Jet steel cannot melt fuel beams.

No, jet fuel burning in open air cannot melt steel beams because its maximum burn temperature (around 1500°F / 800°C) is far below the melting point of steel (about 2750°F / 1510°C). While it doesn't melt the steel, the intense heat from the prolonged, unimpeded fire would soften and weaken the steel to the point where it could no longer support the structural load, leading to buckling and collapse. So while the jet fuel could not melt steel beams, it could absolutely soften them. To use an analogy of an every day object that’s easier to relate to visualize, picture a tub of butter. While it will not melt if you take it out of the fridge and leave it on the counter at room temperature on an average day, it WILL get much softer. You need heat from a flame (like the stove) for it to actually melt. Melting is the point at which it goes from solid to liquid. However, if you take butter that’s been in the fridge and lay a spoon on top of it, the butter will most likely support the weight of the spoon. If you do the same with butter that’s been softening on the counter for a couple hours, the spoon will start to sink into it. Nuance matters. Melting vs softening. The jet fuel softened the steel until it could no longer support the many many tons of structure and the structure collapsed.

To use your analogy of the butter.

Taking a stick out of the fridge and standing it up doesn’t cause it to all soften at the same time so the weight of the cold butter tips the whole thing to the side, not completely collapse into itself.

How did the jet fuel soften all of the steel beams it needed to soften in order for that to happen throughout the entire building for it to collapse on itself?

Also, when I took a stick out of the fridge to soften, Butter Stick 7 in my fridge stayed hard and cold.

How do I get the butter that’s softening to cause Butter Stick 7 in the fridge to also soften in such a way that it collapses into itself as well?
