Thank you, Mr. Chair, and thank you to the witnesses for coming.
Colonel, I want to just clarify a couple of things. You implied there's a lack of air space monitoring above the north warning system. Are you aware of the space-based capability of air space monitoring through NORAD and other methods that are used to detect incoming unflight-planned aircraft and the fact that we have challenged physically every unflight-planned aircraft that has entered that portion of the air space? It's international air space, but nevertheless we've been out there challenging everyone. Are you aware of those capabilities?
