Right, which some people have termed sunk costs; but yes, yours is much more correct.
With respect to the F-35 program being a development program, going back to the F-18, there were far fewer F-18s flying at the time when we made the decision to buy that airplane than there are F-35s flying now. So I would suggest, maybe to Mr. Ross, that, yes, it's a development program, but we've been there with development programs before, which turned out just fine, thank you, meaning the F-18. Is that a fair statement?
