WTC 2 collapses

On September 11, 2001 at 9.59 AM, 2 World Trade Center, South Tower, collapsed after burning for about 56 minutes because the tower''s steel columns that were damaged by the plane crashing into the tower gave in to the heat from the fire.

It is estimated that 618 people, who were over or at the place of impact or otherwise did not make it down, died as a result of the collapse, which is considerably less than in the other tower, because the authorities had started evacuating 2 WTC as they heard that 1 WTC had been hit. In addition, hundreds of rescuers died in and around the building.

The collapse of the tower also caused severe damage to the surrounding buildings, including 3 and 4 World Trade Center, as well as infrastructure such as water supply and metro stations.

Below, we investigate various conspiracy theory claims related to the collapse of the South Tower.


Black boxes found at the World Trade Center

Two rescue workers in the so-called TRAC-team (Trauma Response Assistance for Children), Nicholas DeMasi and Mike Bellone, claim that they helped FBI agents find and salvage three of the four black boxes from the planes that hit the World Trade Center 1 and 2. It is claimed that the FBI later left with the boxes. The boxes were supposedly found on October 3, 2001.



Empire State Building was hit by a plane, but did not collapse

The claim indicates that World Trade Center 1 and 2 did not collapse due to being hit by the two planes and the ensuing fires.



Ferrous spheres can only be due to thermite reaction

The claim is used to support the claim that huge quantities of explosives and top secret military-developed nanothermite were placed in the World Trade Center 1, 2, and 7 prior to September 11, 2001. When the nanothermite (and explosives) were ignited, the three buildings then collapsed.



Freefall and symmetrical collapse

The claim suggests that freefall speed and symmetry should be signs of controlled demolition, as well as the buildings should have been able to withstand the collapse of some floors due to fire. Since each building collapsed completely, it must mean that they were all destroyed by controlled demolition.



Highrises on fire have never collapsed

The claim posits that it is suspicious that the World Trade Center 1, 2 and 7 collapsed, since it would be the first time that steel-framed highrises collapsed due to fire. It is thus argued that a conspiracy consisting of the american government was behind the attack and not, as previously established, Osama bin Laden, al Qaeda, and the 19 terrorists.



Isolated explosions under the collapse front

The claim is used to support the theory that the World Trade Center 1, 2 and 7 did not collapse due to the terror attack but because many tons of explosives and nanothermite were placed in the buildings prior to the attack.



It is possible to smuggle explosives through security

An article in The Washington Post describes how, in 2009, American security agents from the Government Accountability Office (GAO) succeeded in smuggling materials for small bombs through security in ten important government buildings. The agents then put together the small bombs and walked around with them, unhindered. The article is used by the Truth Movement to support the claim that, leading up to September 11, 2001, huge quantities of explosives and top secret military-developed nanothermite were placed in the World Trade Center 1, 2, and 7. It is argued that, since agents in secret can smuggle materials for explosives into federal buildings, there is nothing that prevents the World Trade Center 1, 2, and 7 from being destroyed by controlled demolitions.



Maintenance workers placed explosives in the Twin Towers

A number of companies, among them Ace Elevators and Turner Construction, that were doing maintenance work on elevators at the World Trade Center 1 and 2 in the days before September 11, 2001 should ostensibly have been involved with placing explosives on all floors in the buildings, either by placing the explosives themselves or as a cover for someone else placing it.



NIST left out FEMA’s conclusion of melted steel

The FEMA report is claimed to mention melted steel, which according to the Truth Movement is regarded as evidence that the so-called nanothermite was used to instantaneously melt supporting steel elements in the World Trade Center 7 as part of a controlled demolition.



Poul Nyrup Rasmussen knew it would happen

The claim refers to a documentary on the Danish National Broadcasting Company, channel DR2, where Poul Nyrup Rasmussen, who was Prime Minister of Denmark on September 11, 2001, should have stated that he knew that the first tower would collapse before it happened. The claim is used to support the conspiracy theory that powerful people knew in advance that the terror attack on September 11, 2001, would happen, and that the World Trade Center 1, 2, and 7 would collapse, because there had supposedly been placed many tons of nanothermite and explosives in the buildings.



