World Trade Center (2001–present)
The buildings are among many created by the World Trade Centers Association. The original World Trade Center featured the landmark Twin Towers, which opened in 1973, and were the tallest buildings in the world at the time of their completion. They were destroyed on the morning of September 11, 2001, when al-Qaeda-affiliated hijackers flew two Boeing 767 jets into the complex in a coordinated act of terrorism. The attacks on the World Trade Center killed 2,753 people. The resulting collapse of the World Trade Center caused structural failure in the surrounding buildings as well. The process of cleaning up and recovery at the World Trade Center site took eight months, after which rebuilding of the site commenced.

According to U.S. State Department cable of February 2010, released by WikiLeaks in 2011, the FBI has investigated another suspect, Mohammed al-Mansoori, who had associated with three Qatari citizens who had flown from Washington to London on the eve of the attacks, after allegedly surveying the World Trade Center and the White House. U.S. law enforcement officials said that the information about the four men was "just one of many leads that were thoroughly investigated at the time and never led to terrorism charges". An official added, however, that the three Qatari citizens have never been questioned by the FBI. Eleanor Hill, the former staff director for the congressional joint inquiry on the September 11 attacks, said the cable reinforces questions about the thoroughness of the FBI's investigation. She also said that the inquiry concluded that the hijackers had a support network that helped them in different ways. The three Qatari men were booked to fly from Los Angeles to Washington on Sept. 10, 2001, on the same plane that was hijacked and piloted into the Pentagon on the following day, but did instead fly from Los Angeles to Qatar, via London. While the cable states that Mansoori would be currently under investigation, U.S. law enforcement officials said that was no active investigation of him or of the Qatari citizens mentioned in the cable.
