Reply #102: Not so from my view...

Why weren't the rest of the materials...present during the collapse also reduced to micron sized particles?

Why just the carpet?

Seems to me that you were implying that I was saying that only the carpeting was reduced micron sized particles. As to the picutres in your post, they show mostly perimeter columns and other assorted pieces of metal which are much stronger than carpeting.

The perimeter columns were also farther away from the explosives used to pulverize the concrete floors, which would also reduce the amount of damage that they sustained.

But hey, don't take my word for it, here are some eyewitnesses that were there.

You have two 110 story office buildings.
You don't find a desk.
You don't find a chair.
You don't find a telephone, a computer.
The biggest piece of a telephone I found was half of a keypad,
and it was about this big:
(makes a shape with his hand about 4 inches in diameter)
The building collapsed to dust.
