How did the huge steel cores in each building go straight down (at freefall speed) and turn into dust-sized particles if the building just collapsed due to structural failure or melting as some people claim?

To the person who decided to be insulting, it's funny how neither you (nor anyone else) can answer the question. To the girl blabbing about momentum, how does that turn steel to dust? Answer: it's impossible.

i would ask a structural engineer. if the planes (which we all saw fly into the tower(s)) were filled with all that fuel, then they would burn for quite awhile. fuel (with gravity, would fall to the lowest point), when ignited would continue to burn. i'm not sure about the weight of burning upper floors to put pressure on lower floors...but the impact of a mega ton plane hitting the building at such high speeds would make the building unstable therefore easier to fall. i have seen pictures of earthquakes where the foundation is upset due to a fault shift and it falls in on itself. all just a guess but an engineer should help you with your questions to see if this is a possibility. seems like it could very well happen to me. i would spend my time wondering why rubberneckers stop traffic looking at accidents....

Why would it have to be at free-fall speed to turn anything into dust?
I have carpets in my house that are full of dust. All I have to do is shake them, and dust clouds come out. Magnify that by the number of floors, and that every floor has more carpet than 10 of my houses, and the carpet alone would make enough dust to choke you.
Then, consider suspended ceilings that have been collecting detritus for 2 decades....
And, consder that concrete turns to dust when it is impacted with TONS of debris from above....
Do you think they crashed into the buildings with a plane-load of used vacuum cleaner bags?

For what it's worth, the steel was not "turned to dust."
It was present in very large sections as pictured in countless photos of the aftermath.
In fact, much of it had to be cut into several pieces to enable it to be transported out of the city during the cleanup.
The rest is debunked because it is self evident.

Why they came down...? More than likely a combination of the intense fire, weakening of the level supporting structure and something people don't like to hear... poor and experimental building design engineering... all of the tower strenght was in the outer sheeting... once it was compromised the overall strenght of each tower was lost...

Fire on upper floors caused the steel supports to fail. At least one floor fell on another. The supports for that floor could no support the weight of two floors. This compounded itself as more and more floors collapsed.
It is fortunate the building failed in this manner. Just imagine how bad it would have been if it fell to one side.

Um....why it is so strange to think it would happen that way ? Ever heard of momentum ?
