I am reposting this until I get some response from the douchebag...
Chris I am going to try again with you....
You seem to operate under the assumption "the cores" were some kind of separate entity from the elevator shafts, stairwells and other framework. Well sorry chris but its just not so.
First the entire structure was designed to maximize open floor space and give as near to equal for all window and elevator/stair access. With this type of open floor plan there really was no "bad" space to rent. There was no area harder to get to stairs or elevators, and there was no area cutoff from a window(s). Making all areas of near or equal rental/lease value.
Also with an open floor plan, there was no pillars or load bearing walls/structures every 30 or so feet as in a traditional similar structure. These things combined to (in the hopes of the designers and port authority) make the building have as much prime real estate as possible and draw in more rentals and create more options and areas to rent.
They designed it so the elevator and stairwells were part of the central core. They were inseparable. The elevators and stairwells framework were part of the core structure. So when you see an elevator shaft guiderail or support structure, or a stairwell guiderail or support structure, you are looking at part of the core. This is undeniable and shown in every single one of your own pics....
You can deny this and try to excuse, confound, or bullshit your way around it, but it is a fact. What you are relying on is a bunch of bad descriptions found in the media over the years, to justify a false hypothesis. Here is a picture I made for you expressly to show what I am talking about. I showed it to you before but you played dumb...
Now as you can see my depiction looks very much like the structure you have been calling the elevator guide/support/ whatever... These were placed at various intervals inside the core structure, and in between these we would get several other beams. These beams would also be interconnected at various intervals all of them together making up what is known as "the core"..
looking at one of your own pics we can see this is most assuredly true and accurate....
See right there? The stairs? yeah its in and part of the "core" structure. And in another of your pics....
Here we see the entire thing just as I described it..... Notice part of the outer walls still in the back ground? And then towards the center of the structure (foreground of pic) we see the "core" with some of the drywall and facade material still attached? This drywall and the facade material was what produced a great deal of the dust you try and attribute to being evidence of concrete... Now imagine all that drywall and material covering the entire core for 110 floors, and then imagine it covering the insides of every outer wall, divider wall, to separate every single separate office from one another. And then add in the fact it separated bathrooms from closets, and everything else that needed covered.
That is where your dust came from chris. it wasn't pulverized concrete for the most part it was drywall dust...
Once again we see my depiction shown all too clearly.... The "core" and the stairs and elevators shafts/supports, are one in the same. They make up the core together. An intricate framework of interconnected pieces of steel all pulling together to collectively make up the "core"...
Now your theory relies on these things being separate... But clearly even by your own pictures they are NOT....
I will be back with more as time permits.....
