Introduced by Pan American World Airways in 1970, the Boeing 747-100 was the first of a new breed of jetliner, the “wide-body,” which ultimately revolutionized the airline industry. The 747 main cabin was wide enough to seat ten abreast and could carry up to 450 passengers. The new wide-body was twice the size of the Boeing 707 shown here. The Boeing 707 carried up to 189 passengers. Image: Pan American World Airways brochure, Boeing 747, 1969. Gift of Thomas G. Dragges. 2015.165.883 This image was posted on September 30, 2020.
