United Airlines 727 mahogany wooden airplane model. The first flight of the 727-200 occurred on July 27 1967, with certification granted in late November that year. The -200 was placed into service by launch customer Northeast Airlines (this airline was later acquired by Delta) the following month, by which time total 727 orders for both models had exceeded 500.
The 727-200 helped broaden the sales appeal of the 727 considerably and snared significant sales. However the 200 was restricted by its relatively short range, due to it having the same fuel capacity as the 727-100, so Boeing developed the increased range Advanced 727-200. First flown in March 1972 changes introduced on the Advanced model included increased fuel capacity, and thus range, the option of more powerful engines, quieter engine nacelles and strengthened structure. The Advanced remained the primary 727-200 production model until production ceased in 1984.
