Narrative: Curtiss C-46 1957-1966
By 1956 Delta's cargo service had grown 724 percent since launching in 1946 with Douglas C-47 freighters. When the new C-46 fleet went into operation in 1957, Delta increased its all-cargo lift by 600 percent.
Main cabin was eight feet longer than a standard railroad box car.
Extra large doors were "large enough to load a Cadillac automobile without scratching the paint job," according to Delta.
