 We were in Cheyenne Mountain and we actually heard one or two events that were occurring and we heard initially That there was a small aviation airplane that hit one of the towers in New York City. Hey, this does not look like a General aviation kind of attack and then again we saw in real time the second aircraft hit the second tower And we knew that that it was not just a normal day if you will It wasn't just a normal general aviation episode I think that prior to 9-11 we really focused on that external threat really going back to the roots of NORAD against the Soviet Union and a threat that potentially could be Threatening both the US and Canada externally 9-11 showed us that we also need to be looking at that threat that could come from us could come from us internally At that particular time we only had seven locations that had fighters on the work and The alert capabilities back then we really didn't even fly with live missiles on the aircraft And so we had to make some modifications to our Standard tactics techniques and procedures and we were doing that as we went along So on day one the first thing that we started to do is trying to get access to as many Fighter in command and control and tanker aircraft that we could to be able to flood the skies with a counter capability In case there was additional attacks that were forthcoming Operation no we go is our air sovereignty mission within NORAD This really came out in 9-11. In fact US Northcom was born out of 9-11 That US Geographic combatant command called US Northcom was a direct result of the attack and the need to have a single commander That was responsible for home and defense
