ATTENTION PEOPLE. For those still quacking about smoke over wtc 7 being all from WTC 5 & 6:
Footage unequivocally shows the smoke emerging from the the building:

Starting 45-50 seconds in all the way to the 2 minute mark.

This one shows it from the onset of the footage.
Enough of the silly notion that the smoke was coming purely from the adjacent structures. The video doesn't isolate a single instance in time like a still shot does, so there's doubt with this.
As I told Senemenut (sp?) before. Fear of another aircraft attack has nothing to do with it. It may have been a factor on that particular day, but firefighters know full well that collapse is ALWAYS a risk in a situation where fires are burning. It doesn't matter if it's a house, or a skyscraper. It doesn't matter if they think the risk is of partial or total collapse, they take a huge risk by entering building in that condition. Being RIGHT about it doesn't change it, and infact that's why most rational people don't consider the idea that people were right this time around to be of any significance. You need to SHOW that their knowledge cannot be accounted for with concerns that are epressed on a near daily basis, which often times come to fruition unfortunately in some form or another. You have failed to do so.
ATTENTION PEOPLE. For those still quacking without reading first. Nobody has stated that the smoke was coming purely from the adjacent structures. NIST didn't do so, I didn't do so.
For those still linking the same snippet of the Spak video for the 3rd 4th 5th... time without understanding the argument.
In that video we see without any doubt that the SW corner of floor 29/30 is on fire prior to noon.
A little later that fire went dead (exactly as observed by NIST). It's about noon and we see a nice spiral of bright smoke billowing up along the edge of the building. That appearance might be mistaken as smoke from all floors just like Rotanz interpreted it as "burning inferno" but...
...a little change of the wind shows that most of the windows are unbroken. Hence, the smoke couldn't have come from undamaged windows. It's kind of impossible. Furthermore the presented fire didn't spread far before dying down.
Instead of a burning inferno we witness a nice spiral of bright smoke that does exactly what the flow pattern of wind predicts. Nothing more and nothing less.
So what tells a picture like that?
It shows a lot of smoke that looks like coming from the building. According to sun and shadows that image was taken in the afternoon. In the afternoon the fires at 22 and 19 already went dead hours earlier. Nevertheless we see two puffy extensions looking like coming from 22 and 18. But there was no reported fire at 18.
Hence, these extensions in the smoke are either part of the billowing up smoke or part of photo manipulation.
The same linked video helps us to see that there is no smoke from 19 or 18 at about 1pm. Instead we can identify two sources of heavy smoke. One source is the debris right below the damaged corner. The other source is WTC6. Furthermore, there is no visible smoke or fire or soot from 11,12,13 right below the intersection of both smoke columns.
Right at that time the NIST simulation reached 500°C-1000°C in exactly that area.
At about 2pm fire was observed at the east face at 11 and 12.
These fires will consume the entire floors while NO fire above floor 13 and after 1pm was observable at the east, west or north face.
So the initial question was, what is the difference between the early fires (prior to 1pm) at 19, 22, 29, 30 and the later fires (after 2pm) at 7,8,9,11,12,13?
Finally the remaining later fires spread through the floors...
...while the simulated fires are a little more purposeful.
