Known during development as the short-body 747SB, the 747SP was designed to meet a 1973 joint request from Pan American World Airways

Trijet
A Trijet is an aircraft powered by three jet engines. Early twin-jet designs were limited by the FAA's "60-minute rule", whereby the flight path of twin-engined jetliners was restricted to within 60 minutes' flying time from a suitable airport, in case of engine failure. In 1964 this rule was...

 airliners.

The 747SP first entered service with Pan Am in 1976. The aircraft was later acquired by VIP and government customers. While in service, the 747SP set several aeronautical performance records, but sales did not meet expectations, and production ultimately totaled 45 aircraft.

Development

The idea for the 747SP came from a request by Pan Am for a 747 variant capable of carrying a full payload non-stop on its longest route between New York and Tokyo
Tokyo

 in the world. The aircraft was launched with Pan Am's first order in 1973, and the first example delivered in 1976.

A shorter derivative of the 747-100, the SP was developed to target two market requirements. The first was a need to compete with the DC-10
McDonnell Douglas DC-10
The McDonnell Douglas DC-10 is a three-engine widebody jet airliner manufactured by McDonnell Douglas.

 while maintaining commonality with the 747, which in its standard form was too large for many routes. Boeing lacked a mid-sized wide-body to compete in this segment. The second market requirement was an aircraft suitable for the ultra-long-range routes emerging in the mid-1970s following the joint request. These routes needed not only longer range, but also higher cruising speeds. Boeing could not afford to develop an all-new design, instead opting to shorten the 747 and optimize it for speed and range, at the expense of capacity. Production of the 747SP ran from 1976 to 1983.

Design

Apart from having a significantly shorter fuselage and one fewer cabin door per side, the 747SP differs from other 747 variants in having simplified flaps

Flaps are normally hinged surfaces mounted on the trailing edges of the wings of a fixed-wing aircraft to reduce the speed an aircraft can be safely flown at and to increase the angle of descent for landing without increasing air speed. They shorten takeoff and landing distances as well as...

s, rather than the smaller triple-slotted flaps of standard 747s. The SP was also the first— and until the introduction of the Boeing 777-200LR the only—Boeing wide-body with a wingspan greater than the length of the fuselage.
The SP could accommodate 230 passengers in a 3-class cabin or 331 in a (303 economy, 28 business) 2-class cabin, and a maximum of 440 passengers in one class. Originally designated 747SB for "short body", it later was nicknamed "Sutter's balloon" by employees after 747 chief engineer Joe Sutter

 entered service in 1989. Despite its technical achievements, the SP never sold as well as Boeing hoped. Increased fuel prices in the mid 1970s to early 1980s, the SP's heavy wings, expensive cost, reduced capacity, and the increased ranges of forthcoming airliners were some of the many factors that contributed to its low sales. Only 45 were built and of those remaining, most are used by operators in the Middle East

. However, some of the engineering work on the 747SP was reused with the development of the 747-300 and 747-400. In the 747SP, the upper deck begins over the section of fuselage that contains the wingbox, not ahead of the wingbox as is the case with the 747-100 and 747-200. This same design was used in the 747-300 and 747-400 resulting in a stretched upper deck.

Operators

Forty-five 747SP aircraft were built between 1974 and 1989. As of December 2008, 17 are still flying, 16 have been scrapped, and 12 are in storage, awaiting salvage or on display in museums.
