Boeing KC-97L Stratofreighter. Photo. Characteristics.


A type: Chetyrehdvigatelny transport aircraft / tanker aircraft

Capacity: A crew of six or seven people and passengers to 134

The C-97 «Stretofreyter» (Stretofreighter - stratospheric truck), built on the basis of bomber-29, was more than a "Superfortess", thanks to the addition of the second fuselage larger diameter, mounted on top of an existing structure - the scheme has received pilots US Air Force nickname «double bubble» («double-bubble").

Three pre-production aircraft received a copy of the US Air Force designation XC-97, and although they were ordered concurrently with the aircraft in-29 1942 in January, the last type was a priority. At the end of the year 1944, Boeing began flight test aircraft XC-97, which was followed by an order for aircraft C-50 97A. Although the aircraft was designed to carry passengers and freight, but only after the war in the air tanker role to support the newly established Strategic Air Command, he achieved the greatest success.

It was built at least 811 refueling aircraft CS-97 in three different versions (E, F and G). Combining a roomy cargo hold of the aircraft and refueling revolutionary system «Flying Boom» («Flying Rod"), the company "Boeing" aircraft allowed "Stretotanker» (Stratotanker - stratospheric tanker) to pump huge amounts of fuel burgeoning fleet of bombers of the Strategic Air Command. And those same moments have allowed aircraft to live up to 1970-ies in the face of a possible reduction. Today, a handful of civilian aircraft operated by carriers in Central and South America and in North America they are operated as an aircraft fire.
