FS2002 ProjectAI UAL United Airlines Boeing B741. The 747-100 entered commercial service in 1970. Initially, engines only were available from Pratt & Whitney, but by 1975 engines also were available from General Electric and Rolls-Royce. Boeing delivered 250 of the 747-100s, the last in 1986. Boeing built two versions of the 747-100 passenger airplane, one of which had a higher payload capacity and was known as the -100B. The 747-100 also was available as a short-range airplane, which had a modified body structure to accommodate a greater number of takeoffs and landings. This model typically was used by airlines on short flights with a high-passenger capacity, as many as 550. Boeing also built the 747-100SP (special performance), which had a shortened fuselage and was designed to fly higher, faster and farther non-stop than any B747 model of its time.
