boeing c-97 stratofreighter - choose a jigsaw puzzle to solve

The Boeing C-97 Stratofreighter was a long-range heavy military cargo aircraft developed from the B-29 and B-50 bombers. Design work began in 1942, the first of 3 prototype XC-97s flew on 9 November 1944 (none saw combat ), and the first of 6 service- test YC-97s flew on 11 March 1947. All these (9) were based on the 24ST alloy structure and Wright R-3350 engines of the B-29 but with a larger-diameter fuselage upper lobe (making a figure of eight or 'double-bubble'section) and they had the B-29 vertical tail with the gunners position blanked off. The first of 3 heavily revised YC-97A incorporating the re-engineered wing ( higher strength 75ST alloy), taller vertical tail and larger Pratt and Whitney R-4360 engines of the B-50 bomber , flew on 28 January 1948 and was the basis of the subsequent sole YC-97B, all production C-97s, KC-97s and civilian Stratocruiser aircraft . Between 1944 and 1958 , 888 C-97s in several versions were built, 811 being KC-97 tankers. C-97s served in the Berlin Airlift, the Korean War , and the Vietnam War . Some aircraft served as flying command posts for the Strategic Air Command, while others were modified for use in Aerospace Rescue and Recovery Squadrons (ARRS). The C-97 Stratofreighter was developed towards the end of World War II by fitting an enlarged upper fuselage onto a lower fuselage and wings which were essentially the same as those of the B-29 Superfortress with the tail , wing , and engine layout being nearly identical. It was built before the death of Boeing president Philip G. Johnson . It can be easily distinguished from the 377 Stratocruiser by the " beak " radome beneath the nose and by the flying boom and jet engines on later tanker models.
