The Boeing Factory. The worlds largest building by volume.

If you plan on visiting the Seattle area, You must visit the Boeing factory, The building itself is the largest building in the world by volume and Boeing's tour is one of the country's most popular factory tours.

The Boeing factory tour allows you to see the flight line where the 747, 767, 777 and the new 787 are built. On the tour you will walk through part of the largest building in the world by volume — some 472,000,000 cubic feet.
Boeing delivered its 3000th widebody airplane from its Everett, Washington, site on August 27th 2007. The airplane was a 777-200ER (Extended Range) model that was delivered to Korean Air.
Over the years, the 3,000 widebody airplanes assembled at the Everett site have established a strong track record. Combined, the 747, 767 and 777 have completed more than 34.5 million flights through June 2007.
They have logged approximately 148 million flight hours or nearly 17,000 years of flight time. The airplanes have flown approximately 71 billion nautical miles (131 billion kilometers), which is the equivalent of flying around the world 3.3 million times .The 3,000th-delivery milestone comes just nine years after the Everett site celebrated its 2,000th delivery — a 747-400 taken by British Airways May 15, 1998. The plant’s 1,000th widebody delivery was a 767-300ER delivered to Scandinavian Airlines on Aug. 14, 1989. Currently, more than 80 percent of the airplanes built at the Everett site — approximately 2,610 airplanes — are in service around the world.

Boeing are now producing the 787 Dreamliner, this is the first all-new plane made by Boeing in the last 12 years.
Strangely enough, While there aren't many changes on the outside, the 787 has drastic changes in the inside. They used alternative materials like carbon composite materials and 15 percent titanium to make it lighter, therefore it will consume less fuel, the final cost will become cheaper, and of course, it won't create as much pollution as other planes.
The largest model of the Boeing 787 has space for 330 people and prices can go from $146 million to $200 million.

This aircraft wasn't produced by Boeing to compete with the airbus A380 but Boeing believe that the market shows that people want reduced airfares on city to city routes rather than hub to hub routes that the A380 provides. With the A380 well into production now, Its only a matter of time before we find out who can win the battle for the skies. Just remember that the winner of the air wars could be whoever gets the contract to build the next generation aircraft for space travel.
