1. The PRESENCE of molten steel, if there was any, proves nothing, as it is IMPOSSIBLE to tell if it was made molten PRIOR TO, or AFTER the collapse.
If I may so bold as to disagree, I think it
can prove something, and particularly if we have some eye witness testimony to when it existed.
Specifically, if people claim to have seen molten steel in the debris pile, and it indeed can be shown that molten steel did exist in the debris pile, this indicates that severe fires existed in the debris piled (we know this already, by hey...).
Now for severe fires to exist in the debris pile, there must firstly be sufficient fuel in the debris to produce such fires, and given that this fuel came from the buildings, this means the buildings had sufficient fuel for severe fires
before collapse, thus adding another nail in the well-nailed coffin of the hopelessly deceased notion that the fires in the towers were small and insignificant.
Further, it
suggests (rather strongly) that these serious fires in the towers survived collapse and continued to burn, further supporting their seriousness prior to collapse.
What I think you mean, and of course what is wholly true, is that the presence of molten steel, at any point in the incident, in no way provides the most remote scrap of evidence in support of a controlled demolition.
But then us sane people already knew that.
2. I have provided earlier in this thread, links to photos of MOLTEN aluminum, copper, tin, and even glass, and I am telling you, to an untrained (or perhaps even a trained) eye, you cannot tell them apart. Therefore, visual observation of molten substances, PERIOD, means diddly squat in terms of the presence of MOLTEN STEEL.
On this point I'd like to briefly disagree also, if I may be so bold... the photos provided are always of the metals under very low light conditions. It is true that all metals give off black body radiation, and that the incandescence can be used to estimate the temperature of the metal, however the intensity of the radiation varies remarkably, and further the colour is consistent. Thus if the molten metal is the right colour to be molten steel, it must be the right temperature to be molten steel also, and again, while in darkness the metals cannot be distinguished this is not true under direct sunlight. Aluminium, for example, gives off much less black body radiation than steel, and thus under direct sunlight aluminium is easily identifiable because it's silver, not a bright cherry red.
The obvious culprit is, of course, glass. And I find it odd that glass is so seldom cited. Glass was in ample supply in the buildings and debris, glass has a low melting point, and glass gives off very bright black body radiation with a different colour range to metals, thus glass can appear to be like molten steel when it is nowhere near the same temperature.
Having said all this, I'm inclined to agree with you; I do not know why we still have a debate on it. Actually that's a lie, I do know why. Conspiracy Theorists are ignorant of the fact that molten metal actually hurts their theory, and have this ridiculous notion that somehow molten metal could only be produced by a Controlled Demolition. In truth the exact opposite is true - a CD would not produce molten metal, or any description. Only a very severe fire would.
