Then how do you explain the traces of military grade thermite in the dust residue? I also saw pics of the uprights still glowing from the thermite, with cuts at 45 degrees. What about the firefighters that mentioned flowing molten metal?
I suppose it is possible that both were used, I could see that as reasonable. I wouldn't totally rule out the possibility of redirected energy, but the evidence for thermite being used is too great to just ignore.
