World Trade Center

The original World Trade Center was a complex with seven buildings featuring landmark twin towers in Lower Manhattan, New York City, United States. The complex opened on April 4, 1973, and was destroyed in 2001 during the September 11 attacks. The site is currently being rebuilt with five new skyscrapers and a memorial to the casualties of the attacks. As of September 2011, only one skyscraperhas been completed with four more expected to be completed before 2020. One World Trade Center will be the lead building for the new complex and is expected to be finished by 2013. A sixth tower is still awaiting confirmation to be built. At the time of their completion, the original 1 and 2 World Trade Center were the tallest buildings in the world, surpassing the Empire State Building, also inManhattan. The complex was designed in the early 1960s by Minoru Yamasaki and Associates of Troy, Michigan, and Emery Roth and Sons of New York.[2] The twin 110-story towers used a tube-frame structural design. To gain approval for the project, the Port Authority of New York and New Jersey agreed to take over the Hudson & Manhattan Railroad, which became the Port Authority Trans-Hudson (PATH).Groundbreaking for the World Trade Center took place on August 5, 1966. The North Tower (1) was completed in December 1972 and the South Tower (2) was finished in July 1973. The construction project involved excavating a large amount of material, which was later used as landfill to build Battery Park City on the west side of Lower Manhattan. The cost for the construction was $400 million($2,169,167,354 in 2011 dollars).[3] The complex was located in the heart of New York City's downtown financial district and contained 13.4 million square feet (1.24 million m2) of office space.[4][5] The Windows on the World restaurant was located on the 106th and 107th floors of 1 World Trade Center (the North Tower) while the Top of the World observation deck was located on the 107th floor of 2 WorldTrade Center (the South Tower). Other World Trade Center buildings included the Marriott World Trade Center; 4 World Trade Center; 5 World Trade Center; 6 World Trade Center, which housed the United States Customs. All of these buildings were built between 1975 and 1981. The final building constructed was 7 World Trade Center, which was built in 1985. The second King Kong was filmed in 1976 with somescenes mentioning and showing the World Trade Center. The World Trade Center experienced a fire on February 13, 1975, and a bombing on February 26, 1993. In 1998, the Port Authority decided to privatize the World Trade Center, leasing the buildings to a private company to manage, and awarded the lease to Silverstein Properties in July 2001. On the morning of September 11, 2001, Al-Qaeda-affiliatedhijackers flew two 767 jets into the complex, one into each tower, in a coordinated terrorist attack. After burning for 56 minutes, the South Tower (2) collapsed, followed a half-hour later by the North Tower (1), with the attacks on the World Trade Center resulting in 2,753 deaths.[6] 7 World Trade Center collapsed later in the day and the other buildings, although they did not collapse, had tobe demolished because they were damaged beyond repair. The process of cleanup and recovery at the World Trade Center site took eight months. The first new building at the site was 7 World Trade Center, which opened in May 2006. The Lower Manhattan Development Corporation (LMDC), established in November 2001 to oversee the rebuilding process, organized competitions to select a site plan andmemorial design. Memory Foundations, designed by Daniel Libeskind, was selected as the master plan, which included the 1,776-foot (541 m) One World Trade Center, three office towers along Church Street and a memorial designed by Michael Arad. On September 11, 2001, terrorists hijacked American Airlines Flight 11 and crashed it into the northern facade of the north tower at 08:46 a.m., the aircraft...
