Creative Speculation

While first responders may be super men, you're claiming that they can do metallurgical analysis with their eyes? I have to doubt that.

There were thousands of tons of aluminum in the buildings, and aluminum is easily melted at the temperatures in an office fire. Why is it, then, that there aren't any reports of molten aluminum? My guess is that some people did see it but just assumed it was molten steel, whereas other people who saw it realized that they couldn't identify it by sight, so they just reported seeing "molten metal." At any rate, there is no physical evidence of molten steel in the debris, so any wild theories that use that as a premise aren't credible. And even if there was evidence of molten steel, why would you take that as evidence of controlled demolition? Please name a demolition method -- even a hypothetical one -- that would leave molten steel weeks after the attack? Finding molten steel would be an interesting puzzle to solve, but just jumping to vague and irrational conclusions to feed your conspiracy theory inclinations doesn't do the trick.
