The Boeing and U.S. Air Force team successfully completed the first flight of a KC-46A tanker aircraft on September 25, 2015, from Paine Field, Everett, Wash. to Boeing Field, Seattle. This was the first flight of a KC-46A tanker-configured aircraft, following ongoing flights of the program’s first test aircraft, a 767-2C. During the four hour flight, Boeing test pilots performed operational checks on engines, flight controls and environmental systems and took the tanker to a maximum altitude of 35,000 feet prior to landing.
