That is why this subject could be directly "On Topic" Seriously, though - WTC7 was a large repository for precious metals. Check out this image: http://911research.wtc7.net/wtc/evidence/gold.html ... not sure how much of it was palladium, however <g> > NP: Even if thermite was used, what mechanism could possibly keep pools of molten steel - molten - beams dripping - glowing - for WEEKS after they were melted. It's just not possible unless you want to bring in a LENR CANR angle!
