Why did the Twin Towers collapse? These are the scientific reasons behind 9/11

In the collective memory of our society there is an image that has marked the recent history of Western countries: the fall of the Twin Towers. The 9/11 attacks marked a new course in the international politics of the United States, and of many countries of the European Union. 20 years later, the fall of the two North American buildings is still one of the most representative images of the 21st century.

During these 20 years, there have been many analyzes that have been given on the causes, motivations and effects of the 9/11 attacks. Even science has tried to give a scientific answer about the collapse of the two towers after the impact of two Boeing 767s on the morning of September 11, 2001.

Why did the Twin Towers fall on 9/11?

At 8:45 in the morning, a plane full of passengers crashed into the north tower and the building began to burn. It was like this for 102 minutes until it collapsed. In this collapse it only took 11 seconds to fall to the ground.

At 9:03 a.m., a second Boeing 767 hit the other tower. Collapse in just 9 seconds after being on fire for about 50 minutes.

The image of the two famous Twin Towers burning ran around the world. It was a symbol that fell under the terrorist threat. The two buildings were not prepared for an attack like this, and in less than 15 seconds, both had fallen into the flames.

According to engineer Eduardo Kausel, emeritus professor of the Department of Civil and Environmental Engineering at the Massachusetts Institute of Technology, speaking to BBC Mundo, “the answer accepted by all serious people is that the towers collapsed because they were the object of a terrorist attack. ».

But Kausel, who led the studies a year later to find out the scientific causes of the collapse after 9/11, admitted that if the buildings had not had fire, they would never have collapsed.

The emeritus professor pointed out in his conclusions two basic factors that allowed the collapse of the Twin Towers: the great and severe structural damage caused by the collisions of the planes in the buildings and the chain of fires that spread through several of the floors.

This fatal combination was the scientific trigger for the Twin Towers to collapse in less than 12 seconds. “And if there had only been a fire, without the structural damage, they would not have collapsed either,” said the emeritus professor in his study.

Finally, the professor also made special mention of the impact of the planes, “they were air bombs” , which made it easier for the flames to appear in a mixture of fire and air that was fatal to the two buildings that suffered the 9/11 attacks.
