Well I've been at for most part of the evening, taking a looong hard look at everything, re reading everything 10 times, looking through tons of graphs and reports and this is going to make a few people happy.
I will have to eat humble pie on this one for the following reasons
1. The animation cannot be traced back to the NTSB and in fact lead back to one source. So authenticity is doubtfull
2. All NTSB FDR data states, including the animation that the last know reading was magnectic heading 70 degrees. Now overlaying that over a sat image showed it was still out of the light pole path, but since maps are true north and magnecting north is around 11 degress off true north, making adjustments for that, it pretty much follows the light pole path. Although magnetic north keeps on shifting so this cannot be considered conclusive unless we know what was magnectic north on sep 11
I digged out as much NTSB data as I could to study. The NTSB site is a huge PITA to navigate and get anything out of. FAA is even worse

The above is the complete NTSB FDR data, as you can see on page four it states there is also a csv file for this as stated on page 4, but I couldn't get it directly off the site without having filling out FOIA requests but i was able to find external sources of this, I got it off a few sites anti and pro for comparison and they seem to be the same, hard to check each and every parameter as it turns out into 31,000 pages worth of PDF. Yes I went through the trouble of converting the csv into pdf, turned into a 117 MB 31,000 page document ! But you can use to the csv in excel aswell. Anyways we still have the NTSB FDR graphs to use as reference and see if they match.
Radar data also exists
https://www.ntsb.gov/Info/Rec_Radar_%20Data_%20Study_all%20_aircraft.pdf
As you can see its in on a CD and will need another FOIA request, haven't look for an external source yet, but will soon.
Here is some more

So in conclusion there is no way to authenticate the animation and even then the animation heading is magnetic heading 70 which is agreement with NTSB FDR data, check the links above and the animation draws an incorrect path
But this does not mean all is hunky dory in the Flight 77 Vs Pentagon camp, just removes the animation from the evidence through a process of elimination.
There are still inaccuracies in the last seconds of data. The altitude is way too high to have clipped the poles. Also the plane traveling at over 500 mph ( way above its max operating speed at low altitude as specified by Boeing ) from around 200 ft, leveled out flying parallel to pentagon lawn as show in the five released frames from the CCTV camera where we see a level smoke trail comming in ) to hit it at ground floor level with in a second. For such a big aircraft it has to be literally inches above the ground if not scrapping it.
And all these miraclous arial maneuvers are attributed to Hani Hanjour who months before was not allowed to rent a single engine propeller Cessna 172 light plane with a maximum cruise speed of 120 knots (around 120 Mph )because he was having difficulty controlling and landing it. Now many will say well he didn't need landing skills as he wasn't planing to land it. I'll get to that in a second.
Hani Hanjour after passing the east side of the pentagon and doing a U turn now has the pentagon in view, this is where he starts doing his victory lap a 330 degree downward spiral ( Why not just dive into the pentagon ? ) and then does a further massive drop in altitude and then seconds before another one with the 757 now inches above ground.
Now that is much more complicated and difficult than trying to land a 757 at full throttle on a aircraft carrier, so now someone who could not land a Cessna 175 properly ( an average landing speed of 70 knots ) can pull it off ? I'm sure all you have traveled by air in a commercial jet, imagine you are approaching the runway and just before you land your pilot starts to do a 330 degree downward spiral and then makes a perfect touch down at full throttle flawlessly ?
Also while looking around for the NTSB FDR data and animation authenticity I came across a new tid bit of information among other things, that the cock pit door was never opened during the flight, it records readings every 4 seconds.
Now the NTSB FDR report does metion this as one of the parameters the FDR records
http://www.ntsb.gov/info/AAL77_fdr.pdf ( posted again for quick reference )
On top of page 13 listed as Port Name : EICAS L/R A1 Parameter assignment : Flight Deck Door.
Now just from the sheer amount of data given, I haven't been able to trace down this single parameter yet.
Will look into it and analyse the data further and report back.
