I am sure you would not be concerned about Boeing and their proposal costs if they lost. And by the way, apparently you are not aware that Northrop Grumman did NOT bid. They withdrew from EADS.
Apparently you are unaware that Northrop Grumman was the prime on the first bid.
This thread is about this bid and your comment about NG, absent any reference to previous bid, makes it clear you were unaware of who the bidders were during this bid. Unless, of course, you were not clear about your post.
