"PERHAPS not melted"?? How about the fact that "melted steel" was ABSOLUTELY never part of the official report, but 911 truthers keep claiming it was?! It's not as if there is little difference between "melted" and "weakened". There is a HUGE difference! One didn't happen- one DID happen! There is plenty of photographic evidence showing the exterior walls buckling just before the collapse. Of course you just ignore that in favor of making your blanket, conspiritorial conclusion about "controlled demolition".
