Moby, let me add something to your story.
First of all FEMA: "The performance of WTC7 is of significant interest because it appears the collapse was due primarily to fire, rather than any impact damage from the collapsing towers."
The damage can be ignored in that case according to the official report.
Today I saw in the newspaper that they are going to demolish the Deutsche bank near the WTC, it will take a year or something, maybe it is better to raise some fire I assume then...
Further at 9/11 wtc6 received the full load of both twin towers and it was still standing. How can you make it plausible that wtc7 then would collapse as a CD-clone ? Using the same statistics as in this thread I now say
"All CD experts that I've seen so far talking objectively about wtc7 (directly and not via third parties or obscure compiled documents on the net) say it is a CD without any doubt"
But to be honest, as lay persons we have to accept what is told, but there is enough room for open discussion because the wtc7 case is not closed. There is not yet an official explanation about the kind of collapse, it is no pancake collapse, it is no progressive collapse, it is a CD-clone caused by fire according to FEMA, laughable... if you look at the videos you clearly see that the structures are broken simultaneously, it was not really a clean collapse but obviously a job done by experts according to Danny Jowenko (CD expert with almost 30 years experience, listed on implosionworld). It's also very logical that a building that will collapse due to something random will not fall in that way. If you use Greening's math or a similar math for wtc7 (although it is no kind of top-down demolition) you really have a problem, a big big problem. You need an initial momentum with a vector pointing to the centre of the earth and that can only be obtained when the building is pulled simultaneously at the supporting columns on some levels. It should gather some fall speed first. If we again notice that the official (quoted at top) report ignores the damage. Then (uncontrolled random raging) fire should be able to pull a building like a CD. Further there are no calculations that prove this, it is just an assumption and nothing more.
