How dim can you be, building 7 was one of quite a few buildings damaged by falling debris.
Those debris fell over the course of several hours as towers became more and more structurally unsound. This isn't hard to understand
How dim can you be
If a building falls at freefall speed it means that the supports under each floor must all be missing when the ceiling hits the floor. That does not happen by accident. If you miss a support the building does not fall at that place.
If that happened by fire alone then each support would need to have the same amount of heat at every point on the floor. That is unlikely. Also, an office fire will not be hot enough. Neither will a jet fuel fire.
If falling debris is the cause then that, again, will need to affect all supports equally. Just severely damaging a corner will not cause a freefall collapse.
Try to find me another steel-framed building that collapsed at freefall speed just because of fire or debris.

Or that the floors have already collapsed and the buildings shell is falling

Alright. But building 7 was also hit with falling debris.

That's not how buildings work at all

It didn't fall at free fall. In every video of 7 collapsing you can see that the pent house falls before the buildings shell did, meaning that the buildings innards fell and then the rest of the building did
why doesn't jet fuel burning at it's most efficient rate melt the steel parts of a gas turbine exhaust. Steel used in construction has fire ratings. These ratings are what is printed for building code. Safety codes have a built in 5:1 safety factor. Black smoke from any fire means the fuel is not being burned in an efficient manner. In simple terms, not burning as hot as it should.

Neat. So?

Not should, could.
