Why did the World Trade Center towers collapse? Weren't they designed to be earthquake-proof and impact-proof? The 110-story twin towers of the World Trade Center, which stood at a height of 1,353 feet, were designed to withstand earthquakes as well as impacts like that of a plane.

The more likely cause of the buildings' collapse was the resulting fire, exacerbated by the huge quantities of jet fuel present. | ||
