Since 1989, two 747-200s have served as the symbol of American prestige, carrying the president and flying as Air Force One. Four more less glamorous ones, designated E4-Bs, rotate to shadow the president. These “doomsday airplanes” are equipped to serve as flying command posts in the event of a foreign attack or another catastrophe.

With a cruising speed of Mach 0.86, the 747-8 is as fast as any commercial airplane today. The 747-8 Intercontinental and 747-8 Freighter incorporate the GEnx engine—one of the cleanest, quietest, and most fuel-efficient turbofan engines in the world. It is based on the 787 Dreamliner engine, but optimized for the 747-8.
