The September 11 attacks, also known as 9/11, were a series of coordinated terrorist attacks carried out by the extremist group Al-Qaeda on September 11, 2001, in the United States. The attacks had a profound impact on global politics, security measures, and international relations. Here’s a timeline of the major events on that day:

8:46 AM: American Airlines Flight 11, a Boeing 767 with 92 people on board, is hijacked and flown into the North Tower of the World Trade Center (WTC) in New York City. The impact creates a gaping hole in the building between the 93rd and 99th floors.

9:03 AM: United Airlines Flight 175, another Boeing 767 with 65 people on board, is hijacked and flown into the South Tower of the WTC. The impact causes a massive explosion and a subsequent fire.

9:37 AM: American Airlines Flight 77, a Boeing 757 with 64 people on board, is hijacked and flown into the western facade of the Pentagon, the headquarters of the United States Department of Defense, located in Arlington, Virginia.

9:59 AM: The South Tower of the WTC collapses, less than an hour after being hit. The collapse is attributed to the damage caused by the impact and the resulting fires weakening the building’s structural integrity.

10:03 AM: United Airlines Flight 93, a Boeing 757 with 44 people on board, is hijacked. Passengers on board learn of the attacks on the WTC through phone calls and decide to resist the hijackers. The plane crashes into a field in Pennsylvania, after passengers’ efforts to regain control.

10:28 AM: The North Tower of the WTC collapses, approximately 102 minutes after being hit. The collapse is attributed to similar reasons as the South Tower.

5:20 PM: World Trade Center Building 7, a 47-story building located near the Twin Towers, collapses. The building had been damaged by debris from the Twin Towers’ collapse and had been burning for hours.

In addition to these events, there were numerous other incidents, including the grounding of all flights in the United States, the evacuation of government buildings, and the implementation of heightened security measures across the country.

The 9/11 attacks resulted in the deaths of nearly 3,000 people from more than 90 countries and caused significant damage to infrastructure and property. It led to a global war on terror, with the United States initiating military operations in Afghanistan to dismantle Al-Qaeda and overthrow the Taliban regime.
