the same way first responders do when an emergency is called in to 911
Mr. Deets, you have pushed yourself way beyond the boundaries of your expertise in your mad attempt to claim that no airliner hit the Pentagon.
Since you brought up first responders, I'll point out that I personally ride with firefighters who were at the Pentagon that day, removing parts of airliner and airline passenger - from the very airplane that many, many people directly witnessed strike the Pentagon. Your attempt to wave them away in favor of a supposedly precise assessment of flight path by a handful of unqualified bystanders - some of whom also saw the aircraft impact - is intellectually dishonest.
I've previously pointed out the absurdity of a plot to
fake hitting the Pentagon with an airliner instead of a plot to
actually do so. Your fundmental premise is not only nonsensical, it is actively anti-sensical.
It seems you have considerable aeronautics expertise, if you are the person you're warranted to be, but in pursuit of this pernicious twaddle you style yourself an expert in many other fields (only in several cases to be slapped down by real experts). I am an engineer, and you have committed one of the worst sins an engineer can make: pretending to expertise outside your field.
Worse, you're doing it in the service an insane claim, and making a fool out of yourself in the process. I don't know what happened to you to cause this sad state of affairs, but having worked with many fine and competent people at NASA - technicians, engineers, and astronauts - I am at least relieved you are retired and therefore cannot embarrass the agency with your ravings while still affiliated. I hope you get help, because this path only dishonors you and will bring only frustration and bitterness at time wasted on a delusion.
