The 132-inch (3,350 mm) wide fuselage of the Dash 80 was large enough for four-abreast (two-plus-two) seating (in the manner of the Stratocruiser). Answering customers demands and under Douglas competition, Boeing soon realized that this would not provide a viable payload, so decided to widen the fuselage to 144 in (3,660 mm) to allow five-abreast seating and use of the KC-135's tooling.[12] However, Douglas Aircraft had launched its DC-8 with a fuselage width of 147 in (3,730 mm). The airlines liked the extra space and six-abreast seating, and so Boeing was obliged to increase the 707's width again to compete, this time to 148 in (3,760 mm).
