Bruce, There are many inconsistencies in your own statements above.
Where does the 200 MPH come from? Where is actual evidence that the airliner was flying a ziz-zag pattern? Where are you suggesting that Cooper jumped? Etc., etc., etc..
The story of the so-called "FBI Map" apparently originated when Carr posted it to DZ and asked if anyone knew where it came from? Himmelsback reportedly stated that he had never seen that map. So the history of that map is uncertain.
It is certain that none of the flight paths and times shown on the "FBI Map" are believable. I wrote a number of posts about that in 2009 and they may still be on Sluggo's web page.
I do not know of anyone, except yourself, who claims that the FBI did a cover up on Cooper. If they wanted to cover up the flight path and Cooper's probable jump area, then the "FBI Map" is not the way to go.
A better way would be to simply delete all information from the radio transcripts that would show the flight path and the times at various points. Then no one could determine where the aircraft was at a given time. Oddly enough, that appears to have happened. Have I just contradicted myself?
Speaking of wine, Robert, I think it's time for some. ahhhh...
Flight paths, cover-ups, Cabernet...all in a day's work, I say.
Yes, Robert, I may be the only one to suggest a cover-up in Norjak, but how would you describe the FBI's investigation? Incomplete? Compromised? Typical of a large governmental bureaucracy? I'm not arguing with you, just asking.
I find it helpful to adopt a perspective to help shape my research/investigation. It helps frame my questions and approach to the players. Generally in Norjak, I'm thinking cover-up, but I also know that embracing such a view can be a trap, blinding me to other truths and possibilities. Hence, I endeavor to be circumspect.
As a result, in my book I specifically say that I don't know if a cover-up is in play in Norjak. I only use the word "compromised."
But, I do
savor the opportunity to call a spade a spade when I'm among friends.
