Frankly, I would have prefered to see the USAF select the Boeing. I still think the Airbus will turn out to be too large to be the primary tanker, particularly one that needs to operate from forward bases. Sooner or later the U.S. will want something more the size of the 767, but by then that airframe will be long out of production. However, I do believe that the USAF has made a sincere effort to evaluate the two entries on their merits and would not like to see a drawn out appeal that would push the in service date back even further.
Of course, if the Europeans were serious about buying the best available aircraft regardless of where it came from they would ditch that flying subsidy program called the A-400M and buy C-17s from Boeing.
