Flight 77 data recorder

How come i don't see this being used at all in the "911 conspiracy" debate around here?

Calum Douglas' report after his FOI request was finally granted is 9 months of astonishing research. Proving once and for all the flight path and trajectory of flight 77.

I would be interested in refuting this. Hopefully, someone on the "official story" side can watch this 55 minutes presentation. All information discussed in this presentation are facts derived from the flight data recorder of flight 77.

 

good luck on any REAL refutation
