All I asked was for you to come up with a single other burning building that collapsed in a perfectly symmetrical manner like the three 911 buildings.
Surely you can come up with one, even though the engineers in the second link couldn’t.
Name one that didn’t. Take all the time you need, sparky.
I can respond to your question.
That the collapse happened, you say, in a perfectly symmetrical manner would prove it was not the result of a man-made demolition. The number of times a demolition has gone perfectly as planned is about zero.
Collapsing a building requires weeks if not months of preparation. That includes sawing/cutting important structure points. Testing is usually conducted on sample areas and sample materials. Only after repeated checks is the wiring laid down going back to the detonator switches.
That kind of thing would be noticed, especially by anyone entering or even driving by the building. Matter of fact, traffic would not be allowed near the target building.
SO, I wonder if these engineers would say that a demo team would risk death to run demo wiring, do tests, and be near enough to hit the switches on the detonators ? During a fire. With the building being hit by burning debris which would have a high probability of setting off some of the charges prematurely.
TO sum up, with the conditions at the time and the lack of testing and lack of time to prepare the building properly and lay down wiring for the explosives there is no way that is was the product of a pre-planned demolition.
Burning debris landing on top of a building causing a fire from the top down and the force of gravity are an ideal method of having a collapse be almost perfectly symmetrical.
It’s never done that way because hauling thousands of tons of debris to the top of a skyscraper and setting it on fire, then dropping it on cue is beyond the ability of any demolition team.
