Well your statement is not supported by the fact look at how fast NORAD noticed the two plane were not were they were suppost to be.

NORAD, by their own account, held on to this most vital information of these two hijacking for at least 6 minutes before ordering Otis to scramble . NORAD may have held on to the vital information of American Airlines Flight 11 for perhaps 8 minutes, maybe 10 minutes (see 8:36 a.m. # 25 statement by NORAD spokesman, Major Mike Snyder), possibly up to 26 minutes (see 8:20 a.m. # 14 American Airlines Flight 11 transponder signal stopped transmitting its IFF beacon signal) and let us not forget that the last transmission of American Airlines Flight 11 with Boston air traffic control occurred at 8:13:31, so maybe NORAD had over 32 minutes before they notified Otis to scramble their two F-15’s.
So I don;t believe your BS for on minute. it did not take hours. They noticed and the flights were in the wrong place and the Higher Officers were to confused by the training exercises to react. On a normal day the planes once they turned off their communication devices. Jets would be scrambled and the flight forced down with three fighter jet one on each side and one on top. If the jet started to descend it would be shot down.
8:46 a.m.: NORAD orders the 102nd Fighter Wing of the Otis Air National Guard Base in Falmouth, Massachusetts to scramble two of their F-15 fighters. This is from the 102nd Fighter Wing's mission statement of September 11, 2001. "Our aircraft and their crews are on continuous 24-hour, 365-day alert to guard our skies. The 102nd Fighter Wing's area of responsibility includes over 500,000 square miles, 90 million people, and the major industrial centers of Boston, New York, Philadelphia, and Washington, D.C."
