DUDE, right here in your cited video Robertson says no melted steel. Darn! 3:15...
Ooops, at 3:30, the video you use for "evidence" lies about steel, says it was vaporized, when it was corroded. You post a video which lies, like you do. Not surprised, but why do you post false information? The video is like NAZI propaganda, designed to fool those who fail to read the real reports or use knowledge to check and see if the video is telling the truth. You failed to check it out. You post lies and can't figure out you are spreading lies.
If you are able to be a skeptic and bring knowledge to the table, able to think critically, as in you have intelligence; you will be extremely upset when you open your eyes and find 911 truth is one big lie, and you were fooled. But if you can't comprehend that soon, you are lost in the pit of ignorance where 911 truth finds those few who can't think for themselves, the few 911 truth fools.
My God...watch to the end. They were showing to show Robertson was lying.
