Fact Sheet
The Boeing Company announced in 1966 that it would build the world's largest jet airliner, the 747. This would require the company to construct an equally impressive manufacturing complex.
The complex is recognized by the Guinness Book of World Records as the largest building in the world by volume.
The building has grown over the years to enclose 472 million cubic feet of space (13.3 million cubic meters). Its footprint covers 98.3 acres (39.8 hectares) and houses assembly for Boeing twin-aisle airplanes -- the 747, 767, 777 and 787 Dreamliner.
Boeing began officially conducting Everett factory tours in 1968, the year we rolled out the first 747. During 1998, we celebrated our 30th anniversary and welcomed our two millionth visitor to the Tour Center.
We welcomed the three millionth visitor nearly ten years later, in November 2007, and celebrated the 40th anniversary of the Everett site in 2008.
In 2005, the new Future of Flight Aviation Center & Boeing Tour complex was completed, replacing the old tour center built in the early 1980s.
In 1968, more than 39,000 visitors toured the factory where the largest airplane in the world was being built in the largest building in the world. Forty years later, about 110,000 people visit the Boeing factory annually.
Some of the Everett factory's most notable visitors include: U.S. President Bill Clinton; U.S. Vice President Al Gore; Russian President Boris Yeltsin; Chinese President Jiang Zemin; President Soeharto of Indonesia; Prime Minister Paul Keating of Australia; Prime Minister Mahathir bin Mohamad of Malaysia; President Ion Iliescu of Romania; Prince Phillipe of Spain; President Meri of Estonia; the late King Hussein of Jordan; His Royal Highness Prince Andrew, The Duke of York; and President Michal Kovac of Slovakia.
