intersting info. thanks for your work bringing this post forward. I am amazed that the american people ( I am not in USA) have seemingly just bought 9/11 hook line and sinker. It is just seemingly so obvious that it was not just a lot of disgruntled terrorists..

I am a truther myself and don't believe the OS.
However, this report has a fundamental flaw.
That flaw being that it is assumed by the writer
that these aircraft cannot exceed certain limitations
in design when in actuality all kinds of vehicles
including submarines have safe operating limits.
Those who make excuse for the govt story love to claim, "The aircraft was only at this speed for a few seconds and then crashed. It can sustain this speed for a few seconds you idiot!"
Of course they offer zero proof for their claim. Not to mention the fact they are wrong.
I cut some scenes from "9/11: World Trade Center Attack" due to the fact it was technical enough. I have calculated the speeds based on radar data for the last minute, a full 60 seconds.
The average speed over this straight line path is 501 knots. The average speed over the last 2 radar sweeps (24 seconds) is 509 knots. Remember, this is groundspeed. True airspeed will be a few knots higher due to a turn into a headwind. This is also straight line distance measurement over time. Actual speed will also be a few knots higher as the path is curved (the aircraft was changing direction), covering more distance (again, I don't want to get too technical when the simple measurements will serve its purpose. K.I.S.S.)
During this time, the aircraft is changing direction and pulling out of a dive, ie. Pulling G loads.
As pointed out in the presentation, please familiarize yourself with a Vg diagram.
Here is a basic Vg diagram.
Now, the above diagram is for a primary aircraft used to instruct student pilots. But it gives you a good idea of what to think about when an aircraft exceeds its design limits.
It is not so much "duration" as it is a hard limit of combined stress on the airframe, speed and maneuvering.
As stated many times, we have been pressuring Boeing to release Wind Tunnel data (which would include the above Vg diagram for a specific aircraft). We hit brick walls.
Now, I just noticed this diagram pop up on the web the other day when I did a search (it wasn't available when I made the film). It is a Vg diagram for the P-51 Mustang.
Notice the structural failure shaded area occurs in the P-51 at roughly 505 mph/438 knots.
Notice the "Limit Dive Speed" in the above diagram. The "Limit Dive Speed" (Vd) for the 767 is 420 knots. 425 KEAS is when Egypt Air 990 broke apart in flight.
The govt expects us to believe a 767 with its bulky airframe can pull G loads and maneuver to stike a target with a 25 foot margin for error each side of wing tip -- almost 80 knots faster than the structural failure limit of a slick P-51 airframe?
I dont think so.
That is why you see so many experts speaking out.

The list grows.

No one has claimed these aircraft cannot exceed their Max operating, but 150 knots over Max operating? This number is without a doubt, excessive.

Do you feel they label it "Maximum: because anything above such a limit is NOT excessive and considered safe?

I'm not sure they were that worried about safety

Anything over a Max LIMIT set by the manufacturer is considered excessive. That is why they label it "Maximum".

Whether it be airspeed, tire speed, oil pressure, oil temp, any type of limit, if you "exceed" it's max limit, it is considered excessive.

So you agree they are excessive. Good for you. You have taken the first step out of denial.

I did click on the article, there is nothing there but more "opinions". Sorry, this is empty. Your use of the word excessive means nothing to me or anyone else. Here - I am officially saying that it was not excessive. End of story.
