Boeing says that the first two 777X test aircraft are now on the low-rate initial production line. Once assembled, the fuselages will have their new composite wings attached.
The Boeing 777X is a new series of the long-range wide-body twin-engine Boeing 777 family that is under development by Boeing Commercial Airplanes.
The 777X is to feature GE9X new engines, new composite wings with folding wingtips, a denser cabin, and technologies from the Boeing 787.
