Boeing said late Friday that it may protest the U.S Air Forces decision to chose air tankers made by rival companies to replace its own aging fleet.

Boeing's comments come after meeting with Air Force officials Friday for a debriefing on why the company didn't win the multibillion dollar contract.

While we are grateful for the timely debriefing, we left the room with significant concerns about the process in several areas, including program requirements related to capabilities, cost and risk; evaluation of the bids and the ultimate decision, said Mark McGraw, Boeing's KC-767 tanker program manager.

McGraw also said reports that Northrop-EADS won by a wide margin could not be more inaccurate. The company will give serious consideration to filing a protest with a decision next week, McGraw said.
