The commercial version of this jet carries 100 passengers, but in the executive model, just 19 seats share the cabin. Five zones in the jet can hold hundreds of different configurations of dozens of modules; options include a bar, a lounge, an office, and a bedroom. Globe-hopping range means nonstop legs from New York to Moscow or London to Dubai. Radiant heat from the cabin floors, wool carpets, extra soundproofing, ample baggage compartments, a spacious galley, an optional shower, and a color palette with hundreds of choices add to the comfort level. Fly-by-wire controls help ensure a smooth and efficient flight. Deliveries began in early 2009.
