On September 11, 2001, two planes crashed into the World Trade Centers in New York City, resulting in the collapse of the iconic buildings. The destruction of the Twin Towers was a tragic event that shook the nation, and people around the world. But how did the Trade Centers collapse?

The collapse of the Trade Centers was caused by a combination of factors. First, the planes that crashed into the buildings caused extensive structural damage. The intense heat of the fires that resulted from the crashes weakened the steel columns and trusses, which were responsible for supporting the buildings.

Second, the impact of the crashes caused the buildings to sway, which weakened the supporting columns. This swaying weakened the columns further and caused them to fail. The failure of the columns caused the buildings to collapse.

Third, the combination of the weakened steel columns, weakened trusses, and swaying of the buildings caused the upper floors to pancake down on the lower floors. This pancaking caused the buildings to collapse.
