Lockheed 14 Super Electra

Designed to compete against the DST/ DC-2/DC-3 series being developed by the Douglas company, the Lockheed 14 Super Electra failed, by reason of its smaller capacity, to present any significant competition. Of the same general configuration as the earlier Lockheed 10 Electra, it differed primarily by having a much deeper fuselage accommodating a maximum of 14 passengers, a mid-set wing, and introduced such advanced features as integral fuel tanks in the wing, Fowler-type trailing-edge flaps, fully-feathering propellers and, at a later stage of production, fixed wing slats. These improvements, combined with powerful engines and high wing loading, gave the Super Electra excellent performance but, by comparison with the important and larger-capacity Douglas DC-3, it was less efficient in operation, with the result that only 112 were built by Lockheed. First flown in prototype form on 29 July 1937 and certificated on 15 November 1937, initial deliveries were made shortly afterwards. By far the majority of the Super Electras were exported and, in addition, a total of 119 was licence-built in Japan for use by the Imperial Japanese Army. These, powered by 671kW Mitsubishi Ha-26-l radial engines, were designated Army Type LO Transport and were later allocated the Allied code name 'Thelma'.

For an intriguing story about the Lockheed 14, read Chapter 21 of F.W.Winterbotham's book "The Ultra Spy". The title of the chapter, "Spy Plane", would suit its adaptation into a screenplay about the aircraft's imaginative use, for a very original pre-WW2 film, set in 1939.

I spent a lot of time polishing a corporate L-14 back in the late 50's in Pgh,Pa. Belonged to Mesta Machine Co., and had an NC# registered between the one H. Hughes flew around the world(loaded with pingpong balls for buoyancy)...and the one that had been ordered for Amelia Earhart to use after her around-the-world flight. Actually got to fly as co-pilot a few times, and was talked through a landing! Sometimes wonder where this aircraft ended up at.....

An armed version of this airliner became the highly-successful Lockheed Hudson.

Hello. I am interested in the instrument panel of the Lockheed 14 Super Electra. I'm having difficulty finding a picture with enough detail that I can identify the layout. Do you happen to know where such pictures might be on the web?

I am researching the Lockheed Hudson aircraft as flown in England by RAF Coastal Command in the 1940's.My uncle, S/L William (Bill) Coulson who flew Lockheed 14 Super Electras for Trans Canada Airlines ( TCA ) in 1938 in Canada and was based at No.1 (Coastal) Operational Training Unit (OTU) at RAF Silloth in England in 1940,was training pilots to fly Hudsons.Based on his experience with TCA, Bill preferred the 'wheeler landing'( land on main wheels and then drop the tail wheel) over the '3-point' landing ( nose up attitude with all three wheels touching down at same time) advocated by the RAF.The landing instructions for the Electra/Hudson were included in the Lockheed 'Book' or Operation Manual I believe.Could you please tell me how and where I can access a copy of this document, or specifically the landing instructions for the Electras and/or Hudsons.Please acknowledge receipt of this information request....I thank you and look forward to your prompt response.
