Had this stored in the designer for a year, so I've brought it out and updated it with the TWA livery and a few more details.

The Boeing 747SP (for Special Performance) is a shortened version of the Boeing 747 wide-body airliner, designed for a longer range. It is the highest flying subsonic passenger airliner, with a service ceiling of 45,100 feet (13,700 meters). Boeing needed a smaller aircraft to compete with the McDonnell Douglas DC-10 and Lockheed L-1011 TriStar tri-jet wide-bodies, 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. As of September 2022, there were just three Boeing 747SPs still in active service, with 18 more stored and one preserved. The remaining 23 were either scrapped, otherwise destroyed, or abandoned.

The 747SP was the longest-range airliner available until the 747-400 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, high cost, and 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. In the 747SP, the upper deck begins over the section of fuselage that contains the wing box, not ahead of the wing box (as is the case with the 747-100 and 747-200). This same design was used in the 747-300 and newer 747-400, resulting in a stretched upper deck.
