Douglas DC-7

The Douglas DC-7 was an advanced development of the

DC-6B piston-engine airliner. It was introduced by American Airlines on its New York–Los Angeles route in November 1953 and was the first airliner to provide nonstop transcontinental service in both directions.

The fastest transport aircraft in service, the DC-7 cruised at 580 kilometers (360 miles) per hour. A total of 338 DC-7s of all types were purchased by 18 different airlines. Like other piston-engine airliners, it was made obsolete by the introduction of turbine-engine Boeing 707s and Douglas

DC-8s. Some DC-7s later served as cargo and charter planes.

This nose section is from American Airlines’ Flagship Vermont, which carried about 130,000 passengers in its nearly 13,500 hours aloft.
