The four-engine Boeing 707, together with the Soviet Tu-104, the French Sud Aviacion Caravelle and the British de Havilland DH.106 Comet, is one of the first jet airliners in the world produced for passenger air travel. Also starting with Boeing 707, the foundations were laid for the domination of jet planes of the American company Boeing Commercial Airplanes in the market of passenger air travel. Depending on the modification, the range of 707s can be from 4650 to 10550 kilometers. Different versions of the Boeing 707 aircraft are able to accommodate up to 189 passengers in their cabin.

According to Boeing 707 its concept, is a narrow-body, four-engine plane shaped monoplane low-wing arrow shaped, under which are located in nacelles turbojets.

The prototype for the whole family became 707-x plane Boeing 367-80, also known as the Dash-80. Construction Boeing 367-80, 1952 year began, and has already 14 May 1954 year's plane was. The length of the finished aircraft was 39,97 meters in span in 39,88 meters. To build Boeing 367-80 spent about 16 million. The flight of the prototype took place on July 15 1954 years.

Later, the prototype name was changed to Model-707. Since the beginning of the flight tests, the company "Boeing", from the US Air Force received an order to develop a jet aircraft tanker. For the basis of this project was chosen an elongated version of the aircraft Model-707. The prototype aircraft tanker received the designation Model-717. Serial aircraft will also receive the designation C-135 Stratolifter and KS-135 Stratotanker.

But as for an airliner for passenger traffic, then Boeing had a competitor in the face of the jet plane Douglas DC-8, produced by the American firm McDonnell Douglas. For this reason, Boeing had to upgrade its project. The new aircraft received the designation Boeing 707-120. On this plane, the cross section and length of the fuselage was increased. This allowed to place three chairs in the same row. Due to this passenger capacity was increased. The length of the aircraft Boeing 707-120 is now 44,07 meters. The Pratt & Whitney JT3D-6 engines were installed on the airliner with an 60,02 kN thrust. Orders for the Boeing 707-120, began to arrive in the middle of 1955. The Pan American airline became the first customer of the new air liner. For the first time, this aircraft took to the sky 20 December 1957 of the year. Regular passenger flights, on domestic American flights, up to 5000 kilometers, Boeing 707-120 began to operate from August 1958 year.

Boeing 707 SalonIn December, 1955 also began work on building aircraft for intercontinental flights. The main customer of the new transatlantic aircraft was the Pan American. The aircraft received the designation Boeing 707-320. This model has an increased fuselage, thanks to which the length of the Boeing 707-320 is 46,61 meters. The wing span and volume of the fuel tanks were also increased. Initially, Pratt & Whitney JT4-3 71,5 kN engines were installed on the aircraft. The first flight of the Boeing 707-320 made 11 January 1959 of the year. After certification in August 1959, the aircraft began to enter the airline. At the beginning of 1962, the first flight of the Boeing 707-320 with Pratt & Whitne JT3D-3 engines was made. Later on the aircraft were used engines Pratt & Whitney JT3D-7 power 84,4 kN.

Version of the Boeing 707-320, has become the most popular aircraft of the entire family of 707-s. This airliner in economy class, capable of accommodating up to 189 passengers. When the two-class layout in its cabin can be placed 147 passenger seats. The range of its flight is more than nine thousand kilometers.

In addition, various modifications were manufactured passenger aircraft designed to transport, freight and military purposes.

Manufacture of aircraft Boeing 707 was finally discontinued in 1978 year. Over the entire period of production units issued 1010 aircraft Boeing 707.
