The Boeing C-97 Stratofreighter is a long-range heavy military cargo aircraft developed from the B-29 and B-50 bombers. Design work began in 1942, the first of three prototype XC-97s flew on 9 November 1944 and the first of six service-test YC-97s flew on 11 March 1947.

The C-97 Stratofreighter is a long-range heavy military cargo aircraft based on the B-29 bomber. The prototype’s first flight was in 1944. 888 C-97s were built, 816 of them made as KC-97 tankers (aerial refuelers); the KC-97L aircraft had two additional J47 …
