The '''Lockheed Model 10 Electra''' is an American twin-engined, all-metal [[monoplane]] [[airliner]] developed by the [[Lockheed Aircraft Corporation]], which was produced primarily in the 1930s to compete with the [[Boeing 247]] and [[Douglas DC-2]]. The type gained considerable fame after being flown by [[Amelia Earhart]] and [[Fred Noonan]] on their ill-fated around-the-world expedition in 1937.

==Design and development==
[[File:Kelly-Johnson Electra.jpg|thumb|left|[[Clarence "Kelly" Johnson]] is testing an Electra model with single vertical tail and forward-sloping windshield in the [[University of Michigan]]'s wind tunnel.]]

Some of Lockheed's wooden designs, such as the [[Lockheed Model 9 Orion|Orion]], had been built by [[Detroit Aircraft Corporation]] with metal fuselages. However, the Electra was Lockheed's first all-metal and twin-engined design by [[Lloyd Stearman]]<ref>{{cite web|title=Lloyd Stearman|url=http://www.nationalaviation.org/stearman-lloyd/|publisher=National Aviation Hall of Fame|access-date=22 May 2013|archive-date=6 August 2013|archive-url=https://web.archive.org/web/20130806060456/http://nationalaviation.org/stearman-lloyd/|url-status=dead}}</ref><ref>{{harvnb|Phillips|2006|p=26}}</ref> and [[Hall Hibbard]]. The name [[Electra (star)|Electra]] came from a star in the [[Pleiades]]. The prototype made its first flight on February 23, 1934, with [[Marshall Headle]] at the controls.<ref>{{harvnb|Gunston|1998|p=8}}</ref>

Wind-tunnel work on the Electra was undertaken at the [[University of Michigan]]. Much of the work was performed by a student assistant, [[Kelly_Johnson_(engineer)|Kelly Johnson]]. He suggested two changes be made to the design: changing the single tail to double tails (later a Lockheed trademark), and deleting oversized wing fillets. Both of these suggestions were incorporated into production aircraft.<ref>{{harvnb|Francillon|1987|p=117-118}}</ref> Upon receiving his master's degree, Johnson joined Lockheed as a regular employee, ultimately leading the [[Skunk Works]] in developing advanced aircraft such as the [[Lockheed SR-71 Blackbird]].

The Lockheed Electra was one of the first commercial passenger aircraft with retractable landing gear to come equipped with mudguards as standard equipment, although aircraft with fixed landing gear commonly had mudguards much earlier than this.<ref>[https://books.google.com/books?id=wt8DAAAAMBAJ&pg=PA523 "Mud Guards on Plane Wheels Protect Landing Gear."] ''Popular Mechanics'', April 1935, p. 523, (bottom-right).</ref>

==Operational history==
[[File:Lockheed 10B VH-ASM Marshall Aws Bankstown 4.10.70 edited-2.jpg|thumb|left|Lockheed 10B of Marshall Airways (Australia) in 1970, had been initially delivered to [[Ansett Airways]] in 1937]]

After October 1934, when the US government banned single-engined aircraft for use in carrying passengers or in night flying, Lockheed was perfectly placed in the market with its new Model 10 Electra. In addition to deliveries to US-based airlines, several European operators added Electras to their prewar fleets. In Latin America, the first airline to use Electras was [[Cubana de Aviación]], starting in 1935, for its domestic routes.

[[File:Lockheed 10A Electra flight deck.jpg|thumb|Flight deck of a Model 10A, which has been updated with a more modern instrument panel]]

Besides airline orders, a number of non-commercial civil operators also purchased the new Model 10.<ref name= "Winchester p. 188">Winchester 2004, p. 188.</ref> In May 1937, [[Dick Merrill|H. T. "Dick" Merrill]] and J. S. Lambie accomplished a round-trip crossing of the [[Atlantic Ocean]]. The feat was declared the first round-trip commercial crossing of that ocean by any aircraft. It won them the [[Harmon Trophy]]. On the eastbound trip, they carried newsreels of the crash of the ''[[Hindenburg disaster|Hindenburg]]'', and on the return trip from the [[United Kingdom]], they brought photographs of the [[coronation of King George VI]]. [[Bata Shoes]] operated the Model 10 to ferry its executives between their European factories.

[[File:Amelia Earhart - GPN-2002-000211.jpg|thumb|Earhart and her customized Lockheed Electra]]
Probably the most famous use of the Electra was the highly modified Model 10E flown by [[Amelia Earhart]] and [[Fred Noonan]]. In July 1937, they disappeared over the central Pacific Ocean during an attempted round-the-world flight.<ref name= "Winchester p. 188"/>

Many Electras and their design descendants (the [[Lockheed Model 12 Electra Junior|Model 12 Electra Junior]] and [[Lockheed Model 14 Super Electra|Model 14 Super Electra]]) were pressed into military service during [[World War II]], for instance the [[United States Army Air Forces|USAAF]]'s '''C-36'''. By the end of the war, the Electra design was obsolete, although many smaller airlines and charter services continued to operate Electras into the 1970s.<ref name= "Winchester p. 188"/>

Electras were popular as private planes for royalty in Asia and Europe. In [[India]], the [[Maharaja of Jammu and Kashmir]] and the [[Maharaja of Jodhpur]] both purchased them for their personal use in 1937.<ref>''Straits Times'', 30 December 1937, Page 10.</ref>

The Electra was produced in several variants, for both civilian and military customers. Lockheed built a total of 149 Electras.
