If I can change channel a little bit, I'd like to talk about procurement.
One of the things that I think scare all of us is the sole-source contract. I've always wondered, and sometimes I guess you have no choice, but in a case like the C-17, for instance, how do you compare? How do you know that you've had a fair price? That's always bothered me. Sure, you're limited to Boeing; it's the only company that can supply the product. Do you look back at past sales to other countries? How do you make sure that your country got the best price possible?
