How Long Did It Take the Twin Towers to Fall?
The Twin Towers of the World Trade Center were two of the most iconic buildings in the world, and their fall on September 11, 2001 was a defining moment in American history. When the towers collapsed, the world watched in shock and horror as the two buildings that had stood tall for over 30 years were reduced to rubble in mere seconds. But how long did it take for the Twin Towers to fall?
The collapse of the Twin Towers happened in two distinct stages. The first was the initial collapse of the South Tower, which began at 9:59 a.m. EST on September 11. The South Tower collapsed in just 10 seconds, sending a huge cloud of dust and debris into the air and causing a massive shockwave that could be felt and heard for miles. The North Tower followed suit at 10:28 a.m., collapsing in just 12 seconds.
The time it took for the Twin Towers to collapse was incredibly fast, and it is a testament to the amount of energy that was released from the impact of the planes and the subsequent fires that raged through the buildings. The fires burned at temperatures of up to 2,000 degrees Fahrenheit, weakening the steel components of the building and eventually leading to their collapse.
