WTC conspiracy.. not again!?

In this video, besides from screaming people, you can clearly see molten metal flowing from the outside of the WTC tower just prior to collapse. The burning jet fuel and office materials which are thought to have reached a maximum of 650 °C can melt aluminumm, but that doesn't glow, so it must be iron or steel . So there must be a hotter source. 650 °C is enough to weaken steel by about 50%, but the design of the building more than allowed for this. Also pools of molten metal were found in the rubble that were molten and hot for many days after the collapse. This gives credence to the theory that thermite or more likely thermate was used to bring the buildings down. Thermite and thermate are mixtures that when ignited burn at temperatures of up to 2500°C and can easily melt through steel. Sulpher was found on a few salvaged bits of WTC steel, the rest was shipped of to be recycled. Thermate contains sulpher and was hot enough to fuse it with the steel. An in-depth paper, which describes the point in much more detail, on the collapse, by Steven E. Jones a professor of physics at Brigham Young University who conducts research in nuclear fusion and solar energy, and 9/11 researcher. And some more on the thermite hypothesis. Now there just needs to be a way for a group of people to carry something like two thousand kilograms of explosives and thermate into the buildings and it could be done. That's 10 trips with 10 people, each carrying 20kg. 'Maintenace' workers could have done this in the weeks before 9/11 I don't know, these last couple of years I've really been swayed between believing nothing besides nasty hijackers happened, or hijackers plus knowledge of the government, or hijackers and knowledge and cooperation by the government which would be totally horrendous. Whatever be the case, I think much more research should be put into this. Also in this long (2 hour) video presentation by Steven E. Jones he also goes into (@1:08:50 time) Bin Laden saying that he did not do it. And that in the tape where Bin Laden says he has done it, the man saying it clearly is a doppelganger. As blog readers don't want to read into the paper I just wanted to add something that looks like visible evidence. Click the picture for full size. See the diagonally 'cut' beam in the background? That clearly looks like it has been cut and not teared. Also you can see dark colored stuff on it, which looks like solidified molten metal. This lends support to the thermite theory.
