I read the front page of the main document, and one of the links off to their link to the "proof" that the heat wasn't hot enough to menlt the steel which was in a report by a BBC newepaper which said "fire reached 800 C, hot enough to melt steel." Which this person then followed up with "link to steel facts" in which the melting point of steel was posted.
Now... because you cite a newspaper which do get facts wrong ALL the time (take when my high school's science building burned halfway out in 1996? [6 or 7] for example, they reported it in 5 big county and adjacent county newspapers and even on the news and not a SINGLE report got more than the burning part right) so citing one with what could be an error in it as a source for why you're right... I don't think is correct.
Aside from that, the MELTING point of steel which this person linked to is the point at which steel becomes liquid like, NOT the point at which it becomes maleable enough to bend under wieght.
Need some more counter-info? Rebar, the stuff used to reinforce cement, comes in 1/4, 3/8, 1/2, and 1 inch thick standard consumer grade probably up to 2" and down to 1/8 (don't know for sure... only bought what I listed)
I made an entire metal frame with 3/8" rebar that I cut and bent by hand using nothing but my own body to make 90o or more bends. Yes it was a pain in the ass, but the point is, I (6' 2" 135 pound weak limbed man at the time) was able to bend and break more than 12 feet of 3/8" steel rebar for my project at room temperature, with out a bending tool. (I had a hack saw for cutting it, btw) The project also had a 1/2" rebar spine if I remember correctly which bent 90o at the bottom, which I also bent by hand (though I used an extension bar for leverage on this 1/2".)
Obviously steel reinforcement bar (rebar) is weaker than steel building gerters... BUT... these already heated parts on the building were then being compressed and tentioned by the floors above bearing down on them, and at a heated state steel becomes much easier to bend as it becomes more maleable (though still not melted.) Because of the combined probelms of the possibly loosened joints from impact, the heat of the fuel making the steel more maleable, and the tension of the whole upper stories of the building on affects parts... it seems quite possible to have happened the way it did.
If you want to see how easy it is to bend some rebar, go on down to a local hardware store and buy a piece of 3/4, 3/8, and 1/2 inch steel rebar. I guarantee you it's bendable by hand with no tools.
If you want to get crazy... heat it up in something as simple as a campfire (make sure you're wearing welding style gloves) and then give it a bend.
It's strength somes in cool rigidity. Once it's changed just enough it gives way like a charm.
That is the addressing of the steel bending possibility... I don't care to, but I may write more later... :-/
Did the government ever give us it's sources used when writing their reports? Did they give us scientific explanations, or other places they found their info? I don't think so.
As a neutral I don't trust anyone... it's sad sometimes, but I still am comapassionate to my fellow human being though I may not trust them.
I prove things to myself and sometimes others who want to know through my own life experiences and the observed experiences of others. For me, my own experiences in playing with fire, metal, and tension - compression system gives me feeling that the building legitimately could have fallen from a plane with full tanks ramming into it.

There is a group of engineers that made a program all about the building probelms for public television (PBS) in the USA... According to them it had a lot of problems in it's internal design anyway. I'm not saying they're right, but it was a large range of engineers from all civilian (from what I saw, though I didn't watch the whole program) engineering groups and they did go into great detail about a lot of the whole mess. [none of which I have posted at all] It'd be kind of neat to post that as a counter-example if this truly is some kind of warped debate. ;-p

Adios!
