Swann has questioned whether 7 World Trade Center collapsed on September 11, 2001, the way authorities said it did. See also 9/11 conspiracy theories. The National Institute of Standards and Technology  (NIST) investigated the events of 7 World Trade Center. NIST determined that diesel fuel did not play an important role, nor did the structural damage from the collapse of the Twin Towers. Fires burned out of control during the afternoon, buckling critical columns, and ultimately causing the building to fall downward as a single unit. The fires, which were fueled by office contents and burned for seven hours, along with the lack of water, were the key reasons for the collapse. This made the old 7 WTC the only steel skyscraper at the time to have collapsed from fire. The NIST report found no evidence supporting the conspiracy theories that 7 World Trade Center was brought down by controlled demolition.

On September 11, 2001, two of four hijacked planes were flown into the Twin Towers of the original World Trade Center, and the towers subsequently collapsed. 7 World Trade Center collapsed due to fires and structural damage caused by heavy debris falling from the collapse of the Twin Towers. The other buildings within the World Trade Center complex were damaged beyond repair and soon after demolished. The collapse of the Twin Towers caused extensive damage to other surrounding buildings and skyscrapers in Lower Manhattan, and resulted in the deaths of 2,606 people, in addition to those on the planes. Since 2001, most of Lower Manhattan has been restored, although there has been controversy surrounding the rebuilding. Many rescue workers and residents of the area developed several life-threatening illnesses that have led to some of their subsequent deaths. A memorial at the site was opened to the public on September 11, 2011, and the museum opened in 2014. In 2014, the new One World Trade Center, at and formerly known as the Freedom Tower, became the tallest building in the Western Hemisphere, while other skyscrapers were under construction at the site.

The original World Trade Center was destroyed in the terrorist attacks of September 11, 2001; One World Trade Center was the first of the famous Twin Towers to be struck by a hijacked aircraft, at 8:46 a.m EDT, and the second tower to collapse, at 10:28 a.m. Of the 2,977 victims killed in the attacks, 1,402 were in or above the North Tower impact zone. The North Tower was replaced by the present-day One World Trade Center tower, which was opened in November 2014 as the lead building of the redeveloped World Trade Center site.

On September 11, 2001, the structure was damaged by debris when the nearby North Tower of the World Trade Center collapsed. The debris also ignited fires, which continued to burn throughout the afternoon on lower floors of the building. The building's internal fire suppression system lacked water pressure to fight the fires, and the building collapsed completely at , according to FEMA, while the 2008 NIST study placed the final collapse time at . The collapse began when a critical internal column buckled and triggered structural failure throughout, which was first visible from the exterior with the crumbling of a rooftop penthouse structure at 5:20:33 pm. The collapse made the old 7 World Trade Center the first tall building known to have collapsed primarily due to uncontrolled fires, and at the time, the only steel skyscraper in the world to have collapsed due to fire.

The Twin Towers of New York City's World Trade Center collapsed after being deliberately struck by two commercial passenger jets during the September 11 attacks. A total of four commercial aircraft were hijacked by al-Qaeda terrorists on 9/11 and two of those were crashed into the Twin Towers. American Airlines Flight 11 was crashed into the north side of the North Tower (One World Trade Center) and United Airlines Flight 175 was crashed into the south side of the South Tower (Two World Trade Center). The collapse of the Twin Towers destroyed the rest of the complex, and debris from the collapsing towers severely damaged or destroyed more than a dozen other adjacent and nearby structures. The South Tower collapsed at 9:59 am, less than an hour after being hit, followed by the North Tower at 10:28 am. Later that day, the nearby Seven World Trade Center collapsed at 5:21 pm from fires that had started when the North Tower collapsed. As a result of the attacks to the towers, a total of 2,763 people died including 2,192 civilians, 343 firefighters, and 71 law enforcement officers as well as all the passengers and crew on the airplanes, including 147 civilians and the 10 hijackers.

On September 11, 2001, two of the four hijacked planes were flown into the Twin Towers of the original World Trade Center, and the towers collapsed. The 7 World Trade Center was not struck by a plane, but collapsed because of heavy debris falling from the impacts of planes and the collapse of the North Tower. The other buildings of the World Trade Center complex were damaged beyond repair and soon after demolished. The collapse of the Twin Towers caused extensive damage to surrounding buildings and skyscrapers in Lower Manhattan, and resulted in the deaths of 2,606 people, in addition to those on the planes. Many rescue workers and residents of the area also developed several life-threatening illnesses and some have since died.

On the morning of September 11, 2001, Islamic terrorists affiliated with Al-Qaeda hijacked American Airlines Flight 11 and United Airlines Flight 175, both which were en route to Los Angeles, and intentionally crashed them into the two main towers of the World Trade Center. The towers collapsed within two hours of the collisions. 2,606 people, including 2,192 civilians, 71 law enforcement officers, and 343 firefighters, who were in the towers and in the surrounding area died in the attacks, as well as 147 civilians and the 10 hijackers aboard the two airliners. After the collapse of the World Trade Center, hospital workers and law enforcement officers began referring to the World Trade Center site as "Ground Zero".

One of the first memorials was the "Tribute in Light", an installation of 88 searchlights at the footprints of the World Trade Center towers. In New York City, the World Trade Center Site Memorial Competition was held to design an appropriate memorial on the site. The winning design, "Reflecting Absence", was selected in August 2006, and consists of a pair of reflecting pools in the footprints of the towers, surrounded by a list of the victims' names in an underground memorial space. The memorial was completed on September 11, 2011; a museum also opened on site on May 21, 2014.

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.
