Repeating this numerous times doesn't make it true. Footnotes 149-151 all deal with the missing Flight 11, and they all contain the exact channel and time. Moreover, the following quote:
Mission Crew Commander, NEADS: Okay, uh, American Airlines is still airborne. Eleven, the first guy, he's heading towards Washington. Okay? I think we need to scramble Langley right now. And I'm gonna take the fighters from Otis, try to chase this guy down if I can find him.
is footnoted as 149. And it gives the name of the Mission Crew Commander at NEADS who said it: Kevin Nasypany.
That is quite verifiable.
