If I may, Mr. Chair, I just want to highlight the fact that given the binational nature of the NORAD command, we're going to go for the best toolset that is available at the time but that is also currently available. In these conditions, given the changing environmental conditions and the desire to actually take it down as soon as possible, the asset that was on hand was the F-22.
I must also say that the best tool is not only the fighter; it's also the type of missile. Every condition, based on a radar cross-section infrared signature, may require a different toolset. That's what we've seen in the difference between the high-altitude surveillance balloon and the follow-on three objects that we observed. Those were changing conditions that could probably have required different toolsets.
