While it may take 2500 degress F to melt Carbon Steel, it only takes 1100 degrees F to make it lose half of its strength. So how is a building supposed to support itself at half strength? Thats not even including the columns the planes knocked out |

So these buildings that burnt forever didn't collapse but the little jet fuel that remained (most burnt up outside) in the towers caused them to collapse?
