For this reason, the company «Boeing» have to upgrade your project. The new aircraft received the designation Boeing 707-120. This plane has been increased and the length of the fuselage section. This will place the three seats in the same row. Due to this was increased passenger capacity. The length of the aircraft Boeing 707-120 44,07 now amounts meters. On the airliner were installed engines Pratt & Whitney JT3D-6 60,02 with the thrust of kN. Orders for Boeing 707-120, began to arrive in the middle of 1955 years. The first customer of the new airliner was the airline «Pan American». For the first time the aircraft took to the skies in December 20 1957 years.

This model has an enlarged fuselage, whereby the length of Boeing 707-320 46,61 of meters. Wingspan and volume of fuel tanks have also been increased. Initially, the plane was fitted Pratt & Whitney engines JT4A-3 71,5 capacity of kN. The first flight of Boeing 707-320 11 made in January 1959 years. After certification in August 1959, the aircraft began to enter the airline. At the beginning of the year 1962 made its first flight Boeing 707-320 with engines Pratt & Whitne JT3D-3. Later, on the plane were used engines Pratt & Whitney JT3D-7 84,4 kN capacity.

Version Boeing 707-320, became the most popular aircraft of the entire family of 707-s. This airliner in economy class, is able to accommodate up to 189 passengers.
