Two senators say the Air Force should move forward with plan to buy aerial tankers even if Boeing is the only bidder. Orrin Hatch, R-Utah, and Kent Conrad, D-S.D., said in a joint statement that there have already been too many delays. Northrop, which wants to assemble the planes in Mobile, Ala., said Tuesday it would not bid on the contract unless the Pentagon makes big changes to its request for proposals.
