Almost all of the concrete in the twin towers was turned to a fine dust and ejected from the buildings at high speed in all directions creating the huge dust clouds we all saw on 9/11. Very little intact concrete made it to ground.
When the building was constructed the concrete was poured into a floor pan, essentially a corrugated steel sheet, then covered with carpet or other flooring material. The official explanation for the collapse of the buildings is that one floor fell on the floor below it, and so-on down the tower. If this 'pancake' theory of collapse were correct we would expect to find the concrete floor slabs to be stacked on top of one another at the base of the towers, instead essentially all of the concrete in the twin towers, was converted to a very fine dust which was ejected at high speed horizontally from the tower even from floors near the very top of the tower. How is this possible? Without the use of explosives how did the concrete get converted to a powder and get airborne? What is the mechanism?
Blast wave, is the only possible explanation. Who cares precisely the how and the what. There was a blast wave, a demolition wave, and therefore, the buildings were intentionally imploded, or in this case, exploded, the first top down explosive demolition of a high rise steel building, with the explanation everyone is supposed to believe, that they simply "collapsed". They were quite obviously taken down on purpose, and the plane strikes and fires were not the actual cause, only the broad daylight "slight of hand" ruse, to create a suspension of disbelief as to the cause of their total destruciton, in the horrified minds-eye of the observing world. That's all that matters. That it was a ruse, the official story about it, a flat out lie. Does it matter the precise mechanism and explanation other than THEY BLEW THEM UP? I don't think so. We've done our job. The sceptics and debunkers, they would like to drag it in that direction, with questions like - when did they wire the buildings for demolition? How many bombs were there? Was it on every floor, or every tenth floor? (said with a shrill wine)
Well, even if every tenth floor, with zero resistence, given the laws of motion, it would still have taken over 30 seconds.
The only possible way they could have come down that fast, is by a blast wave, removing all structural integrity BENEATH the falling debris plume/fountain of building material. Period. That's the only thing that needs to be proven unequivocally and has been proven, and it does not matter where those graphs came from, as they depict the truth and the reality in a very easy to understand, straightforward manner.

A great point and something I have pointed out to people on numerous occasions with the exact phrase "top down" which for the most part I agree with.
What is also apparent though is the very top floors above impact were "bottom up" - just like a normal controlled demolition - almost as if the top 30 stories were treated as a seperate building. After the top 30 floors was demolished bottom up, the top down progression starts from there after.
Photos from a static mounted (see guy wire in lower left-hand corner) WTC1 video show the North Tower antenna which weighed 353 tons and was supported by the entire core structure fell first about 10-15 feet and fell 56 feet before the 94th floor began to fall. The large exterior sections were shattered and blown out of the building in the original What we saw - Bob and Bri video at about the 19:42 time and the core shattered which is why the antenna fell first in other WTC 1 videos. Or more likely, perhaps the core columns were also shattered in the sub-basement levels prior to the explosions blowing the large pieces out in the above video, dropping the antenna first.

Good post, thanks! I think everybody on the planet knows it was an internal job these days though, but you will always have a few people around the place who fail to understand simple math.
