Before and after 2001, in countries all around the world including the US, there are examples of modern steel buildings catching fire, becoming fully involved in some cases, burning all night in some cases, and never collapsing. It's old news, though the most recent was the Grenfell Tower building in London about 6 months ago. I say again soldier, a man like you will dismiss any and all information that threatens your view of the world. I'm not trying to change your mind or anybody else. If you were actually curious about these things, you would have already informed yourself, years ago. Clearly you're not curious. Carry on.
