The 747-8 Intercontinental is the only jetliner in the 400- to 500-seat market, stretched 5.6 m (18.3 ft) from the 747-400 to provide 467 seats in a three-class configuration and a 14,815-km (8,000-nmi) range. Using 787-technology engines, the airplane will be quieter, produce lower emissions, and achieve better fuel economy than any competing jetliner. Boeing launched the airplane on November 14, 2005, with firm orders for 18 Freighter versions of the 747-8.
