The 9/11 Attacks on USA

 That morning, four planes flying from the northeastern United States to California were hijacked by 19 al-Qaeda terrorists. The hijackers were organized into three groups of five hijackers and one group of four. Each team had one hijacker who had received flight training and took control of the aircraft. Their clear aim was to crash each plane into a prominent American building, causing mass casualties and partial or complete destruction of the targeted buildings.

The first plane to hit its destination was American Airlines Flight 11. It was airlifted to the North Tower of the World Trade Center complex in Lower Manhattan at 8:46 a.m. Seventeen minutes later at 9:03 a.m., the South Tower Tower was hit by United Airlines Flight 175. Both 110-story towers collapsed within an hour and forty-two minutes, resulting in the collapse of some World Trade Center buildings including 7 World Trade Center, and severe damage to the surrounding structures.

A third plane, American Airlines Flight 77, from Dulles International Airport, was hijacked in Ohio. At 9:37 a.m., it crashed on the west side of the Pentagon (US military base) in Arlington County, Virginia, causing a collapse of part of the building. A fourth, and final aircraft, United Airlines Flight 93, was flown near Washington, D.C. The passengers tried to control the flight away from the hijackers and eventually diverted the plane to its intended destination; struck a field near Shanksville, Pennsylvania at 10:03 p.m. Investigators have determined that the purpose of Flight 93 could be the White House or the American Capitol.

Following the attack, allegations quickly spread to al-Qaeda. The United States, led by George W. Bush, officially responded by launching the Terrorist War on Afghanistan to oust the Taliban, who had not complied with US demands to oust al-Qaeda from Afghanistan and al-Qaeda leader Osama bin Laden. Bin Laden fled to White Mountain where he was attacked by U.S. forces, but managed to escape. [6] Although Bin Laden initially denied his involvement, in 2004 he formally committed himself to the attack. [2] Al-Qaeda and bin Laden cited the support of Israel by the U.S., the presence of US troops in Saudi Arabia, and the punishment of Iraq as insurgents. After fleeing exile for nearly a decade, Bin Laden was in hiding in Abbottabad, Pakistan and was later killed during Operation Neptune Spear on May 2, 2011.

The demolition of the World Trade Center and nearby infrastructure has severely damaged New York City's economy and caused a global recession. Many countries have strengthened their anti-terrorism laws and increased law enforcement and intelligence agencies to prevent terrorist attacks. American and Canadian airports were closed until September 13, while trade on Wall Street was closed until September 17. Many closures, evictions, and cancellations were followed, with respect or fear of further attacks. The cleaning of the World Trade Center site was completed in May 2002, and the Pentagon was renovated within a year. Construction of the World Trade Center building began in November 2006, and the building opened in November 2014. [7] [8]

The attack resulted in 2,977 deaths, more than 25,000 injuries, and major long-term health consequences, in addition to at least $ 10 billion in infrastructure and property damage. [9] [10] It remains one of the deadliest terrorist attacks in human history and the single largest strike of firefighters and law enforcement officials in the history of the United States, in which 340 people were killed [11] and 72, [12] [13] respectively. Numerous monuments have been erected, including the National September 11 Memorial & Museum in New York City, the Pentagon Memorial in Arlington County, Virginia, and the Flight 93 National Memorial at the Pennsylvania disaster area.
