I'm sorry B25 but, ALL the buildings were "controlled demolishing", including WTC7, EXCEPT for the Twin Towers, and your video proves it despite what the voice says. When "controlled demolishing" takes place, the buildings collapse from ground up. When it's not "controlled demolishing" like the Twin Towers, the buildings collapse from top to bottom, unless you want us to believe that every floor on the Twin Towers were rigged with explosives to go off in a timely fashion from top to bottom at the speed (almost) of gravity!
You are only partially correct about the twin towers 1 & 2 ! Look at the videos of the collapse........ the
TOP sections i.e. that above the point of impact in both towers,
COLLAPSED FROM THE BOTTOM UP, the rest of the structure collapsed
FROM THE TOP DOWN, section by section ......... in a very controlled manner.
There is a sound reason for that if you apply the laws of physics. To collapse from the bottom a structure that had a unpredictable asymmetric load would simply topple because the load on one side was greater than on other sides ......... the tower would tilt toward the path of least resistance directly you removed the bottom of the structure, (
The Laws of Motion – Newton), small sections had had to be removed in sections, to keep the descent motion as near vertical as possible.
Did you watch the video that followed the one you linked? The explanation is there!
There was no section of the vertical column steel work recovered from the debris that was more than 11m long ..... which just happens to be the vertical distance between two floors. Look at the people hanging out of the building in the video, the windows were open/smashed and you notice a white vapour/smoke coming from EVERY OTHER FLOOR! That was not jet fuel or furniture burning ..... that was very likely smoke from cutting agents melting steel!
You get clouds of white smoke from cutting agents such as Thermite/Thermate which would take several seconds to cut through the steel of the vertical columns, thus weakening them at specific intervals. The cuts are made at an angle to ensure the column moves inwards or outwards and this is visible in some pictures taken of the rubble at the base after the collapse. A fairly clean cut at an angle of about 20 deg.
I am not going to waste time going any further ....... but there is a logical explanation for the events! Not a conspiracy ...... but a previous commercial/H&S decision taken after the 1993 attempt. I am happy to explain this in more detail if you wish ...... and it all makes sense!
