Re: 9/11 Debate Reply #15 – March 19, 2021, 11:11:08 AM Quote from: LP on March 19, 2021, 10:50:49 AMAs part of basic bushfire research, CSIRO did extensive testing of various building materials, and found steel and some metals although less likely to catch would also suffer the most catastrophic failures at lower temperatures or from being heated to high temperatures. The structural members buckle and fold like a melted straw once they get above a critical temperature.The longest survived structures in bush fires are solid log constructions, because although they burn the timber chars on the outside but doesn't become structurally weaker in the process lasting much longer before failure. Sort of makes sense when you see the charred forests after regional fires. For this reason they are now developing new building codes that may permit construction up to 10 stories structurally built out of wood.It's probably fair to say the Twin Towers must have been exposed to some extreme heat, they were basically 100 story chimneys. I think CSIRO and other local scientists debugged the 9/11 conspiracies very well a long time back on The Conversation website, you might still be able to find that information.There will always be alternate opinions, some because they just refuse to accept what they think is right is wrong, others because they have some external motive affecting their judgement, others because they want there to be a conspiracy.All that is debunked lp.I watched 20minutes of what was posted before. ive seen others talking about it too.No skyscraper has ever been brought down by fire.....ever......anywhere. 3 happened on the same day.Jet fuel can't burn hot enough to get to the heat required for the type of failure seen.Even still, all beams and columns are fire rated to withstand fire and heat for 2-3 hours. They were completely down in an hour.They fell at free fall.Clearly if this was the perfect storm of a freak accident and a 1 in a trillion event, you'd want to look at evidence.....but that was shipped off immediately to China and destroyed. Maybe it wasn't a freak accident and maybe they didn't want to look at the evidence.Fwiw, military grade thermite was found in an a nearby apartment where it was analysed in a lab.The way some beams were sheared/cut is not consistent with a fall but rather....yep....thermite and controlled demolition.
