I wanted to bring this point up before but I forgot...
It's right in NIST's FAQ. They don't deny there being molten steel there. They just say the cause is irrelevant (caused AFTER the collapse, ie not the impact or fires).
They don't say that there WAS molten steel either.
Well, it's now after, and the answer is the same. So what does it matter? All they are saying is that it's conceivable.Did they determine this before or after they started investigating the pile?
See the WTC7 FAQ:Also, for clarification, that FAQ only seems to mention WTC1 and 2, not 7.
