Doesnt explain the ENTIRE building collapsing in its own footprint even if its true that it burned hot enough to weaken in certain areas.
Many lesser built steel bldg have faced worse without collasping https://911research.wtc7.net/wtc/analysis/compare/fires.html
Catastrophic collapse means that the vertical load bearing capability has gone to less than the burdened weight (all the structural margin has been used up by the fire-weakening of the columns). The way this happens is that first one column fails. The compressive load is then redistributed among the remaining columns at the speed of sound in the hot steel (probably close to 4000 feet/second). With one column gone, the load per column just got greater, and another column will fail. This is a chain reaction that will take only milliseconds to spread across all the columns, during which time the overburden would scarcely have moved. The underlying floor will have failed, the overburden falls at gravity acceleration, lands on the next floor, and the process starts all over again. Since the upper stories are massive, there is plenty of inertia to prevent it from tipping in the time it takes for the downward collapse.
I doubt other buildings have had occasion to collapse in just this way, which is the result of the structural core being rendered useless by heat-weakening from a tremendous fire.
NAH,that is just NIST coverup nonsense
These people who risked their reputations and livilihoods to tell the truth are FAR more credible to me.

Are these the types who tout the idea that the building was taken down by "thermite explosions"? I think there is a reason why their voice is in the minority on this event. From what I have seen of them, they walked in with their own preconceptions and simply sought what they hoped to find. I find that most people don't understand the concept of inertial confinement, but it is a key to understanding how it happened.
Are you competent to evaluate their analysis? Or are you just reflexively taking the view that, if they are contrary to "the government," they must have their finger on the truth? After all, the government was correct about us going to the Moon...
MOON gimme a break.
I know you are just here to back Govt and MSM narratives but for those looking for truth about the fake Apollo and NASA stuff suggest visiting Aulis.com to start.
