The Lockheed L-10 Electra was built by Lockheed 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.

Two Lockheed L-10 Electras are preserved in the Museum of Transport and Technology.
