But even if the fires in WTC reached 2700 F, still, the WTC towers cannot collapse in 11 seconds at free fall speed, because each tower has 500,000 tons of RESISTANCE underneath them. That resistance has to be removed first, such as with controlled demolition. Buildings dont have zero resistance, thats why the roof over you in your house doesnt come down on you. The foundation has to be destroyed first.
Steel doesn't need to melt and become liquid for a building to collapse. Strength is substantially lost way before that with increased temperature:

Since the structural safety factor for buildings is normally 2.0, you would think it makes sense that a 1100F (600C) fire can result in failure of an already compromised structure
https://en.wikipedia.org/wiki/Factor_of_safety
Also, the downward momentum of the huge falling mass makes it pretty much unstoppable. Even Controlled demolition relies on explosives being on selected locations only, so whether the collapse points were created by airplanes or explosives is irrelevant for the purposes of the quoted argument.
No expert on the whole subject, but where are the proofs of any team setting up and hiding all the fancy explosives and then having the planes hit exactly where the explosives were installed, without setting them off immediately?
No you are missing the point. Doesn't matter if the steel melted or weakened. The WTC had about 110 floors. Damaging a few floors at the TOP of the building isn't going to destroy 100 floors below them at the rate of FREE FALL speed. Each tower collapsed in 11 or 12 seconds. That's near the rate of free fall. The bottom line is that you CANNOT remove 500,000 tons of RESISTANCE as though it were thin air. There is NO WAY around this. It's basic common sense.
Why do you think no high rise structure has ever complete collapsed from fire before? None. Zero. You have zero evidence that it's possible for a skyscraper to collapse from fire.
What downward momentum? Remember the North Tower was hit by the first place near the very TOP of it. Watch the video of the first plane to hit and you will see this. There's NO WAY the top floor is gonna plunder the 110 floors below it at the rate of free fall speed, turning 500,000 tons of resistance into thin air! NO WAY. 100 PERCENT IMPOSSIBLE.
Even if there was a pancake collapse, with each floor progressively adding weight toward a downward momentum, that kind of collapse would still be a lot slower and less complete, resulting in only a partial collapse. There is no way around this. A pancake collapse absolutely could not achieve the kind of collapse that happened. That was well established back in 2006. You seem way outdated on this issue. It's like you are dishing out ideas that people were back in 2001 and have learned nothing since then nor kept up with any 9/11 research since 2001. Shame on you.
As to the proof of people planting explosives, well geez, are you a little kid? Do you think the people who planted the explosives would leave proof of that for someone like you to find? LOLOLOL ROFTL!!!!!!! You're joking right? That's a really dumb expectation.
But to answer your question:
1. A WTC employee named Scott Forbes claimed that there was a 36 hour power down in the WTC the week prior to 9/11. During that time, explosives or thermite or whatever devices could have been planted in the WTC.
2. George Bush's brother, Marvin Bush, was in charge of security of the WTC. He could easily remove that security to allow bombs or thermite to be planted.
3. Thermite residue was found in the WTC dust back in 2006. There are several scientific papers published about this. We discussed this many years ago. It's old news. Where were you? Google "Steven Jones" or "Niels Harritt". This is hard evidence that explosive material was used to blow up the WTC.
4. Many people heard the sound of bombs from the WTC on 9/11. There are many hours of video footage of witnesses reporting this. Even Peter Jennings of ABC and Dan Rather of CBS said that bombs or explosives must have been used. You can watch the footage of them saying that online. We've all seen it thousands of times.
5. William Rodriguez, a janitor of the WTC, said that he felt an explosion from the basement of the WTC push UPWARD from underground, when he was on the ground floor. He has given this testimony many times.
6. There is video footage taken on a tripod which shows that about 12 seconds before the WTC collapse, the ground shook under the tripod, which means that something was detonated UNDERGROUND just before the WTC collapse. This corroborates the testimony of William Rodriguez. You can see this video on YouTube. I've posted it before.
Every researcher knew all this stuff back in 2006. It's been posted many times in many threads in this forum. It's old news. Where have you been since 2001? Geez. How can you not be aware of all this?! What kind of truth seeker are you?!
