You seem to be laboring under a misconception, Marokkaan.
We aren't disputing that steel beams can melt; they can, and do, at a very specific temperature (>2800 degrees Celsius, IIRC). What we are disputing is that one cannot tell with a simple cursory glance what composition a pool of liquid molten material is without some sort of chemical composition test.
No one has disputed that eyewitnesses saw pools of molten metal. But the EVIDENCE (such as the melting point of steel being FAR above the highest recorded temperatures of the debris pile) points to it being any one of the number of other metals that comprised the WTC towers structure. Copper or aluminum have far lower melting points and appear to look almost exactly the same as a pool of liquid molten steel when in their liquid state. The likelihood is far greater that the molten (i.e. liquid) metal pools observed were not, in fact, steel, but were copper or aluminum, both of which comprised a goodly percentage, if not the majority, of the metal found in the WTC construction. So we are not calling your witness a liar; we are calling him mistaken, and pointing to the science that backs up our points. You have yet to point to any; merely cherry-picking a single quote made by someone who may or may not realize that steel cannot possibly melt at the temperatures measured in the debris pile. They can soften, certainly, and bend and warp and twist, but they could not have melted into an entirely liquid pool of metal.
