Nose sections of Boeing B-29 Superfortress aircraft, Boeing Airplane Company, Wichita, Kansas

View of nose sections of Boeing B-29 Superfortress bomber aircraft at the Boeing Airplane Company's Wichita, Kansas plant. Label on back: "Trouble for Japan! Two rows of sleek, glistening nose sections on Boeing B-29 Superfortresses are shown here on the assembly lines of Boeing Airplane Company's Wichita, Kansas plant. In the left background are huge double bomb bay sections while in the distance may be seen nearly-completed B-29's on their way to join sister ships which have gone before and are now at distant bases carrying out their assignments against Japan. A systematic schedule of production cycles whereby sections making up the Superfortress advance one position in a mass movement taking place at the end of each six hours and forty minutes has placed bomber assembly lines on a clocklike precision basis at Wichita. The movement of the production floor starts at exactly the same instant, each section going forward one position. The system not only unifies all phases of production and eliminates confusion but also establishes at all times the exact location and amount of progress on every B-29 unit. It takes about two minutes to complete the mass movement on the assembly floor. As the first producing plant in one of the largest production programs of the war, Boeing's Wichita Division has been turning out the big bombers for more than a year. Switching over from the manufacture of B-17 Flying Fortresses, Boeing's plants in Seattle and Renton, Washington are now producing the Superfortress, and the Bell plant in Georgia and the Martin plant in Nebraska are also building the Boeing-designed B-29."
