“Fuel fires cannot melt steel.”
The 9/11 Truthers have mislead you. Conspiracy theorists cherry pick some isolated facts while distracting you from the big picture. Fuel fires lasting for hours will weaken steel, and then the structure sags and joints break and once floors start to pancake, the force of that collapses the building. This also answers the other favorite conspiracy talking point, that a jet cannot “knock down” a sky scraper. The impact and fire weakened the buildings, and that was enough. It was not like those old Godzilla movies where a guy in a costume pushes over model buildings.
The other conspiracy involves the collapse of the WTC 7 building....
The truthers can’t understand the colossal amount of energy released when the buildings collapsed, look at the video and you see giant pieces of steel being thrown outwards landing on buildings all around the towers....
