The Science of 9/11

[Starlord]

The science of 9/11, does it suggest controlled demolitions?

 

My personal conclusion for this is that all three towers were destroyed by controlled demolition.  I will cite the following evidence

1.      Explosive material was found in the dust

I have read the paper by Harrit, Jones et al entitled ‘Active Thermitic Material Discovered in Dust from the 9/11 World Trade Center Catastrophe’.    There is a good deal of evidence in there that strongly indicates the presence of nano-thermite in the dust.

 

2.      Independent computer modelling of Building 7 by the University of Alaska Fairbanks in ‘A Structural Reevaluation of the Collapse of World Trade Center 7’ concludes

‘It is our conclusion that the collapse of WTC 7 was a global failure involving the near simultaneous failure of all columns in the building and not a progressive collapse involving the sequential failure of columns throughout the building’

In my opinion a controlled demolition would explain the above type of failure.

 

3.      Evidence of high temperatures.

There are various photographs of deformed steel components from the towers suggesting they had been subjected to high temperatures. 

 

4.      Freefall.

David Chandler did a video analysis of the Building 7 collapse and concluded that the collapse was in freefall (i.e. little or no resistance).  A controlled demolition would explain this behaviour.

 

5.      Sulfidation

This phenomenon was found to have occurred in material from 9/11 and was mentioned in the FEMA report.  It occurs at around 1000 degrees Celsius.
