Boeing's KC-46A Pegasus development aircraft made its maiden flight on December 28, six months later than first planned. The aircraft, N461FT (c 41273), took off from Paine Field, Everett, Washington at 09:29 landing 3hrs 32mins later at Boeing Field, Washington. Previously scheduled to fly last June, the maiden flight was delayed, partially due to problems that emerged with the aircraft's wiring bundles. Boeing reported that 5-10% of wiring for redundant (back-up) systems did not meet the separation distance required by USAF regulations. This first prototype is a basic Boeing 767-2C commercial freighter, which incorporates the fuselage of the 767-200ER, wings of the 767-300, stabilisers and flight deck of the 767-400ER, and cockpit displays of the 787 Dreamliner. Addition of the fly-by-wire refuelling boom, military avionics and self-protection systems, plus a remote aerial refuelling operator station, will later bring the aircraft up to full KC-46A configuration.
