seriously dude? the fire doesn’t need to be hot enough to melt steel it only has to be hot enough to degrade the integrity of the steel, heat a steel beam to the point where it glows red and nothing will happen, put that same piece of steel under a stress load and it fails.

try it at home yourself get your charcoal grill really really hot then start stacking bricks on the food grate and see what happens.

I understand that physics and have not argued that softened steel is just as strong as non-softened steel. I still think it's arguable that THAT much (little) jet fuel softened THAT much steel to THAT degree. Maybe it did. I'm not convinced.

I still don't believe that Dr Judy Wood is wrong about the time taken to dislodge each succeeding floor on the way down.
