All the recovered steel was not inventoried before it was shipped away and sold for scrap. Bush said we were attacked so you don't investigate an act of war (attack), the country "responds". So we are left with little hard evidence and lots of images and videos many of them seem to be tampered with.

The steel did not turn to dust. The towers took 10-15 seconds to collapse and so this appears to be gravity at play. Some believe that this was too fast. This is an assertion not a fact.

Some are studying the collapses and the debris images to this date and discovering new information and new understanding of what happened. All three towers moved a bit before they "let go and collapsed" and this indicates that in the period of slight motion preceding the collapses, only detected with computers and sophisticated software analysis of the vids, that the structure was failing progressively and there was load / stress redistribution going on. Over time this left too little of the structure to support the loads and the buildings then collapsed from their own weight.

This was possible because of the unique design of the three towers which had long span open office floors with no columns interrupting them. So their design was partially their undoing.

We don't know what got the load / stress distribution and progressive failures going. Fire seems like an unlikely cause to do this in such a short time and without high enough temps. However once the structure was losing columns etc. it could not support the weight and gravity, as in a CD brought it down.

I personally wouldn't spend $50 to read Wood's book which if I understand correctly presents a DEW or some other form of energy which was used to "dustify" the towers. I reject that thesis for the reasons stated above.

I don't think we know either of these numbers precisely... perhaps the steel installed might be able to be accurately established, but I doubt the recovered steel weight can be accurately established.

But your concept is good.

Jeffrey Orling Wrote:Jack,

Makes perfect sense. But not all the steel was sold for scrap. Some of it was taken and stored in a hanger in JFK and some I read was taken up to MA and stored for some reason. Some of it was used for memorials around the country.

If you know how much steel was removed, saved and stored please provide the number. Same thing for all the steel. We don't have the actual structural drawings for the towers, all the other buildings, the sub basements and so forth to do a calculation. I suspect the steel came from multiple sources in separate contracts. Only some of them are available as far as I can tell. If you have a list of all the contracts please provide it. And tell me how we could know we have ALL the contracts without comparing them piece by piece to the structural drawings?

I am doing a job now with some steel, not very much and I still don't know the total weight, although I know the size of all the members. Sections are often field cut leaving scraps which are returned to the dumpster. But I could go in, measure and calculate it.
