Originally, Boeing planned to build 250 727s. However, after being shown to the world, they proved so popular (especially after the larger 727-200 model, which carried up to 189 passengers, was introduced) that a total of 1,832 were produced at the Renton, Wash., plant. Variants included a convertible passenger-cargo model with a Quick Change (QC) option -- seats and galleys attached to removable pallets.
