Boeing rolled out the first 747-100 from the Everett, WA factory on Sept. 30, 1968. The Boeing 747 was the world's first jumbo jet--doubling the size of the 707. Since 1970, the Boeing 747 has been produced in more than 20 versions, including freighter, convertibles, combis and special-use models. Known as the "Queen of the Skies," the 747 is the most recognized airplane in the world.
