Credit to Joe Davis for finding this link to a promotional movie about The Bell Bomber factory. It was made in 1944 by Bell Aircraft and show's the early days of what's now Lockheed Martin in Marietta. USAF not only created an aircraft factory, they also created a sub-culture affecting housing, education, shopping, recreation and socialization. Do you remember when Hwy 41 was a two lane road? Can you imagine seeing Hwy 41 & AF Plant 6 surrounded by fields, pastures & farmland? Ever seen a dual assembly line for an aircraft the size of a B-29? Take a look at the link below.
