The videos and photographs have been discussed at length; to summarise, it's impossible for them to be molten steel. The metallurgical analysis you're referring to doesn't exist; nobody has presented metallurgical analysis showing that any previously molten, now solidified material from anywhere in the WTC complex is steel.

Please do recount the metallurgical analysis in detail, so we can explain to you that it doesn't say what you want it to. The rest, we can disregard, because it amounts to nothing more than anecdotes.

On the contrary, it requires considerable ignorance of metallurgy to believe that molten metal at such a high temperature can only be molten steel.

Me: So what you're saying is that, if the load carrying ability of the lower structure is reduced to the point where it can no longer support the load above it, it will collapse without a jolt, right?

Tony Szamboti: That is right
