Lockheed 10 Electra

Lockheed's first major move towards becoming a significant manufacturer of transport aircraft came with design of the Lockheed 10 Electra. Providing accommodation for 10 passengers, the Electra was a cantilever low-wing monoplane of all-metal construction, with retractable tailwheel landing gear and a tail unit incorporating twin fins and rudders. Powered by two Pratt & Whitney Wasp Junior SBs, the prototype was flown for the first time on 23 February 1934, and was followed by 148 production aircraft. The Electra entered service during 1934, initially with Northwest Airlines, and in the late 1930s was used by eight American operators. By the time that the USA became involved in World War II, however, few remained in national airline service for the rapid growth in air travel had already shown these small-capacity aircraft to be uneconomical. In addition to those built for the home market, Electras were exported to Argentina, Australia, Canada, Chile, Colombia, Japan, New Zealand, Poland, Romania, USSR, UK, Venezuela and Yugoslavia. Small numbers also saw service in the Spanish Civil War and with the outbreak of World War II the type was impressed for service with the Royal Air Force and Royal Canadian Air Force. Use of the Electra by small civil operators continued after the war, as it was cheap to buy and operate, but few remained in service after the late 1960s.

union airways flew lockheed 10s in new zealand

In the mid sixties I got some right seat time in a L12A which while similiar to a Beech 18 was slightly larger. It was purported to be Juan Trippe's (Pan-Am)persomal a/c in the late thirties. Great flyer and fast for the time. This was with Metcalf Aviation at the old Sacramento Muni (SAC)

I had the pleasure of working on sevaral 10A's while imployed by White-Crow Inc. in the early 70's. We maintained the aircraft for PBA in Naples, Fl. They also had 12A's

The long wire antennae that h. van asten is referring to was removed by Earhart and Noonan prior to their disappearance. (Source: Wikipedia.org)

@ Capurso. The radio antenna of NR16020 ran from a mast on the cabin roof to both tailplanes. There was no belly aerial present.

Al Capurso, 24.12.2010

The design of the radio antenna laying underneath the plane was a serious flaw and probably contributed to the loss of Amelia Earhart and Fred Noonan. Evidence indicates the antenna snapped off on a bumpy runway upon takeoff for the last leg of the ill-fated trip and Earhart could no longer receive radio transmissions.

You said "these small-capacity aircraft (where) uneconomical", then you said "Use of the Electra by small civil operators continued after the war, as it was cheap to buy and operate".

Can you say which New Zealand Airline used the Lockheed 10 Electra in 1937/38? A picture would be much appreciated.

Karl, 29.04.2009

Do you know what model was used in the movie "Dive Bomber" with Errol Flynn and Fred MacMurray, circa 1941?

Do you have any comments about this aircraft ?
