You demonstrate your complete ignorance of the subject with this comment.
I assume your statement means that I am ignorant of all of the stupid "alternate" (=conspiracy) theories. I've looked at each one. They are based on falsified info and false theories of how things work or don't work. I have a feeling that "knowledge" to you means accepting the stupid and disproven conspiracy theories. A self-fulfilling cycle. Well I know what they are and I reject them, as have all but the fringe elements.
There is no need for thermite in the equation. BTW - you are clearly clueless as to what thermite really is, how it works, etc. It is not what you would use for the job. In fact, demolition teams don't use it to take down large buildings. Has it not occurred to you that if thermite (or whatever) could take down big buildings so well, then demo crews would use it as standard operating procedure. They don't BECAUSE IT WOULDN'T WORK.
There is a show on TV called "Forged in Fire" - watch it sometime; especially the outdoors episodes where they have to build a forge out of coal fires. Getting to high enough temperatures to forge steel is pretty easy. Your confidence that it couldn't happen in the buildings with all of the airplane fuel + combustible materials in the buildings is totally off base. It's nothing more than an uninformed opinion that you have somehow translated into being total unquestionable truth (a classic conspiracy theory move)
Steel didn't need to "melt". It only needed to weaken. Much like my blacksmith who makes horse shoes to fit my horse. He doesn't melt the shoe into molten metal. He heats it until it has become soft enough to bend.
I didn't realize that you're a metallurgist - or are you just repeating something you read that confirms your bias? There are plenty of experts in metallurgy that say what I am saying. Anyhow, the thermite idea is very stupid and it's sad that you don't understand that, but repeat the notion with such confidence.
Ever seen an airplane crash. Thick black smoke, ok?
You're acting as if we didn't all see airplanes hit the buildings. What? I supposed that was done with secret Area 51 holographic projections. You're out of your mind along with all the other 9/11 "truther' nut jobs.
If you presented you theories as questions - like "I'm concerned that the official narrative isn't true because I don't see how xyz could happen, can you help me understand?" that would be acceptable. But you don't. You come out and state that the US government for sure committed mass murder because you know XYZ beyond a shadow of doubt.
