfzDQAAQBAJ|isbn=978-1-78155-370-1|edition=Revised|pages=160–161}}</ref> showing to the crowd the signed document, which he would later that day describe as bringing "[[peace for our time]]".{{citation needed|date=December 2022}}

===Record-breaking flights===
In May 1938, a team of aviators of the Polish airline [[LOT Polish Airlines|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.<ref>Coates, Ed. [http://www.edcoatescollection.com/ac5/ROW%20Europe/SP-LMK.html "SP-LMK  Lockheed 14-H."] ''edcoatescollection.com''. Retrieved: February 19, 2010.</ref>). 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.<ref>[https://www.flickr.com/photos/74784995@N00/2442043468/sizes/o/ "LOT Poster Historic Flight."] ''flickr.com''.

The distance covered was of {{convert|15,441|mi|km nmi|abbr=on}}. 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, Rio Grande do Norte|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 (1,908&nbsp;mi/3,070&nbsp;km).<ref>''Po wielkim locie doświadczalnym P.L.L. "Lot"''.

[[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.<ref name="Noah">{{cite book |last1=Dietrich |first1=Noah |last2=Thomas |first2=Bob |title=Howard, The Amazing Mr. Hughes |date=1972 |publisher=Fawcett Publications, Inc. |location=Greenwich |pages=136–139}}</ref><ref name="life19380725">[https://books.google.com/books?id=n08EAAAAMBAJ&pg=PA9 "A Rich Young Texan with a Poet's Face Gets Hero's Welcome on World Flight."] ''Life '', July 25, 1938, pp. 9–11, 14.
