The aircraft rolled off the assembly line on October 17, 1969 and went into operation with Pan American World Airlines. GE purchased the aircraft in 1992.

“We are very proud of the length of reliable service the flying testbed has provided,” said Dom Pitocco, plant leader at GE’s Victorville Flight Test Operation. “The aircraft is a living relic, being the primary commercial engine test aircraft for GE’s top-performing and best-selling engines over the past two decades.”

The flying testbed, a first-generation 747-100 model, is the oldest version of the 747 still flying in the United States today and the fifth oldest in the world. The aircraft has flight tested GE and CFM International* engines of various sizes and thrust capabilities, from the CF34 engines for regional jets to the world’s largest, most powerful engine, the GE90-115B.

GE has flown the aircraft more than 600 cycles and 2,500 test hours, bringing its lifetime total to more than 18,000 cycles and 88,000 flight hours.
