Lockheed Model 12 Electra Junior

The Lockheed 12 was an eight-seat, six passenger all-metal transport designed for use by smaller airlines and private owners. Developed as a scaled-down version of the Lockheed 10 Electra, the prototype made its first flight on June 27, 1936, piloted by Marshall Headle.

British Airways Ltd. ordered two Electra Juniors in 1939. Although ostensibly acquired for civilian purposes, these aircraft were modified for aerial photography and used by Sidney Cotton to track Axis military activity on the eve of World War II.

A modified Electra Junior was used by the NACA as a testbed for "hotwing" deicing technology.

A total of 130 Electra Juniors were built. At the time of Pearl Harbor this aircraft had outsold the competing Beech 18 by 2-1, and Lockheed had over two dozen unfilled orders. In order to concentrate on more vital and advanced wartime aircraft, Lockheed turned the unfilled orders over to Beechcraft, who eventually built many thousands of their Model 18.

The Electra on screen

An Electra Junior appeared in the film Casablanca. Wartime security precautions prevented shooting at an airport at night, so a cardboard cutout stood in for a real airplane in many shots.

Two Electra Juniors appeared as stand-ins for a model 10-E Electra in the 1976 TV movie Amelia Earhart.

    FAQ

    I don't see my comments any more!

    Please note that each page has it's own comment entry. So, if you enter a comment i.e. on the B-747, you will only see it on that related page.

    General comments are accessed via the "BLOG En" button.

    Comments are moderated, so please allow some delay before they appear, specially if you are outside Europe.

    Menus are developing below the page, because they are too long!

    But they remain accessible, for example by scrolling the mouse wheel, or with your finger (on the menu) on a smartphone or tablet.

    I see adds on all videos.

    Use a good free add remover software.

    The site is loading random pages at startup.

    We think it is a good way to bring back the memory of aircraft, persons or events sometimes quite forgotten.

    HELP PAGE

    Why this site?

    Discovery

    This website is dedicated to one's aeronautical passion (which I hope we share) and was realised mainly as an educationnal tool. Knowing that, you'll notice that each new visit brings random topics for the purpose of making new discoveries, some achievements or characters certainly not deserving the oblivion into which they have sometimes fallen.

    By these pages, we also want to pay tribute to all those who gave at one time or another, their lives or health in the name of freedom, aeronautical security or simply our comfort.

    Centralisation

    Internet is full of websites dedicated to aviation, but most are dedicated to subjects or periods that are very limited in space or time. The purpose of this site is to be as general as possible and thus treats all events as well as characters of all stripes and times while putting much emphasis on the most significant achievements.

    The same years saw birth of technologies like photography and cinema, thus permitting illustration of a large part of important aeronautical events from the start. Countless (and sometimes rare) media recently put online by enthousiasts finally give us access to these treasures, but the huge amount of information often makes things a little messy. A centralization effort is obviously most needed at this level.

    All persons who directly or indirectly contributed to the achievement or posting of such documents are here gratefully acknowledged.

    General

    Fluid website

    This site automatically fits the dimensions of your screen, whether you are on a desktop computer, a tablet or a smartphone.

    Bilingual website

    You can change the language by clicking on the flag in the upper left or via "Options" in the central menu. Of course, the videos remain in the language in which they were posted ...

    Browser compatibility

    The site is not optimized, or even designed to run on older browsers or those deliberately deviating from standards. You will most probably encounter display issues with Internet Explorer. In this case, it is strongly recommended installing a modern (and free!) browser that's respecting the standards, like Firefox, Opera, Chrome or Safari.

    Cookies and Javascript

    This site uses cookies and JavaScript to function properly. Please ensure that your browser is configured accordingly. Neither of these technologies, or other means shall in no case be used on the Site for the retention or disclosure of personal information about its Visitors. See the "Legal" page for more on this subject.

    Website layout

    Left menus

    Because of the lack of space on smartphones and small tablets, these menus are hidden. Everything is nevertheless accessible via the main menu option, located between the video and photo sections. This menu is placed there for compatibility reasons with some browsers, which play the videos over the menus.

    "Search" and "Latest" :
    The link "In Titles" restricts the search to the titles of different forms. Use this option if you are looking for a plane, a constructor, a pilot or a particular event that could have been treated as a subject.

    The link "In Stories" will bring you to a search in all texts (the "Story" tab) and will take more time. The search term will appear highlighted in green when opening the corresponding story.

    Would you believe, "Timeline" will show all subjects in chronological order.

    "Random" will reload the entire page with a new random topic.

    The bottom section keeps you abreast of the latest five entries. New topics are added regularly. Don't hesitate to come visit us often : add bookmark.

    Blogs and Comments central section

    Under the photos section comes the comments tabs window :

    You can enter general comments in your own language via one of the two buttons on the left (BLOG EN and BLOG FR). Note that these buttons are accessible regardless of the language to allow some participation in the other language.

    All comments are subject to moderation and will be published only if they comply with the basic rules of decorum, while remaining relevant to the purpose of this site.

    The third tab allows you to enter comments on the shown topic and is bilingual. Personal anecdotes, supplements and other information questions will take place here.

    The "Story" tab shows the explanatory texts. They are most often taken from Wikipedia, a site where we participate regularly.

    The "Data" tab is reserved for list of features and specifications.

    Right menus

    On a smartphone, the lack of space is growing and this menu is moved to the bottom of the page to give priority to videos and pictures.

    The top right icons are links to videos posted by third parties (on their own responsabilities) or by ourselves. The link below these icons will take you to the channel of the one who posted the video. Feel free to suggest other videos if you think they are of some interest (Use the BLOG button or the "Contact" link).
