Boeing 7x7 From Wikipedia, the free encyclopedia (Redirected from Boeing 7 series) Jump to: navigation, search Boeing 7x7, or simply 7x7, is a term used to describe Boeing's "7-Series" of airliners, the Boeing 707, 717, 727, 737, 747, 757, 767, 777, and 787. It is comparable to Airbus's A300 to A380 range of aircraft. Note that the "7X7" (with an uppercase X) designation was confusingly the original designation for the Boeing 767 before its entry into service. Other similar designations included the 7N7 ( Boeing 757 ) , 7E7 (Boeing 787) and the Boeing 7J7.
