Boeing 747
The idea for the 747 was thought of in the 1960s. Jets like the Boeing 707 and Douglas DC-8 had made it easy to travel long distances. Juan Trippe from Pan American World Airways (Pan Am), asked Boeing to build a plane which was more than two times bigger than the Boeing 707. At this time, airports were very busy. Trippe thought that a big plane could help make them quieter.
