Pratt & Whitney faced difficulties with the JT9D design during the Boeing 747 test program. Engine failures during the flight test program resulted in thirty aircraft being parked outside the factory with concrete blocks hanging from the pylons, awaiting redesigned engines. Boeing and Pratt & Whitney worked together in 1969 to solve the problem.
This Boeing 747-451 [Note 1] was the first 747-400, an improved version of Boeing's successful jumbo jet. The aircraft was the 696th Boeing 747 built and carried manufacturer's serial number 23719. [citation needed] Final assembly began at the Boeing Everett Factory, the longtime site of 747 production, in September 1987. Assembly was completed ...
A shorter derivative of the 747-100, the SP was developed to target two market requirements.

Until the arrival of the 767, Boeing lacked a mid-sized wide-body to compete in this ...
N747GE is a Boeing 747 aircraft that was used by General Electric Aircraft Engines (now known as GE Aerospace) as a testbed for several of the companies jet engines between 1992 and 2017, including the GE90 for the Boeing 777, at the time, the world’s largest jet engine.
After the 747 test flights, Boeing re-registered the aircraft as N1352B in July 1970 to explore missions beyond its original design specifications. These missions were primarily military, including using N1352B as a refuelling tanker for the Lockheed SR-71 Blackbird and the Boeing B-52 Stratofortress. Unfortunately, the idea of using the Boeing ...
