Here is the funny part.
"The scientific paper Active Thermitic Material Discovered in Dust from the 9/11 World Trade Center Catastrophe
conclusively shows the presence of unignited aluminothermic explosives in dust samples from the Twin Towers"
Explosive Residues: Energetic Materials and the World Trade Center Destruction
Now, un-ignited? Think about this. These people would have us believe that thermite was used to make the fires hot enough to melt steel yet it did not ignite some of this nano thermite. And if I remember the story right this dust was collected four months after the attack. I could be wrong about that I was laughing rather hard while trying to read these reports....
Fact is that there has been no physical evidence presented to disprove any of the major points of the 911CR.
Oh and thermite? Not much more than aluminum and rust....Bet you can find these trace amounts in any collapsed office building.....
