How did this happen?

I received a call from my wife while at work and our office turned on the over head TV, seeing the first tower in smoke and hearing that a jet plane had crashed in to it, on a clear day with visibility in the miles the first thing that came to my mind is "How the hell did that jet crash into the tower?" Having spent a few years in the United States Air Force and watching B52s, F105s, F4s and other planes take off and land in both good and not so good weather it struck me as strange that this would happen until the second plane hit. Having seen planes scramble during an alert there has not been seen by me any explanation as to what went on in our military and or government between the time the first plane hit and the second. Maybe an answer will never be coming.
