You are talking about the fuel fires, while hot, not being hot enough to melt the steel structure. I haven't subscribed to that argument because you don't need to melt it. You just need to soften it. However, this is not needed for the inside job theory to be correct. I do wager though that all the funkiness surrounding the 9/11 report will continue to fuel these speculations, which I do not discount, by the way. People should learn it is just better to be straight up.
