About Boeing 747
The Boeing 747 is a long-range wide-body airliner designed and manufactured by Boeing Commercial Airplanes in the United States between 1968 and 2023. After the introduction of the 707 in October 1958, Pan Am wanted a jet 2+1/2 times its size, to reduce its seat cost by 30%. In 1965, Joe Sutter left the 737 development program to design the 747. In April 1966, Pan Am ordered 25 Boeing 747-100 aircraft, and in late 1966, Pratt & Whitney agreed to develop the JT9D engine, a high-bypass turbofan. On September 30, 1968, the first 747 was rolled out of the custom-built Everett Plant, the world's largest building by volume. The 747's first flight took place on February 9, 1969, and the 747 was certified in December of that year. It entered service with Pan Am on January 22, 1970. The 747 was the first airplane called a "Jumbo Jet" as the first wide-body airliner.
Boeing 747-200 variant
While the 747-100 powered by Pratt & Whitney JT9D-3A engines offered enough payload and range for medium-haul operations, it was marginal for long-haul route sectors. The demand for longer range aircraft with increased payload quickly led to the improved -200, which featured more powerful engines, increased MTOW, and greater range than the -100. A few early -200s retained the three-window configuration of the -100 on the upper deck, but most were built with a ten-window configuration on each side. The 747-200 was produced in passenger (-200B), freighter (-200F), convertible (-200C), and combi (-200M) versions.

After launching the -200 with Pratt & Whitney JT9D-7 engines, on August 1, 1972, Boeing announced that it had reached an agreement with General Electric to certify the 747 with CF6-50 series engines to increase the aircraft's market potential. Rolls-Royce followed 747 engine production with a launch order from British Airways for four aircraft. The option of RB211-524B engines was announced on June 17, 1975. The -200 was the first 747 to provide a choice of powerplant from the three major engine manufacturers. In 1976, its unit cost was US$39M (208.8M today).

A total of 393 of the 747-200 versions had been built when production ended in 1991. Of these, 225 were -200B, 73 were -200F, 13 were -200C, 78 were -200M, and 4 were military. Iran Air retired the last passenger 747-200 in May 2016, 36 years after it was delivered. As of July 2019, five 747-200s remain in service as freighters.
