The Devastating Aftermath of 9/11: A Look Back at the Collapsed Buildings

September 11, 2001, is a day that will be etched in the memories of people around the world for generations to come. The terrorist attack on the World Trade Center in New York City resulted in the loss of thousands of lives and caused unprecedented destruction. The collapse of the Twin Towers, which were the iconic symbols of American power and prosperity, sent shockwaves across the globe.

The Collapse of the Twin Towers

The Twin Towers, also known as the North Tower (1 WTC) and the South Tower (2 WTC), were the tallest buildings in the world at the time of their completion. They were designed by the architectural firm Skidmore, Owings & Merrill, and were constructed using a steel frame with a central core. The towers stood at a height of 1,368 feet (417 meters) and 1,362 feet (415 meters) respectively.

On the morning of September 11, 2001, a group of terrorists affiliated with al-Qaeda hijacked four commercial airplanes. Two of the planes, American Airlines Flight 11 and United Airlines Flight 175, were intentionally crashed into the Twin Towers. The impact of the planes and the subsequent fires caused the structures to collapse. The South Tower collapsed at 9:59 a.m., followed by the North Tower at 10:28 a.m.
