What the dust cloud hid on September 11: simulation shows World Trade Center collapse without smoke or debris

SAPO Notícias11 September 2026 at 11:55

A computer simulation has again shown, 25 years later, the exact moments of the World Trade Center collapse in New York, revealing what the dust cloud from the September 11, 2001 attacks usually obscured. The animation allows us to observe the towers' structure collapsing without the presence of smoke or debris, offering a clearer view of the phenomenon.

The video simulation was shared on the anniversary of a quarter of a century since the terrorist attacks that killed almost three thousand people. The simulation strips away the visual elements that normally accompany the actual footage of the collapse, allowing for a more detailed analysis of the falling mechanics.

The presentation of these seconds from a new perspective has generated renewed interest in the technical analysis of what happened that day. The massive dust cloud that formed during and after the towers' collapse has always obscured part of the events, and the simulation helps to better understand the sequence of facts.

Young man manages to lose 124 pounds without surgery or pen and becomes weight loss coach

David John Castañeda, an American from Texas, reached 210 kg at 19 years old, suffering from binge eating that led him to eat until feeling pain. His daily menu included eight-egg omelettes, entire packages of pasta, countless slices of bread, and large portions of tortillas, rice and meat. After realizing he wasn't eating out of hunger, but out of habit, and that he had lost the ability to recognize satiety, David decided to change his lifestyle without resorting to surgery or medications.
