The forerunner of all Douglas Commercials. The sole DC-1 on the day of its first flight from Santa Monica - 1 July 1933. Note the initial aerodynamic strut between fuselage and engine cowling - soon deleted. At date of image, the aircraft was owned by Douglas Aircraft. Quickly passed to TWA for airline tests. From Douglas 60 years ago.
