hi cameron fox,
Of course there was dust from the first collapse!
But ca. 15 sec. before the second collapse there is a NEW BIG SMOKE on the ground. I watched it again and again! There is no other explanation that there wer huge ground-level explosions prior to collapse No.1 and No2. The smoke came from the space between the towers near to WTC3 (Marriot Hotel). Why do you think the people filming the vid pointed the camera to this area prior to both collapses.

There's even an alternate angle camera shot of the first tower. No smoke is seen at ground level because of other buidlings in the way but there is a few rumbles which could be explosives going off, the camera shakes quite a bit then the building collapses in free fall.[edit on 2-12-2006 by jinsanity]

for those floors that it damaged I can see. But 90 or so floors weren't damaged so something else would have had have taken out those joints and bolts. And the heat wasn't that bad to melt steal because there are pictures of people standing in the holes the airliners made. and minutes after they crashed into the building.

The building did NOT collapse at Free fall. Everyone in here knows it. Even the pod people.
How could the WTC towers collapse in only 11 seconds (WTC 1) and 9 seconds (WTC 2)—speeds that approximate that of a ball dropped from similar height in a vacuum (with no air resistance)?
NIST estimated the elapsed times for the first exterior panels to strike the ground after the collapse initiated in each of the towers to be approximately 11 seconds for WTC 1 and approximately 9 seconds for WTC 2. These elapsed times were based on: (1) precise timing of the initiation of collapse from video evidence, and (2) ground motion (seismic) signals recorded at Palisades, N.Y., that also were precisely time-calibrated for wave transmission times from lower Manhattan (see NCSTAR 1-5A).
As documented in Section 6.14.4 of NIST NCSTAR 1, these collapse times show that:
“… the structure below the level of collapse initiation offered minimal resistance to the falling building mass at and above the impact zone. The potential energy released by the downward movement of the large building mass far exceeded the capacity of the intact structure below to absorb that energy through energy of deformation.
Since the stories below the level of collapse initiation provided little resistance to the tremendous energy released by the falling building mass, the building section above came down essentially in free fall, as seen in videos. As the stories below sequentially failed, the falling mass increased, further increasing the demand on the floors below, which were unable to arrest the moving mass.”
In other words, the momentum (which equals mass times velocity) of the 12 to 28 stories (WTC 1 and WTC 2, respectively) falling on the supporting structure below (which was designed to support only the static weight of the floors above and not any dynamic effects due to the downward momentum) so greatly exceeded the strength capacity of the structure below that it (the structure below) was unable to stop or even to slow the falling mass. The downward momentum felt by each successive lower floor was even larger due to the increasing mass.
From video evidence, significant portions of the cores of both buildings (roughly 60 stories of WTC 1 and 40 stories of WTC 2) are known to have stood 15 to 25 seconds after collapse initiation before they, too, began to collapse. Neither the duration of the seismic records nor video evidence (due to obstruction of view caused by debris clouds) are reliable indicators of the total time it took for each building to collapse completely.

It wasn't just bolts, it was welds. The bolts are called "erection bolts", for actually erecting the building. Afterwards, the connections are welded.
The heat from the fire could easily cause any weld to fail.

hi cameronfox,
do you know who operates this seismographs. I don't. the NIST people are part of the cover-up too... Trust your own eyes. I do...
I know that the smoke in the vid can't be a video manipulation. I know that it was there.
Why do you think the FBI needs months to release surveillance vids from the pentagon hit? Why are they so careful? They check every single frame of the vids they release. Why this caution. I mean they are comletely innocent, they have nothing to hide. Evil Osama did it.

the only problem with your theory cameron is that in controlled demolitions the building picks up speeds as the floors continue to collapse for whatever reason. This is consistent with controllem demo's and consistent with the towers collapse.

Bsbray...Why put words in my mouth? I was speaking mostly of the reports of "Truck Bombs" and Several more UNACCOUNTED planes. Remember Bush was flying around in AirForce One... becasue of FALSE reports.
That day was hectic.
