September 11, 2001, is a day etched in the memories of people around the world. The terrorist attacks on the World Trade Center in New York City, resulting in the collapse of the Twin Towers, left an indelible mark on history. One of the most commonly asked questions about that fateful day is which tower fell first. In this article, we will delve into the timeline of events and examine the evidence to determine which tower collapsed first.
The Morning of September 11
On September 11, 2001, a series of coordinated terrorist attacks were carried out in the United States. Four commercial airplanes were hijacked by terrorists affiliated with Al-Qaeda. Two of the planes, American Airlines Flight 11 and United Airlines Flight 175, were intentionally crashed into the Twin Towers of the World Trade Center in New York City.
Flight 11 Hits the North Tower
At 8:46 a.m., American Airlines Flight 11, a Boeing 767 aircraft, crashed into the North Tower (1 WTC) of the World Trade Center. The impact and subsequent fires caused significant damage to the tower's structure.
Flight 175 Hits the South Tower
Seventeen minutes later, at 9:03 a.m., United Airlines Flight 175, also a Boeing 767 aircraft, crashed into the South Tower (2 WTC) of the World Trade Center. The impact and fires also caused significant damage to the tower's structure.
The Collapse of the Towers
The fires from the plane crashes weakened the structural integrity of both towers. The South Tower, which was hit second, collapsed first at 9:59 a.m. The North Tower, which was hit first, collapsed at 10:28 a.m.
Why Did the South Tower Collapse First?
Several factors contributed to the South Tower collapsing before the North Tower:
- Impact location: The impact from Flight 175 was more centralized and higher up on the South Tower, causing more extensive damage to the tower's core columns.
- Fuel load: The South Tower had a smaller fuel load, which resulted in a smaller fire, but also meant that the fuel burned off more quickly, leading to a more rapid weakening of the structure.
- Structural damage: The South Tower's structural system was more severely damaged due to the impact, which compromised its ability to redistribute loads and resist collapse.
Conclusion and Timeline
In conclusion, the South Tower (2 WTC) collapsed first at 9:59 a.m., followed by the North Tower (1 WTC) at 10:28 a.m. The timeline of events is as follows:
- 8:46 a.m.: Flight 11 hits the North Tower (1 WTC)
- 9:03 a.m.: Flight 175 hits the South Tower (2 WTC)
- 9:59 a.m.: The South Tower (2 WTC) collapses
- 10:28 a.m.: The North Tower (1 WTC) collapses
