The Boeing 747 was the first aircraft produced at Boeing’s Everett factory.
Boeing built the Everett plant in Washington to assemble the 747, whose enormous size required a new production facility. Construction began in 1966, and the factory’s main assembly building became one of the world’s largest enclosed buildings by volume.
The 747 program drove the development of the site, which later became a major center for Boeing wide-body production. Boeing subsequently assembled the 767, 777, and 787 at Everett, although production assignments have changed over time.
The factory is sometimes confused with Boeing’s Renton facility, which has been associated with major narrow-body programs such as the 737. Everett’s identity is particularly linked with large wide-body aircraft and the 747’s pioneering production requirements.
