As generally accepted by the community of specialists in structural mechanics and structural engineering (though not by a few outsiders claiming a conspiracy with planted explosives), the failure scenario was as follows [..

World Trade Center controlled demolition theories contend that the collapse of the World Trade Center was not solely caused by the airliner crash damage that occurred as part of the September 11 attacks, and the resulting fire damage, but by explosives installed in the buildings in advance.[1] Controlled demolition theories make up a major

The cleanup was a massive operation coordinated by the City of New York Department of Design and Construction. On September 22, a preliminary cleanup plan was delivered by Controlled Demolition, Inc. (CDI) of Phoenix, Maryland.[92] Costing hundreds of millions of dollars, it involved round-the-clock operations with many contractors and subcontractors

The three-page white paper titled Salient points with regard to the structural design of The World Trade Center towers described an analysis of a Boeing 707 weighing 336,000 pounds (152 t) and carrying 23,000 US gallons (87 m3) of fuel striking the 80th floor of the buildings at 600 miles per hour (970 km/h). It is unclear whether the effect of jet fuel and aircraft contents was a consideration

The cleanup of the World Trade Center site involved round-the-clock operations and cost hundreds of millions of dollars. Some surrounding structures that were not hit by the airplanes still sustained significant damage, requiring them to be torn down. Demolition of the surrounding damaged buildings continued even as new construction proceeded on the Twin Towers' replacement, the new One World Trade Center, which was opened in November 2014.

The original World Trade Center in Lower Manhattan, New York City was destroyed during the terrorist attacks of September 11, 2001, after being struck by two hijacked commercial airliners. One World Trade Center (WTC 1) the "North Tower" was hit at 8:46 a.m. Eastern time and collapsed at 10:28 a.m. Two World Trade Center (WTC 2) the "South Towe

from the north by Barclay Street, West Broadway, Vesey Street, and Washington Street. This would become the site of 7 World Trade Center, although that building was not added until much later. The two blocks to the west and east of the "cork" were occupied by the New York Telephone Company Building and the Federal Building, respectively

In 1958, Rockefeller established the Downtown-Lower Manhattan Association (DLMA), which commissioned Skidmore, Owings and Merrill to draw up plans for revitalizing Lower Manhattan. The plans, made public in late June 1960, called for a World Trade Center to be built on a 13-acre (53,000 m2) site along the East River, at the South Street Seaport, one of the Lower Manhattan ports that had seen a continuous decline in business over the past decade.[11][12] The site would be bounded clockwise from the south by Old Slip, Water Street, Fulton Street, and South Street,[13][14] and the complex itself would be located on "a two-story platform that would supersede and displace the conventional street grid".[1

south by Old Slip, Water Street, Fulton Street, and South Street,[13][14] and the complex itself would be located on "a two-story platform that would supersede and displace the conventional street grid".[12] The proposed complex included a 900-foot-long (270 m) exhibition hall, as well as a 50- to 70-story building with a
