Some Fresh 9/11 Research-- "Federal Aviation Administration Failures on 9/11"

 From Shoestring 911:

Federal Aviation Administration Failures on 9/11: Why Did Those Responsible for Responding to the Hijackings Get It So Wrong?

Long but well-research, as usual.

Bottom line is it all supports the idea of hijacking exercises that day impacting the response to the "real hijacked planes", as Shoestring 911 seems to believe.

But if there weren't real planes, do the hijacking exercises mean anything? Were the hijacking exercises used to create the cover story or were they just another layer of distraction?
