Wtc Core Design, How were they built Options

"WTC core design"

You could sure have fun reading all these pages.

But start at Sub level 5

So they found iron micro spheres in 4 dust samples. That means high heat events and explosive disbursement.

Did all 4 samples have the same ratio of iron micro spheres to the total mass of the sample?

If so do we assume all dust was uniform and can compute the amount of iron that was disbursed... ir was inside the structures when the were destroyed?

If so, how would the dust be so uniform?

If it wasn't uniform how can we conclude how much iron was in the structures or explosives in the case of the red gray chips?

It appears that in all three towers the high energy high heat events were localized ... somewhat. That is... most of the structures were destroyed by gravitational collapse... after parts of the supporting structures were removed. That would seem to indicate that the dust would have different characteristics depending on what it was created from...

What does the dust tell us?

Why didn't the paper burn?

Any thoughts?

I was intrigued to learn that the samples had the highest concentrations of metals ever found on the planet. I was particularly interested in the high amounts of iron and chromium. The reason for my interest was my knowledge of the concrete rectangular core structure and the rebar which was very special and strong having high amounts of chromium. High tensile steel.

This photo shows the only full length box columns of the towers. The north side inner framed wall of the exterior steel structure that was fastened to the concrete core walls. The sloping/curved top edge of the concrete can be seen behind the interior box columns, silhouetting the columns.

Then this image of WTC 2 at a very different phase of particulate emission. I suspect that the very dark particulate clouds over the south wall, the narrow end of the WTC 2 core are the steel from cutting charges detonating at 300 ms intervals, which equals free fall in 40 foot pieces.

Conforming to that hypothesis, are faint vertical striations in the dark particulate as if the particulate were being ejected at high speed from separate tubular ducts. The south interior box columns, outside the concrete core with their wide axis perpindicular to the cores long axis.

Perhaps filing cabinets were shredded by shrapnel comprised of hard stone aggregate and in the process some large bundles of paper made it mostly intact to the window exits.

BTW I have a copy of an extensive dust analysis that was around some years ago if anyone is interested. Here is a list of authors/sources of it.
