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.

I see Mackey has written a long convoluted post based on the fact he claims "there is noting to debate".
Is it any wonder Mackey does not include a link to "Compressibility" in his post?
Some choice quotes under "Compressibility" with respect to aerodynamics...
Some of the minor effects include changes to the airflow that lead to problems in control
Finally, another common problem that fits into this category is flutter. At some speeds the airflow over the control surfaces will become turbulent, and the controls will start to flutter. If the speed of the fluttering is close to a harmonic of the control's movement, the resonance could break the control off completely.
These are some of the BASIC reasons Mackey writes long convoluted posts when he also claims "there is nothing to debate". I won't bother to get into "Super-Critical" definitions which Mackey obviously lacks basic understanding.
"I don't know enough about the aircraft or the precise flow to guess whether it would go up or down" - Ryan Mackey, Self Proclaimed NASA Scientist.
We do, this is why Ryan refuses to debate this topic with an actual opponent.
Ryan, when will you learn less is more? (IMG:http://pilotsfor911truth.org/forum/style_emoticons/default/wink.gif)
Edit to add:
Mackey added an edit to his post...
If you've ever been to an airshow and seen high performance aircraft maneuvering steeply, you've probably seen this -- and it happens at subsonic speeds.
What's happening is that, under maneuver, the airflow is briefly accelerated to sonic speed, and a weak shock forms, attached to the wings. The air gets compressed and heats up in the shock, losing a bit of heat to the boundary layer and so on. But the airfoil isn't done yet. It next decompresses the air, and so doing also reduces the temperature, since there's no heat entering or leaving the fluid. If it decompresses the air enough, this causes water to condense, forming the cloud.
This is known as an aerodynamic contrail at an "airshow"... (again, just a quick search i did, but you can also see the same on any airliner on landing in high humidity)
What is happening is that the pressure above the wing reduces so low (which is a direct relationship to temp, thereby decreasing temp), that it is reduced to the dew point and aerodynamic contrails are visible. It has nothing to do with sonic, transonic or other type of mach speeds. Mackey is blowing smoke up your ass as usual.
(the best i could find for an aircraft landing... for now... and hey, it looks like its a 757! (IMG:http://pilotsfor911truth.org/forum/style_emoticons/default/smile.gif) )
According to Mackey, the airflow on the above aircraft, above the wing, is "sonic".... lol... Mackey is so lost its not even funny... Its clear why he will never debate a real expert on this topic. I'm really wondering if he really is an engineer at NASA. If he does work at JPL, perhaps he sweeps floors? He does have a little knowledge that one would have in passing by a conversation, but clearly the guy is lost.
