The first commercial Skymaster did Denver-Los Angeles in five hours

To Western Air Lines, which 22 years ago took delivery of Douglas Aircraft Co.'s first airline plane, the M-2 biplane, went the first post-war commercial version of the C-54 to come off the Douglas production line at Santa Monica, Calif. The company expects to put the ship in use soon over the Denver-Los Angeles route over which it made a survey flight a few days ago. Flight time to Denver from the West Coast, was approxi-mately five hours. The plane is shown here against a backdrop of California mountains as it appeared on a Los Angeles-San Francisco survey flight last week.
