The official version is that it's molten aluminum mixed with all of the other stuff inside the building and plane. You're building a straw man talking about "molten steel".
To find the version of events you're supposed to be debunking, go
here, section 11.
The fire in WTC did burn hot enough to melt light gauge aluminum. But most of that aluminum was on the outside of the building. Yes the plane would have brought some of it in with it but the fire did not burn hot enough or long enough to cause the molten aluminum to begin pooling.
You can melt aluminum in your barbecue if you stoke it long enough with lighter fluid. But within 20 seconds of the time you stop stoking it with fuel it stops melting and stops pooling and again becomes a solid. Since the 9/11 fire was was a very cool oxygen starved fire I find it impossible to believe that there was any metal of any type other that lead that could be melted at those low temperatures. Lead was mostly outlawed even when the towers were built, so that cannot be the answer.
It has to be Thermite of some-type. Nothing else could produce so much molten metal in the basements.
Now for those that just want facts remember the following. The facts for melting points of metals can be answered by any structural engineering or industrial welding corporation you call. These facts will be the same if you look for them in the 1960's, 70's *80's or 2011. Why, because the facts of question 2 and 3 have existed and been known since the 1940's. Steel temperature melting points is a science that has been studied since ancient times. In the last century it has become nearly a perfect science. So the facts about when steel melts at different grades is absolute depending on the grade of steel.
Once you have those facts then you will know for sure that there was nothing in the towers that could burn hot enough to cause molten steel to pour out of the tower. Once you know these facts then it is just a process of elimination and logic on what was melting the steel in the towers. That should make it much easier to determine what possible things exist in the world that could cause molten steel to pour out while the tower is still standing. The facts regarding metals melting points are not open to debate, they are known and have been known and accepted as facts longer than you and I have been alive. So focus on the facts, not all the other disinformation. Then from there work yourself through the other questions.
The people responsible for 9/11 want you to wear yourself out and to get lost in all the other theories so you do not focus on the absolute facts that are already known about metals melting points. All the proof you need is right here in and the video at the top. If you don't understand this, then any other research on 9/11 would be pointless. Stick with the facts that cannot be ruled out by anyone no matter how many other points of view are presented.
Metal's melting point are are well known fact and a true science that has been known in the modern age for most metals for over 100 years. Jet fuel temperatures are well known for the last fifty years. The history of structural steel buildings collapsing due to fire for the last 100 years is also well known, none had ever collapsed before 9/11 and none has collapsed since 9/11.
