New piece on my blog:
NTSB Animation Internal Geography, Part 5: A Turn For
the Worse
The recent Pilots for 911 Truth AA77 3D Flight Path video is all hypothetical - they ignored the altitude data to put the plane, for argument's sake,
at or near the official altitude to see if descent angles matched up (they don't but that's another story). They also ignored for the moment "as a
variable" something called “NTSB northern plot data,” "transitioning to" the (altered they say) FDR data path of 71.2 degrees magnetic.
Now some of you will be aware that I started
a thread here
a few months back looking at the only north-path "data" I knew of - the NTSB animation that shows a final flight path of 90 degrees magnetic - north
of the Citgo and Navy Annex just like the PentaCon witnesses said.
Most smart people decided the final overlay map of the Pentagon area was simply rotated 20 degrees counter-clockwise, making the FDR path
look
like it went that way. There is no other data supporting this path, which is why the Pilots decided the other data was "altered," and only the
animation showed the true heading.
John Farmer: "My guess is the simulation was done before the data alteration (that is why in the video it flies north of the Citgo station)."

Pilots head Rob Balsamo just confirmed to me the extent of this "northern plot data" and that he still believes:
“the map isnt rotated. We are not sure exactly how the NTSB made their plot as they are refusing to answer any questions. […] The grid on the
ground correspond to lat/long lines in terms of true north and are accurate at the runway and at the pentagon/map in terms of angles/parallels. The
only thing that doesnt correspond is the heading in the heading indicator at end of flight in which John Farmer did a great job locating the
alterations.”
Wrong on all fronts. The 70 reading in the animation dial is almost the only right thing for that time frame, matching the "altered" FDR data and
the damage path before and inside the building. The ground grid is off in both proportions and scale; instead of rectangles of about 5:7 proportion
they are square, about 5.1 by 4.3 minutes each. The orientation of the grid is off, turned about 10 degrees CCW, as if oriented to magnetic north. It
clearly does not line up with real world lat/long lines at Dulles and the Pentagon. (these findings explained
here)
And most importantly, the final overlay map is rotated, and it's via this rotation that the NTSB "plotted" their "data." This is my graphc
explanation. I hope this puts to rest any lingering doubt that the map is indeed rotated.
My ginal analysis of the lines seen in the NTSB animation. Effective rotation - 9 degrees CCW - or magnetic as north minus imprecise graphics.
Approaching overlay map crossed by a "latitude" line, marked.
Map analysis - Note the features identified, the angle
of Navy Annex...
My best guess for overlay map area (turned 90 degrees) - presuming square
The yellow line is offset from real-world lines by about 7 degrees.
Above map re-rotated to match the yellow line back with the grid. 9 degrees plu 7 = 16 degrees counter-clockwise. Original discrepancy: 20 degrees
CCW. This is 80% explained right here, and based on imprecise graphics. Not too bad I'd say.
So, for the record: Other than the map rotated from the rotated grid, which is plain enough to see, there is
NO "northern plot data" to
"transition" from and there never was.
Thank you.
