27 January 2020: Boeing 777X which was equipped with two GE9X engines completed its maiden flight. The aircraft departed from Paine Field in Everett, Washington.
"On behalf of the GE team, congratulations to Boeing on the first flight of the 777X.

"We are proud to be the power under the wings of the 777X and provide this state-of the-art aircraft with GE's advanced technology."
Since 2013, GE Aviation has been designing and testing the GE9X. In preparations for Boeing 77Xs's maiden flight, GE has carried out 72 test flights of the GE9X totalling more than 400 hours on its Boeing 747 flying test bed in Victorville, CA. Till now, the GE9X programme has completed over 4,100 hours of ground and air testing, as well as 6,500 cycles.

"The GE9X is the most fuel-efficient jet engine that GE has ever produced, operating at 10 per cent lower fuel consumption than competing engines."
