For comparison, some of the earliest GE90 engines aboard Boeing 777s kicked out 'just' 74,000 pounds. Airliners are growing ever bigger to haul more people per flight, which means they need ...
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.

General Electric used its 747-100 testbed in the 1990s for the GE90 which powers the Boeing 777-300ER, 777-200LR and 777F. GE and competitor Rolls-Royce were selected by Boeing to power its new 787. GE Aviation's offering is the GEnx, a development of the GE90. The engine was also the exclusive power plant on the Boeing 747-8.
