Is the 777X actually the newest Boeing plane?
While the 777X is a derivation from the older 777 Classic family of airplanes, it is, in fact a brand new airplane, similar to the difference between the 747-8 and the 747 Classic line or the F/A-18E/F Super Hornet compared with the F/A-18A-D series. Based on that and the rollout date of the 777X, it would be BCA’s latest airplane.
