Boeing RC-1
The Boeing RC-1, short for "Resource Carrier 1", was a design for an enormous cargo aircraft intended to haul oil and minerals out of the northern reaches of Alaska and Canada where ice-free ports were not available. It was optimized for short-haul missions only, carrying cargo to locations for loading onto ships, trains or pipelines. Depending on the role, the design was nicknamed "Brute Lifter" or "Flying Pipeline". The basic design had a rectangular wing spanning almost , was powered by 12 Pratt & Whitney JT9D engines, and had 56 wheels in the main landing gear. A total of of cargo was carried in two under-wing pods and fuselage. The RC-1 would have been roughly twice the size and mass of the Antonov An-225 Mriya, the largest aircraft built, but would have carried about five times the payload.〔The maximum takeoff weight of the ''Mriya'' is about ; the RC-1 was MTOW, and carried of ''cargo''.〕 The RC-1 was designed in the early 1970s. The rapid increase in jet fuel prices after 1973 doomed the project to be uneconomical. ==History==
