Yes, it is true that for a seconds or two, the damaged part of the building collapsed bottom up until the rest of the topside of the building collapsed onto the base of the damaged building, which then the whole building came down top to bottom one floor at a time.
After the top section dropped It did not come down one floor at a time, it fell at freefall acceleration. You see that on the videos and for that to happen there must have been no opposing resistance to gravity.(
Newton) If you believe the floors destroyed these columns then there would have been a reduction in acceleration every time a floor pancaked But that was not what the videos all show.
There has to be another explanation?
IMO: The columns started to collapse around the time the top section started its ‘
bottom up’ collapsed. (
or even before?) The floors were outside the perimeter of the central core but descending columns would have pulled the floor pans on each floor in and down with them, and they in turn would have pulled the outer shell in and down as well. I think It was the descending core columns that took out the floors, not the other way round!
That is what happened for both the building, just at different time, but each building had the same pattern in collapsing because the conditions and cause were almost identical.
But what was the cause and what were those conditions?
Again
just IMO, had there been no human interference after the impact, the towers would never have collapsed! The fires would have run out of fuel and then would have died out naturally! If the columns had been weakened then a collapse would have followed the line of least resistance to gravity ..... it would have toppled? It didn’t ..... it defied Newton and went virtually straight down with no resistance. Try explaining how that could happen without some ‘intervention’? It's impossible.
Now, I also agree with you that the core of the building should have stood on it’s own after the rest of the building collapsed around it given the amount of steel and concrete was used to make it, but it did not.
Again
just IMO, I believe it would not have collapse at all ..... it needed help! The floors were light concrete and that stuff cracks (
I have seen it happen first hand but on a smaller scale) and breaks up when stressed. It then forms an immensely dusty rubble. But that is ALL outside the core! If the floors detached from the core columns the whole tower would have conceivable ‘
peeled’ like a banana!
In order for the whole core to be destroyed by other causes (deliberately), then each floor had to be destroyed this way since the buildings came down from top to bottom.
When the columns were removed from the site not one column was found longer than 36ft ..... the height of a spandrel or two floors! If the columns were destroyed almost simultaneously every second floor and fell they would take the floors and the spandrels down with them. You would then get the free fall acceleration we saw in the videos.
Had the building collapsed bottom up just like WTC 7, then conspiracy would have a better acceptance. With such conspiracies, then both the building should have collapsed immediately after being struck by the planes in a chain reaction, regardless whether the buildings came down top to bottom, bottom to up or just sideways.
I agree with you but ..... if it was a controlled demolition, maybe it was a case of delaying that scenario to allow time to get people out? I have never believed that even if they were rigged, that the intention was to kill people, but a ‘
hidden’ means to bring the buildings down into a smaller area in an emergency situation by keeping it to a vertical collapse by controlled demolition, rather than just let it collapse randomly or topple!
However, it did not happen that way, but in the exact same way for both the buildings 1 & 2 as seen in the videos. Unless of course, that the videos has been doctored!
I don’t think any videos have been doctored but did you study this one that I posted earlier?
https://www.youtube.com/watch?v=yaydhlOVogk...... at 1:16 there is a judder on the camera, another at 1:20 and the collapse starts around 1:29. As I said in the original post, there is another video from another camera, which shows the same camera shake. Surely that was indicative of a large explosion deep within the structure .... maybe in the basement? At the exact time of the first shake the volume of the smoke erupts and engulfs the upper structure. I have never seen that explained! But a geological observatory some miles away recorded it as ‘
an explosion’!
