I'm not sure what the plan B notion is for us. We have a commitment to a program, like we do for any other programs. Whether it's the C-17 or C-130, we're proceeding with that program with due diligence, as fast as we can. We will make the right decisions. It's the most effective way of doing a transition to a new fighter fleet.
Our F-18s remain viable. That's why we've invested a lot of money to make sure they remain viable as a combat platform to the end of the decade. At some point they will need to be replaced.
