Who Controlled the Planes?

The following attempts to address some of the questions surrounding the peculiar behaviour of the flights blamed for the calamity that was September 11, 2001. For example – why were all the flights well into their flight plan and required to turn around and their transponders turned off(suspiciously only at a point where ‘radar gaps’ existed, clearly not public knowledge)? How would the ‘terrorists’ have knowledge that even the flight controllers didn’t have? Why didn’t the 9/11 Commission even question this peculiar flight plan? How is it that the three planes in question changed their route and turned off their transponders within seconds of eachother? And why the big cover up regarding the airliner hijacking exercises perpetrated by the US military in the months leading up to 9/11 (some of these involving the world trade center)? See for yourself!
