The Lockheed L-10 Electra was Lockheed's first experiment in metal aircraft production, and was built to compete with the Ford Trimotor. It made its first flight in 1934.

Amelia Earhart piloted an Electra on her final around-the-world flight in 1937.

While many Electras were impressed into the military during World War II (as the C-36), they started to disappear after the end of the war, by which point they were long obsolete.
