About the Boeing 747SP

The Boeing 747SP (for Special Performance) is a shortened version of the Boeing 747 widebody airliner, designed for a longer range.
Boeing needed a smaller aircraft to compete with the McDonnell Douglas DC-10 and Lockheed L-1011 TriStar trijet widebodies, introduced in 1971/1972. Pan Am requested a 747-100 derivative to fly between New York and the Middle East, a request also shared by Iran Air, and the first order came from Pan Am in 1973.

The variant first flew on July 4, 1975, was approved by the Federal Aviation Administration on February 4, 1976, and entered service that year with Pan Am.

The SP is 47ft (14m) shorter than all other 747 variants. Its main deck doors are reduced to four on each side to compensate for its lower capacity. The vertical and horizontal tailplane are larger and its wing flaps have been simplified. With a 700,000lb (320t) MTOW, it can fly 276 passengers in three classes over 5,830nmi (10,800km).
One 747SP was modified into the Stratospheric Observatory for Infrared Astronomy (SOFIA).
The last airliner was delivered in 1987; some were converted to transports of heads of state.
Sales did not meet the expected 200 units, and only 45 aircraft were ultimately produced.
