Boeing CRW / X-50? Concept art (Boeing)
CRW - Suspected of being the enigmatic X-50, under development (2002) at Boeing's "Phantom Works" is a high-speed VTOL aircraft as the Canard Rotor/Wing in manned and unmanned versions. Also known as "Dragonfly," CRW will combine the hover efficiency and low-speed flight characteristics of a helicopter with the high-subsonic cruise speed of a fixed-wing aircraft. Powered by a turbofan engine utilizing diverter valves to direct thrust to the rotor blade tips or aft to the jet nozzle, with dual bleed thrust during transition, able to operate at speeds in excess of 460 mph.

According to Jane's, the two prototypes were first designated EC-18C, but this was changed to E-8A. The one new-build aircraft with CF-M56s was an E-8B. Jane's claims the -8B never had electronics installed and was bartered to Omega Air for five used 707-320s in 1993. All the "production" (rebuilt from used 707-320Cs) E-8s are E-8Cs and the two E-8As have been upgraded to the E-8C standard, too. ( David Lednicer)

Estimated cost of development: $8-$10 billion. However, faced with apparent lack of commercial interest, the project was abandoned by Dec 2002 in favor of the slower but fuel-efficient 787 Dreamliner, to which much of its research was applied, including carbon fiber-reinforced plastic for fuselage and wings, and bleedless engines.

Y2 will replace 757 and 767, possibly 777-200it initially referred to the Sonic Cruiser, but has now been built as the 787 and covers the 220- to 320-passenger market. Y3 will replace 777-300 and 747 in the 320+ passenger market.
