The Douglas DC-1 first flew on 1 July 1933 at Clover Field, Santa Monica, California. Only one was built, flying mainly in TWA insignia. After service during the Spanish Civil War, it was written-off following a take-off accident near Malaga, Spain, in December 1940. From it were developed the famous DC-2 and DC-3, which established the reputation of Douglas as an airliner manufacturer.
