Well, yes, there was a lot of confusion that day and the FAA and air traffic controlers were at its epicenter in many ways. No suprise that they made some mistakes, is there?
I agree with the others, it looks like Jay Rockefeller, Dale Carnegie, and Sung Young Moon, or whoever, got together and laid out the perfect plot...and we have DISCOVERED it.
Understanding the events of that day through ATC would have been a real-time task that was understandably....misunderstood. The only people who had even an inkling were the souls trapped on those aircraft. Even then it would have been unimaginable.
