The Boeing 707 is a mid-size, narrow-body four-engine jet airliner that was manufactured by Boeing Commercial Airplanes from 1958 to 1979. Versions of the aircraft have a capacity of 140 to 202  passengers and a range of 3,680 to 3,735 nautical miles. Developed as Boeing's first jet airliner, the 707 features a swept-wing design with podded engines.  the 707 is generally credited with ushering in the Jet Age. Although the distinction of being the first jetliner in service goes to the De Havilland Comet aircraft, the 707 was the first to be commercially successful world-wide and dominated passenger air transport in the 1960s, and remaining common throughout the 1970s. It  established Boeing as one of the largest manufacturers of passenger  aircraft, and led to the later series of aircraft with "7x7" designations. The subsequent 727, 737, and 757 also share elements of the 707s fuselage design.

During its service career, the 707 has been used in a variety of roles, including domestic, transcontinental, and transatlantic operations. The 707 has also been used for cargo and military  applications. A convertible passenger / freighter model, the 707-320C,  entered service in 1963, and passenger 707s have been modified to  freighter configurations. Military derivatives include the E-3 Sentry airborne reconnaissance aircraft and the C-137 Stratoliner VIP transports. During the 707s production run, Boeing produced and  delivered a total of 1,011 aircraft, including the slightly smaller 720 series, in addition to over 800 military versions being produced. As of July 2013, only 10  examples of the 707 remain in airline service round the world.
