Boeing's aircraft factory in Everett, Wash., is one of the world's largest. CNET ventures inside, where the company builds 747, 767, 777, and 787 aircraft.
Welcome to Everett
Everett, Wash.--Thirty miles north of Seattle sits Boeing's immense factory, where it builds 787, 777, 747, and 767 aircraft. At 472.3 million cubic feet (4.3 million square feet or 98.3 acres), it's the largest building by volume in the world.
Boeing first completed the Everett site in 1967, because it had no facility large enough in the Seattle area to build its new 747 jumbo jet. With 25 747 orders from Pan Am on the books, time was short and the building was constructed as the first 747 mock-up was constructed on the factory floor. Boeing had to move 4 million cubic yards of earth to build the plant and construct the steepest standard gauge railway in the Northern Hemisphere. Even at the time of completion, Boeing set records for building size, at 205.6 million cubic feet.
The building is so big that clouds actually formed inside until an air circulation system was installed. Today there's no air conditioning or heating system. Instead, the factory is warmed by the 1 million ceiling lights and cooled (if it ever gets that hot in Everett) by opening the doors.
In 1980 the factory expanded to 298.2 cubic feet for 767 production, and it reached its present size in 1993 when Boeing started building the 777. More than 30,000 people are employed at the factory (working in three shifts around the clock) and about 110,000 people visit each year to take the public tour. Here you can see the factory's giant doors, which feature the largest digital graphics mural in the world (more than 100,00 square feet).
On the public balcony, graphics show the stages of an airliner's production. After the various sections of an aircraft arrive on the production line (many of the parts are built elsewhere), final assembly can begin. Systems are installed, the fuselage sections and wings are joined together, tests are run, and engines and interior fittings are installed. The plane then leaves the factory for painting, test flights, and delivery to the airline.
Here is a 787 destined for Japan Airlines (JAL). Since the Dreamliner is made of composite materials, its skin doesn't have the same sea green color that Boeing's metal aircraft wear before painting. Above the factory floor are offices and conference rooms, while a network of 26 cranes hangs from the ceiling. The cranes run on 39 miles of track and can lift up to 40 tons.
Further down the production line are 787s destined for Ethiopian Airlines and All Nippon Airways (ANA). ANA is the launch customer for the 787 and will receive its first commercial delivery by the third quarter of this year. Initial delivery was set for 2008, but the complexity of the aircraft, a machinists strike, and supplier shortages caused repeated delays.
