I don't have the time to reproduce the basis for all of those things so here's just one...
(If you take the ten minutes that it takes to have a look at this and then come back there might be something to actually discuss.)
Earlier on this thread there is a link to a site called "Firefighters for 9/11 Truth" and if it's not on this thread then you should be able to find it in a flash with Google.
On that site is a link several videos and from memory one of them is of the chief engineer of NIST giving a presentation to a group of students some time after the event. Included in that video is footage of a small group of firefighters being interviewed about what they saw in the wreckage of the WTC towers. In that interview they state unambiguously that they saw molten metal. I have seen this interview quoted by other sources on the internet but this is the most recent that I've seen and any of the sources will do.
So, after you've watched the interview you might agree that there are a limited number of reasons why that footage exists.
Top of my list is either: a) The men are playing a joke, whether they are professional actors or actual firefighters; or b) The footage is genuine and should be considered when analysing the available information to try and determine what actually happened and who is responsible.
For what it's worth I am assuming that the answer to the above is (b) for two reasons which are: that there is an enormous amount of corroborating evidence that is consistent with their claims; and that this interview has been used as a reference by Steven Gage who would undoubtedly lose most of his well earned credibility if it was found to be fraudulent.
