The collapse of the world trade center occurred on tuesday, september 11, 2001, after two commercial airliners hijacked by al-qaeda were deliberately flown into the twin towers of the world trade center complex in new york city as part of the september 11 attacks.
Why the Twin Towers Collapsed?
The Twin Towers’ collapse on September 11, 2001, is one of the most devastating events in history. Nearly 3,000 people were killed, and the entire world was shocked and confused. In the years since, many theories have been put forth to explain why the Twin Towers collapsed, but there is still no definitive answer as to what caused the tragedy.
The most widely accepted theory is that the Twin Towers collapsed due to the intense heat from the burning jet fuel that caused the steel beams to weaken and eventually collapse. When the hijacked planes crashed into the towers, the intense heat caused the steel beams to expand and ultimately buckle, leading to the collapse of both towers. This theory is supported by evidence from the National Institute of Standards and Technology (NIST), which found that the heat from the burning jet fuel caused the steel beams to weaken and eventually fail.
Another theory suggests that the collapse of the Twin Towers was since the towers were not designed to withstand the force of the impact from the hijacked planes. The towers were designed to withstand wind loads but not the impact of a hijacked plane. The NIST investigation also found that the towers were not designed to withstand the impact of a plane, and that the planes
