9/11gate, "AA77" FDR numerology Options

[tumetuestumefais...]

I was looking into the "AA77" FDR record to find out how the Lat/Lon coordinates were shifted by Mr. Stutt and Legge to get the plane on the runway. So I've chosen the map closest to 2001 and I've plotted the last "AA77" landing, taxiing in, standing at the gate, taxiing out and the last takeoff:

(The numbers are numbers of subframes in the FDR and they can also serve as a timing, because their step is one second. So for example when you've frame number 145840 and frame number 145860 it means they're 20 seconds from each other. Only point when it is interrupted is when the plane stands, then the FDR is not recording - in our case at the subframe count 146180. The needed data were provided to me by Mr. Warren Stutt)

Everybody sees at the situation picture that the coordinates taken from the FDR are off.
How much off they are?
I was looking what a reference I can find for landing and I've found the point where the plane sharply turned from the runway to the taxi circuit.

From the logic of the landing, the overal visible shift and the trajectory pattern is absolutely clear where it was:

Then I've got a strange idea and I've decided to measure the distance and angle to the position where the plane quite clearly parked to and departed from the gate:

From the distance number is clear that we keep up with the perps at least numerologically... (IMG:http://pilotsfor911truth.org/forum/style_emoticons/default/rolleyes.gif)

Let's have a break and have a look what number had the gate where the "AA77" was boarded and departed. We easily find it in the Wikipedia:

"The flight boarded through Gate D26, in Midfueld Concourse D at Dulles."

or here:

"In 2001, American Airlines Flight 77, a Boeing 757, left gate D26 at Dulles en route to Los Angeles International Airport, but it was hijacked and deliberately crashed into the Pentagon as part of the September 11 attacks."

Let's yet have look into govt. documents...yep, it is there (page 29):

"Flight 77 pushed back from Dulles Gate D-26 at 8:09 A.M."

Boring. Let's go back to our little petty plots.

Now we need to measure the same distance and the same angle from the point where the plane sharply turned to the taxi circuit:

And where the line ends?

Lets look what number the gate has:

It's not completely clear what a number the gate has - we have there two gates:
9 and 11.

Hmmm... interesting.

Must be a "magnetic declination" error. /sarcasm

What is I think very important is that according to FDR the plane departed from the gate 9/11 at ~12:12:29UTC (FDR timestamp, which we now know it should be quite exact) -not at 8:09EDT as is stated in the official records about "AA77".

I wonder what happened to the passengers who boarded the plane at D26.
There is IAD radar which should see D26 very well. So I think I should look into it around the 8:09 to range around 0.82 and true azimut 148 and find out where the plane taxies and where it takes off and then track it in the 84Rades where it goes -if it is there, because the grounding order was almost 2 hours later, so the plane most probably could very well be already out of range somewhere far west if it was bound to LAX.
A bit problem is I have the IAD data only beginning 8:10, so it could be a bit drag.
As I briefly look into the IAD data I see there unsquawking plane taxiing on the southwards taxi way (range 0.88 DEG 166) as our FDR plane did, but already at 12:10:02.965UTC (when our FDR plane was still at the gate) and later, but I have no means to find out if it really departed from D26.
Maybe Mr. Farmer has earlier data? (IMG:http://pilotsfor911truth.org/forum/style_emoticons/default/dunno.gif)
I need just a minute or two of the earlier data, otherwise it would be quite a guess job.
In 84Rades I indeed see a plane taking off from our runway just before our plane at ~12:16-17UTC which is westbound M3 7020, after flying shortly southwards, it returns northwards and appears to fly westwards in the same corridor as our FDR plane just in front of it and then turns a bit southwards before it disappears from the radar. From the speed and altitude it is most probably a commercial jet.
