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.

At least 811 KS-97 refueling aircraft were built in three different modifications (E, F and G). By combining the capacious cargo hold of the aircraft and the revolutionary Flying Boom refueling system, Boeing allowed the Stratotanker (Stratosphere Tanker) to pump huge amounts of fuel to the burgeoning fleet of Strategic Air Command bombers. And the same moments allowed the plane to live up to 1970-ies in conditions of possible reduction. Today, a handful of these aircraft are operated by civil cargo carriers in Central and South America, and in North America they are operated as fire planes.
