Passage: As Airbus progressed with its A3XX study, Boeing offered a 747 derivative as an alternative in 2000; a more modest proposal than the previous -500X and -600X that retained the 747's overall wing design and add a segment at the root, increasing the span to 229 ft (69.8 m). Power would have been supplied by either the Engine Alliance GP7172 or the Rolls-Royce Trent 600, which were also proposed for the 767-400ERX. A new flight deck based on the 777's would be used. The 747X aircraft was to carry 430 passengers over ranges of up to 8,700 nmi (10,000 mi, 16,100 km). The 747X Stretch would be extended to 263 (80.2 m) long, allowing it to carry 500 passengers over ranges of up to 7,800 nmi (9,000 mi, 14,500 km). Both versions were also based on the 747X.
