In reality, unpainted Boeing airliners feature a glossy emerald green color during the assembly process, a striking and unusual color scheme. Most modern airliners are primarily constructed out of an aluminum alloy, and the green color is a coat of primer paint. The primer is applied during the production of various aircraft components, which are then shipped to final assembly still wearing this green color.
Individual components of an aircraft are constructed worldwide by various suppliers and contractors. The degree of component outsourcing varies by aircraft; Spirit AeroSystems assembles the Boeing 737 fuselage in Wichita, Kansas, while Boeing assembles the 777 fuselagein Everett, Washington.
Overall, Boeing traditionally assembles most aircraft components in-house, but the 787 features by far the highest level of outsourcing. Boeing completes the final assembly of the 737 in Renton, Washington, while the 767 and 777 are completed in Everett. Boeing assembled the 707, 727, and 757 in Renton, while it formerly built the 747 in Everett.
The Boeing 787, meanwhile, previously had a final assembly line in Everett, but Boeing shut it down in 2021 as it consolidated 787 production in North Charleston, South Carolina. Once the fuselage is complete and placed on the final assembly line, workers install interior systems such as electrics, plumbing, and hydraulics. Workers then attach the radome and doors before attaching the aircraft's wings.
