Sir, I don't mean to say I'm not the guy to answer that question, but specifically you are asking about how we would do aerospace surveillance. It is a NORAD mission, ongoing today and during the Olympics, to be able to provide aerospace surveillance. A means of doing that is with ground-based tactical control radar. There are other means by which that can be done by airborne-based radar.
I have no doubt, from what I have heard thus far in the concept of operations, that there is not a degree of concern with respect to our ability to be able to establish effective airborne surveillance.
