The September 11, 2001 attacks were a series of suicide attacks upon the United States of America conducted on Tuesday, September 11, 2001. According to the official 9/11 Commission Report, nineteen men affiliated with Osama bin Laden and Al-Qaeda, a loose network of Sunni Islamist terrorists, simultaneously hijacked four U.S. domestic commercial airliners.
Two were crashed into the World Trade Center in Manhattan, New York City — one into each of the two tallest towers, about 18 minutes apart — shortly after which both towers collapsed. The third aircraft was crashed into the U.S. Department of Defense headquarters, the Pentagon, in Arlington County, Virginia.
The fourth plane was crashed into a rural field in Somerset County, Pennsylvania, 80 miles (129 km) east of Pittsburgh, following passenger resistance. The official count records 2,986 deaths in the attacks.(Gilbert,2002)
In the immediate aftermath of the September 11 attacks, the United States and other countries around the world were placed on a high state of alert against potential follow-up attacks. Civilian air travel across the U.S. and Canada was — for the first time ever — almost completely suspended for three days (as part of Operation Yellow Ribbon), with numerous locations and events affected by closures, postponements, cancellations, and evacuations. Other countries imposed similar security restrictions. In the United Kingdom, for instance, civilian aircraft were forbidden to fly over London for several days after the attacks.(Dean,2002)
Security measures
It is barely surprising, especially when considering the monumental extent of the damages incurred in terms of losses of property and human life that the attacks carried out against America on the 11th of September 2004 collectively impacted American society in a lasting manner. One of the most immediate indications of such an impact, furthermore, was of a marked increase in discrimination against all individual with Asian backgrounds, especially those from regions with strongly Islamic roots................
