The collapse of the world trade center occurred during the terrorist attacks of september 11, 2001, after the twin towers were struck by two hijacked commercial airliners. One world trade center (wtc 1, or the north tower) was hit at 8:46 a.m. Eastern time and collapsed at 10:28 a.m.
How Did World Trade Centers Collapse?
The collapse of the World Trade Center towers on September 11th, 2001 is still one of the most shocking events in modern history. People around the world were shocked to see the two iconic towers of the New York City skyline falling apart. The question of how the Twin Towers collapsed has been on the minds of many ever since.
The official explanation for the collapse of the Twin Towers is that the intense heat from the jet fuel ignited by the airplanes caused the steel structure of the buildings to weaken and eventually collapse. The intense heat from the burning jet fuel had a direct impact on the steel columns, beams and trusses of the buildings. The heat caused the steel to expand and weaken, leading to the eventual collapse of the towers.
The impact of the planes on the Twin Towers was also an important factor in their collapse. The force of the two aircraft hitting the towers at high speed caused major structural damage, which weakened the steel structure. The impact of the planes also sent shock waves through the buildings, which caused the floors to start to buckle and sag. This created a downward force, which further weakened the steel structure and eventually led to the collapse of the towers.
The fires that resulted from the burning jet fuel were also an
