Explanation:
The attacks of September 11, 2001 were a series of four terrorist attacks committed on the morning of Tuesday, September 11, 2001, by 19 members of the al Qaeda jihadist network, by hijacking commercial aircraft to be impacted against various objectives, causing the death of 3016 people (including the 19 terrorists and the 24 disappeared) and leaving more than 6000 injured, as well as the destruction in New York of the entire complex of World Trade Center buildings (including the Twin Towers) and serious damage to the Pentagon building (headquarters of the Department of Defense of the United States, in the state of Virginia), an episode that would precede the war in Afghanistan and the adoption by the US Government and its allies of the policy called "War on Terror".
The attacks were committed by 19 members of Al Qaeda, divided into four groups of kidnappers, each with a terrorist pilot who would be responsible for piloting the plane once the crew of the cabin was reduced. American Airlines Flight 11 and United Airlines Flight 175 were the first to be hijacked, and both were crashed into the Twin Towers of the World Trade Center, the first against the North Tower and the second shortly thereafter against the South, causing that both skyscrapers collapsed in the next two hours.
The third hijacked plane belonged to American Airlines flight 77 and was used to hit against the west side of the Pentagon in Virginia. The fourth plane, belonging to flight 93 of United Airlines, did not achieve any objective having crashed in the open field, near Shanksville, Pennsylvania, after losing control in the cabin as a result of the confrontation of passengers and crew against the terrorist command. It aimed at the United States Capitol, in Washington D.C.
