James Baker's idea for the ultimate high-altitude camera was the C model that would have a 240-inch focal length. In December 1954, he made preliminary designs for folding the optical path using three mirrors, a prism, and an f/20.0 lens system. Before working out the details of this design, however, Baker flew to California in early January 1955 to consult with Kelly Johnson about the weight and space limitations of the U-2's payload compartment. Despite every effort to reduce the physical dimensions of the C camera, Baker needed an additional six inches of payload space to accommodate the bigger lens. When he broached this subject to Johnson, the latter replied, "Six more inches? I'd sell my grandmother for six more inches!" $ ^{20} $ Not linked to a story yet.
