The government didnt tell me anything.
1,000s of independent engineers, metallurgists, fire fighters, architects told me.

Does this mean you would Pull It for Larry if he ordered you to?
I thought you put me on ignore when your feathers were molting. Are you going to allow Dave to answer for his self?
Building SEVEN didn't even have a aircraft hit it.

I remember getting a call from the, er, fire department commander, telling me that they were not sure they were gonna be able to contain the fire, and I said, "We've had such terrible loss of life, maybe the smartest thing to do is pull it." And they made that decision to pull and we watched the building collapse.

.... Apparently, the Government wants nothing to do with engineers learning from this collapse how to build safer structures. I wonder why. Maybe the engineers would have learned some other things if they had full access to the evidence.......
Also, check out the date of this article. Obviously could not have picked a better day for minimum exposure of this information.

"This is almost the dream team of engineers in the country working on this, and our hands are tied," said one team member who asked not to be identified. Members have been threatened with dismissal for speaking to the press."

if you had actually bothered to read that thread you would have seen that those cars were moved there....
6. Using the images from another website may or may not have been a mistake. Some readers are certain that the two rows of vehicles in the parking lot shown were moved there. However, there isn't any photographic evidence to support this. Undisturbed dust UNDER the vehicles shows these vehicles were there all along since the collapse. For those who are sure they were moved, consider these facts: And if the vehicles were moved, would any tow truck driver go to the trouble to "sort" the vehicles in a such a way to move them to the parking lot shown, orienting them all the same way and grouping them according to damage? When there were hundreds of destroyed vehicles to be moved? Tow-truck and flat bed drivers are paid by the vehicle, and the more vehicles they move the more money they make. A totaled vehicle is still a total loss and not worth sorting.

Thermite is in that manual, yet is one of the most poo-hooed CT ideas. This is a whole new light on it for me.

Can you or anyone please show me that the fireman's manual states that thermite should be tested for in the case of a steel building collapse ? Thanks.

Duh.
Didn't the fireman just do that in the video? Do you even bother to look at the OP before you start on your flaccid denier schtick?
The two towers were the first structures outside of the military and nuclear industries designed to resist the impact of a jet airliner, the Boeing 707. It was assumed that the jetliner would be lost in the fog, seeking to land at JFK or at Newark. To the best of our knowledge, little was known about the effects of a fire from such an aircraft, and no designs were prepared for that circumstance. Indeed, at that time, no fireproofing systems were available to control the effects of such fires.
Figure 3 shows the comparative energy of impact for the Mitchell bomber that hit the Empire State Building during World War II, a 707, and a 767. The energy contained in the fuel is shown in Figure 4. Considerations of larger aircraft are shown in Figures 5 and 6. The physical sizes of these aircraft are compared with the size of the floor plate of one of the towers in Figure 7. These charts demonstrate conclusively that we should not and cannot design buildings and structures to resist the impact of these aircraft. Instead, we must concentrate our efforts on keeping aircraft away from our tall buildings, sports stadiums, symbolic buildings, atomic plants, and other potential targets.
