A Henry62 dev'esser sfuggito sicuramente questo particolare:

Niels Harrit: The two last options I can definitely rule out. It could not have come from the airplanes. If it had been there beforehand – those who put it there, I urge them to step forward and tell us how and why it got there. One thing, which has been mentioned frequently in the discussion following our publication, is that this could be the primer paint which was applied to the steel beams in order to prevent corrosion. And many of the ingredients are the same. In terms of the iron oxide, as I told you, which is red in color, you see it hugely on steel beams when they are protected, it’s iron oxide… So, some of the chemicals in there are the same. But the composition of the primer paint used… there are two very good reasons for it not being paint, in my opinion. One is that the composition, chemical composition of the paint, primer paint, used in the World Trade Center, according to NIST (the National Institute of Standards and Technology) is vastly different from that what we are seeing. To be specific, I’d say that we are missing large amounts of chromium, zinc, and magnesium. Next, which can be understood by everyone, is that the paint applied on the steel beams is stable to elevated temperatures. NIST did experiments with the steel beams, because they wanted to use the appearance of the paint as a measure for the temperature the steel beams had been exposed to. And let me be specific. When you heat this steel beam up 250 degrees Centigrade, it starts cracking. This is because the steel expands more than the paint. They get what they call mat cracks. And it keeps on cracking until the temperature is above 650 degrees, where it starts peeling off, forming scales. This continues to about 800 degrees, when this scaling becomes excessive. But it does not burn. So, the paint on the steel beams is stable beyond 800 degrees Centigrade. Now, the stuff we have found ignites at 430 degrees Centigrade. So, it is not the primer paint. So, what I can say is… Is this nano-thermite? Well, it quacks like a duck, it waggles like a duck, it looks like a duck, maybe it’s a duck? This is all we can say.NIST did experiments with the steel beams, because they wanted to use the appearance of the paint as a measure for the temperature the steel beams had been exposed to.
