Something my dad told be about that plane: "If you took all the drawings required to design the 747, and put them in a 747, it would never get off the ground." He worked at Boeing in the early 60s, and had a lot of cool stories about how the place ran. Traffic signals synced to the shift changes (on 7-minute intervals) for all employees at the plant. The insane process efficiency required to use a pencil and paper to design a project that complex. Etc.
