I have created a new program to decode AAL77's raw FDR file.
I am making it available for download along with it's source code and some output files from the program.
You can read more about it here
It decodes almost 4 more seconds of data than what appears at the end of the NTSB CSV file.
I welcome suggestions for any more parameters you would like decoded or any other features you would like added.
I will also be discussing this on the J.R.E.F. "AA77 FDR Data, Explained" thread as well as here.
mod edit: Although Pilots For 9/11 Truth do not have any reason to believe the above program is offered for any nefarious purpose, we felt the responsibility to add this disclaimer. Pilots For 9/11 Truth do not vouch for nor is responsible for any of the data provided above by Warren. Nor can we guarantee his program is free of malicious code. Download at your own risk.

Thank you very much Warren! He graciously provided an FDR read out limited to the starting and final coordinates all of the recorded flights for the purported AA77 911 plane (before 911 and on 911 all the way to the final position record. This is the link to his 4.6mb file, which contains more than 150,000 lines of positional data apparently recorded every second or so as long as the engines were running.
Following his advice to look for sync lost as the end of a flight and a following 1020 parameter as the start of the next, I extracted each line of data containing those events and 2 or 3 lines that was usually in between the two. That narrowed the lines down to about 150. I gave the very first recorded position serial number 1, then each following sync lost or following 1020 serial numbers 2-48. Number 48 is the last sync lost before the Pentagon, so I gave the three following positions serial numbers 49, 50 and 51. Here is a Word97 file with the extracted data, showing the ones with serial numbers.
Here is a .kmz file plotting those positions along with my serial number, the Subframe Count, and comments showing which ones appear to be the beginning or end of a flight in pink.
1. The first thing that caught my attention was of course the final four readouts, 48 being the final "sync lost" and 49-51 subsequent positions. They show the plane missing the light poles completely. The last position No. 51 is still across the freeway, already past and NE of Citgo, over the second grassy "leaf" of the cloverleaf, slightly past the bridge where the first pole is located. The course is a straight line. Here's a screen shot jpg from the .kmz showing these four points as pink targets.
For whatever it's worth, the final point is practically halfway between the last two RADES positions, which are shown by two dots with line in blue.
This course has the plane going over the south edge of the Citgo. I am not suggesting that this is the course it took - I'm only offering it because it is a good argument to use against the GL's because it is government data showing the plane missing the poles. To show this, I have added some placemarks and lines to the .kmz file that show my thoughts on the approach path of the plane the CIT witnesses saw.
The two green lines are the result of using Hillbilly Calculus to draw a line that evenly distributed on either side the radar returns from the four airports and RADES. Dmole did a more scientific analysis and came up with something close to this as well. This used the processed radar data that Farmer converted into lat/long coordinates.
The red dots with lines and yellow dots with lines are based on the raw radar data from DCA. The first dot is PRange and PDegrees and the second DRange and DDegrees, with the connecting line showing that they are from the same sweep. I think this is to give an average that places the plane between the two dots along the line. This was done rather crudely using the GE compass and ruler starting from the exact location of the DCA radar dish. Farmer thought you had to make a 9.5 degree adjustment to the raw data so the yellow shows it his way. The red shows it done my way without the adjustment.
The red and green show what I think and support the NoC approach and witnesses. Note how the pink INS path runs down the middle of the lot.
I'll post about the plane flights later,. I just wanted to throw this out for comment and critique. I don't think it helps the government and GL's at all!
