After the war Boeing developed the Model 367, a military transport based on the B-29 bomber. Its civilian counterpart was the Model 377 Stratocruiser. The C-97 had a double-lobe fuselage consisting of two intersecting circular sections, so that the 74-foot-long upper deck had a larger diameter. Cargo was loaded through large clamshell-type doors in the belly of the aircraft using a built-in ramp and a hoist. Its wings, engine gear and other parts were similar to the B-29.
