No towers with the proportions of the Twin Towers have steel cores.
That's because there are no towers with the proportions of the Twin Towers.

And? What of it? You have produced a building that has a concrete core, that everyone knows has a concrete core, that is advertised to have a concrete core. And this proves....what?

Christophera said:I’ve argued this fact of the Twin towers concrete core on every board that has a 9-11 forum, and always, there is a die hard group that works together to try and make sure the concept is smeared and ridiculed into oblivion.

It isn't clear that there is a wall there. The color in between what you are calling the end of the wall and what your are calling hallways is the about the same as the color of the debris cloud to the outside of this area. And where is the top of the wall? There is no clear vertical boundary.
And even if it is a wall, it is no thicker than your "interior box column". This would make it about 2-3 feet wide, right?
Concrete cores have proved themselves through the Twin Towers as being the best for very tall narrow towers.
Actually, all this shows is that concrete cores have proven themselves as being the best for buildings in the configuration and environment that the Petronas towers are in. The fact that they have concrete cores does not prove that the Twin Towers have concrete cores.
My neighbor's car has a hybrid engine. Does that mean that all cars have hybrid engines? Same argument.
hey guys, notice how christophera conveniently adds to his "memory" of the documentary once things are pointed out to be impossible then when its shown later that its indeed possible but with limitations, he "suddenly" remembers that it was also stated in the documentary?Your history is correct. The documentary mentioned that they had multiple pumps on a number of levels to keep the pressures divided down to managable levels to gain the elevation needed.
High pressure mud pumps were developed by Gardner Denver and a few other companies for pumping drilling mud and they were adapted to concrete.
An engine doesn't have a safety factor and a tower does. Not an appropriate anology.
The info on the pumping system was in the documentary. It was a huge expense and the documentary was all about explaining the costs for the public buildings to the public.

first he states that a pump was built on site, then now he claims each level had pumps....(which is not possible btw).
wow, this "hour" long documentary seems to be getting a lot of information put into it. heck, with commercials interspersed between each section, all of this crap had to be put into 40 minutes of workable footage.
cool, now we can call the company to see if they had such machines back in 1967.
As I said twice earlier, this must have been one hell of a tedious documentary! Core, core, core, 3" rebar on 48" centres, rebar, rebar coating, rebar security, rebar butt welding, core, core concrete pumping schedules, core concrete pumping system, core build schedule, core, core, core. Nothing about the rest of the buildings.
And yet, before 9/11, if you'd asked me what I knew (or THOUGHT I knew) about the Twin Towers, I'd have been able to say only that they were in Manhattan and they had an innovative steel core to maximise internal space.
I'm no architect or expert, but even I remember hearing about the steel core. From what you're saying, it was a lie fostered by whoever (or is that wooever?) to cover up the C-4-laden concrete core - a fact that must NEVER be revealed! A conspiracy requiring top secret clearance even for welders. A conspiracy that has lasted for thirty-five or forty years. A conspiracy that involves the deliberate murder of 3,000 innocent souls.
And yet, when a PBS documentary crew come along, the authorities gleefully tell them all about the concrete core, the top-secret rebar coating, the strange movements of workers, the security requirements both for the stored rebar and the welders . . . semingly nothing else.
The steel core was a FAMOUS aspect of the Twin Towers - even I knew about it. Are you saying that not one architect or structural engineer watched the documentary and furrowed his brow in perplexity? This would have been a major issue!
And yet, ELEVEN YEARS after the documentary was broadcast, they had SUDDENLY to pull the documentary and all records it ever existed?
Why the hell wasn't it stifled at birth? Why did they even give those documentary-makers all that DANGEROUS info? Other documentaries I have seen were given the old "Innovative Steel Core" line, and the makers seemed to swallow it. Whywere these PBS guys treated so differently?
If I may add my contribution to the testicular fest: BOLLOCKS!
The evil guys always tip thier hands so the good guys can catch them. It's in the script.
The first shows what might be interior box columns and an empty core area. The dimensions on center or column dimensions do not look right for the Twin Towers though.
The second shows elevator guide rail support steel and diagonally braced crane platforms inside the line of interior box columns and floor beams.
This image explains the last image, the tower on the right and the light coming through.
The 2 narrow blue lines represent each side of a hall opening and the thick blue lines represent entire openings viewed at a low, obilque angle.
