I've recently received a reply to my
FOIA request to the NTSB to obtain some more FDR files from other incidents involving the same make and model of FDR as was in AAL77. I received two FDR files which are among the four FDR files which
I have analyzed. I requested nine FDR files in my FOIA request but the NTSB could only find two of them.
Out of the four FDR files which I analyzed, only the AAL77 FDR file has Hamming Code and Page Parity errors. As you may remember, it was those errors that caused the NTSB to not decode the last four seconds of data.
One of my reasons for filing the FOIA request was to attempt to determine whether the sort of problem that occurred with the AAL77 FDR file had potentially affected other NTSB investigations so that I could make them aware of that if it was the case.
The other reason was to attempt to find evidence for or against
John Farmer's speculation that the AAL77 FDR file may have been deliberately modified to cause the errors. My idea was that finding other FDR files with the same type of error would be make the speculation seem less likely to be true and finding many FDR files without that type of error would be make the speculation seem more likely to be true.

After the second impact the crashes had a high probability they were crimes. They were crimes. The FDR is not needed to solve a crime.
If there was an accident where the FDR had errors like 77; and the data was deemed necessary; if the NTSB could not decode the data, and needed the data, they could get someone like you to decode the data.
911 was not an inside job, the data was not changed on purpose, and based on the specification required for FDRs, I am surprised more data was not lost, but understand systems and timing has improved past the requirements specified for FDRs.
In this case the FDR information is exactly what 77 did, and following the data ends up the same place the FDR was found, save an aircraft length and some sliding. I thought 4 seconds were missing due to the way the requirement spelled out data collection, or other reason - I did not need to get the data, I knew 77 impacted the Pentagon on 911, and killed people, I know why, how and when - don't need the FDR. It is funny you decoded it and debunk Balsamo who can't do math to save his life.
Good job decoding the FDR. In this case if the NTSB needed the data to solve an accident, they would have someone decode it. NTSB does not do crime and the last 4 to 5 seconds on the FDR are not needed to solve why 77 crashed, the evidence of a poor pilot taking over in flight is in the FDR, and the FDR confirms the plane, as does DNA, and all the darn parts, and RADAR, etc.
It is interesting to destroy the fantasy points Balsamo makes up with your effort, thanks for the rational destruction of a fraud, using programing. Good job
It would be hard to find an accident which the plane impacts a large mass at 488 knots - the massive impact might be one reason the data was messed up, in addition I see problems if the data was being written at impact, not sure of the timing, but there would be some problems.
I need you to program my blu-ray and DVD players to be better data presenters when data is damaged... When are you starting your FDR company?
