The Douglas DC-7 was a propeller-driven airliner built from 1953 to 1958. It was the last propliner built by Douglas just before the advent of the jet age. The later DC-7C variants were one of the first airliners able to reliably make westward non-stop flights against the prevailing wind from Europe to New York.

The Douglas DC-7 was directly developed from the successful design of the DC-6B, a piston-engine airliner. This newer model aimed to enhance and expand upon the features and capabilities of its predecessor.

The Douglas DC-7 boasts impressive specifications across various dimensions and weights. It has a wingspan stretching 117 feet and a length measuring 108 feet. Standing tall, its height is 28 feet.

When it comes to weight, this aircraft has a gross weight of 122,200 pounds and an empty 66,305 pounds. These specifications contribute to its robust performance and capacity in the skies.

The Douglas DC-7 can reach a maximum speed of 410 mph with a cruising speed of 360mph. It is powered by four robust Wright R-3350 Turbo Compound engines, each delivering a formidable 3,250 horsepower.

Eighteen airlines collectively acquired a total of 338 Douglas DC-7 aircraft.
