In any other hijacked attempt, or even when planes fly over restriced air planes are sent out to look at them... fighter jets are used because they can see what is going on in the sky... they are fast enough and should have been spaced around the US to intercept any plane.

There were also reports of phone calls from all of the planes to people on land... either to 911, air traffic or family members... Flight 93 passengers have plenty of phone calls 'recorded'... by the way since when have they been able to record phone calls from cell phones, how do they know what they said?? when did they record it?? On the cell phone?? cause they used personal cell phones to call relatives... when did this get recorded?? --- but back to the phone calls having been placed, why were there not a single american fighter jet sent in the air... what if 20 planes were hijacked instead of just 4... why weren't they in the air to stop any more... how did they know 4 was it?? Why were there not planes next to every aircraft that wouldn't land??

BECAUSE BUSH KNEW IT WAS GOING TO HAPPEN... HE WAS THE FIRST ONE TO SEE IT ON TV...

President Bush was promoting the passage of his education plan at Emma E. Booker Elementary School on the morning of September 11th.

Conspiracy theorists have questioned the President's behavior after being told that the nation was under attack.[100] They think it's likely that he would have been taken to safety at once, presuming that he too would be a possible target of a terrorist attack. That he remained in the classroom for another 7-9 minutes is seen as an indication that his security staff was well aware of what was happening, and was therefore not worried.
[edit]

George Bush saw the first plane hit?

George Bush was asked a question by a child at a town hall meeting:

QUESTION: One thing, Mr. President, is that you have no idea how much you've done for this country, and another thing is that how did you feel when you heard about the terrorist attack?

BUSH: Well... (APPLAUSE)

Thank you, Jordan (ph).

Well, Jordan (ph), you're not going to believe what state I was in when I heard about the terrorist attack. I was in Florida. And my chief of staff, Andy Card -- actually I was in a classroom talking about a reading program that works. And I was sitting outside the classroom waiting to go in, and I saw an airplane hit the tower -- the TV was obviously on, and I use to fly myself, and I said, "There's one terrible pilot." And I said, "It must have been a horrible accident."

But I was whisked off there -- I didn't have much time to think about it, and I was sitting in the classroom, and Andy Card, my chief who was sitting over here walked in and said, "A second plane has hit the tower. America's under attack."

Some have pointed out that George Bush could not have seen the first plane hit the tower live on television, as it was a surprise attack and no television station was covering that area when the first plane hit. The videotape of the attack was not presented to the general public until several hours after the attack. This quote has made some suggest that George Bush has access to footage the general public does not, especially about the September 11th attacks.[101], [102]. Others have suggested that the President's statement was, "a lie fabricated to justify his unwillingness to deal with the magnitude of the disaster that had stricken all Americans on September 11, 2001."[10
