Look at the videos of the buildings in mid-collapse. The outside aluminum sheathing and beams are being thrown hundreds of feet almost straight
outwards with tremendous force.
It was steel.
Also, if you'll notice, only sections of it are being thrown out - all of them being the vertical supports (with a few horizontal pieces occasionally
This is consistent with failure of joists under excessive torsion of the vertical supports.
The concrete floor is being molecularly disintegrated, it's water content boiling instantaneously, an amount of energy not available either
kinetically or from the fire high above.
Oh my.... I'm sorry, I didn't realize how new most of this was to you.
Concrete doesn't have much water in it. The curing process for concrete involves the evaporation of water.
See my previous post for the explanation of your powderized concrete.
The massive steel core is that black smoke rising upwards, that's a mushroom cloud although not the kind we expect to see.
A mushroom cloud is generated any time hot air rises rapidly. As the air begins to cool, the still super-heated air below it continues to force its
way upwards, causing the cooler air (and the debris it contains) to slide and 'drop' away.
The steel core ended up scattered at the base of the collapse (most of the building was empty air). The black smoke was vast amounts of unburned
polycarbonates. You see that a lot in building fires.
Get it through your heads people. New York City was nuked.
I've watched the 9/11 conspiracies since a couple weeks after the event. I've seen the evolution of the argument.
At first - almost everyone was onboard with the idea that there was something amiss about the aircraft that crashed into the towers. "extra fuel
tanks!" they argued.
Then we had issues with the Pentagon: "human pilots could not have possibly made the maneuver that brought the plane into the pentagon!" - with a
side argument of "It was a missile that hit the pentagon!"
Then we got to the controlled demolition argument and its many variants - which has lost a lot of ground in the collapse of the towers and, instead,
become popular to explain WTC7 (because WTC7 just -had- to be demolished to anger America enough for the conspiracy to work).
After a lot of the conspiracies were subjected to scrutiny and none of them really survived the debates intact (most of the time the conspiracy crowd
would fragment into a hundred different exclusive arguments) - we started seeing some of the more "creative" explanations.
One of them, I # you not, involves an orbital particle cannon (The "GDI Ion Cannon - as I like to call it).
The 'why' is another issue, but it obviously has a lot to do with demonizing Iraq and Muslims (since several of the alleged hijackers were
Saudis, why did we not invade or bomb Saudi Arabia???)
Except 9/11 had nothing to do with Iraq.
The planning and orchestration of the attack was done by 'AQ' - largely funded and centralized in Taliban-controlled Afghanistan.
Which is where we struck.
Iraq, admittedly, was a "oh, and while we're here..." Though the port and aircraft infrastructure in Iraq has been very useful in operations in
this entire theater. I can't help but feel the decision to strike at Iraq was as much of a logistics issue as it was to remove a known developer of
chemical and biological weapons (that we did not want to end up in the hands of AQ - and there really is no telling what people in various countries
will do for money that AQ has plenty of).
Or, maybe use your BBQ for an example. Build a fire in the thing, add some kerosene, let it burn for all of 57 minutes (the time it took for
the second building to be hit to fall) and watch the legs of the BBQ collapse into themselves in a pile of smoking dust and U-shaped beams.
You... really don't understand the concept of a model, do you?
How about, in the barbeque pit, placing a 50lb weight suspended one foot above the grill by a few steel beams no thicker than what comprises aluminum
That's to simulate the upper sections of the floor supported by steel struts that were exposed to the fire. When the steel weakens, it will sag in
some locations until, finally, one support's integrity drops too low and causes the burden on the other supports to shift abruptly and above their
failing points - triggering a rapid and complete collapse of the support system.
Then your 50lb weight slams into your barbeque pit.
I swear... this is what happens when kids grow up doing nothing but playing video games.
