World Trade Center

The September 11 attacks, colloquially known as 9/11, were a coordinated series of suicide attacks perpetrated by the Islamist terrorist organization al-Qaeda against the United States in 2001. Nineteen terrorists hijacked four airliners, then flew one into each of the Twin Towers at the World Trade Center in New York City. The third plane crashed into the Pentagon, the headquarters of the United States Department of Defense, in Arlington County, Virginia. The fourth plane crashed in a rural Pennsylvania field during a passenger revolt. In response to the attacks, the United States launched the global war on terror, seeking to eliminate hostile groups deemed terrorist organizations, and the governments purported to support them. This foreign policy agenda was conducted over the next two decades.

The original World Trade Center (WTC) was a complex of seven buildings in the Financial District of Lower Manhattan in New York City. Built primarily between 1966 and 1975, it was dedicated on April 4, 1973, and was destroyed on September 11, 2001 after two hijacked planes were flown into the towers in a coordinated terrorist attack. The complex included the 110-story-tall Twin Towers, at the time of their completion the tallest buildings in the world, with the original 1 World Trade Center at 1,368 feet (417 m), and 2 World Trade Center at 1,362 feet (415.1 m); they were also the tallest twin skyscrapers in the world until 1996, when the Petronas Towers opened in Kuala Lumpur, Malaysia. The other buildings in the complex were the Marriott World Trade Center (3 WTC), 4 WTC, 5 WTC, 6 WTC, and 7 WTC. The complex contained 13,400,000 square feet (1,240,000 m2) of office space and, prior to its completion, was projected to accommodate an estimated 130,000 people.