Pulverized concrete and fragmented steel

The claim points to the World Trade Center 1, 2, and 7 having been destroyed by tons of nanothermite and explosives placed on all or most floors.



Signs of explosives in FEMA report

The claim refers to a report by FEMA. The scope of the terror attack resulted in FEMA being tasked to conduct a number of investigations of the events on September 11, 2001. The results of these investigations were published in a report in May 2002. It is claimed that the FEMA report’s steel analyses show sulfidation, oxidation, and intergranular melting, which are signs of explosives.



Steel sections fly horizontally with more than 180 km/h

It is claimed that the World Trade Center 1 and 2 didn’t collapse due to fires and structural damages from the impacts of the hijacked passenger planes. Instead, explosives were placed in the buildings and later detonated, causing them to collapse. Steel sections, weighing many tons, being ejected with enormous force from the buildings should thus be evidence of how powerful these explosives were.



Sudden collapse

The collapses of the World Trade Center 1, 2, and 7 are claimed to have happened instantaneously and quite surprisingly. This is considered evidence that the buildings were destroyed by explosives.



Symmetrical dust clouds are signs of controlled demolitions

Unnatural symmetrical formation of dust clouds of building parts is seen as evidence that the World Trade Center 1, 2, and 7 did not collapse as described in the official reports, but were destroyed by controlled demolitions triggered by remote control.



The fires did not cause building collapses

The final report from NIST on World Trade Center 1 and 2 concludes that the towers would not have collapsed if it hadn’t been for the missing fire insulation. The Truth Movement then claims that “no steel-framed high-rises have collapsed by fire alone.”



The report about the towers does not include the collapse

The claim was made by the Danish chemistry professor emeritus Niels Harrit during the radio show DR Detektor on the Danish Broadcasting Corporation on March 9, 2011. Niels Harrit claimed that the National Institute of Standards and Technology (NIST) has not included the collapses of the World Trade Center 1 and 2. Niels Harrit also claimed on the show that the buildings were destroyed by explosives. Niels Harrit repeated the claim on the radio show Wiretapped on the Danish radio station Radio 24syv. The claim is used to demand a new investigation of the events on September 11, 2001.



There were two planes, but three buildings that collapsed

The claim is used to support the claim that the Twin Towers did not collapse due to the damage caused by the planes, and the subsequent planes, and furthermore, that the collapse of the towers showed clear signs of controlled demolitions, where demolition experts have placed explosives strategically in the buildings’ structure. At a certain time, the explosives are detonated, destroying the buildings, with as little damage to the surrounding buildings as possible.



Thermite found in the dust from the World Trade Center

The claim stems from a video clip by the World Trade Center 2 shortly before the building collapses. Glowing material can be seen coming out of the building. This was quickly seen by conspiracy theorists led by physicist Steven Jones as a result of ignited thermite. It was claimed that the material was melted iron/steel.



The ruins at Ground Zero did not fit with FEMA’s explanation

FEMA’s premilinary explanation of the collapses was that the fires probably caused the floor beams to fail, which could have caused the floors to fall like a stack of pancakes, thereby crushing the buildings. The claim insinuates that, since FEMA’s explanation does not reflect the real conditions, something suspicious must be going on.



The third explosion brought down the tower

The claim stems from a Youtube clip of a live television broadcast from the American WCBS. Thomas Torrent from the Danish Truth Movement published on July 19th, 2012 a link to the clip with the headline “The third explosion brought down the tower”. The clip was not accompanied with any comment.



Tons of melted metal at Ground Zero

The claim posits that melted metal/iron is equivalent to the World Trade Center 1, 2 and 7 being destroyed by nanothermite which should have melted tons of metal and helped cause the building collapses.



Volcanic-like dust clouds

The claim could mean that the dust clouds from the collapsing World Trade Center are evidence that the buildings were brought down by explosives. The claim could also mean that the dust clouds were so hot that they were pyroclastic clouds.



Witnesses saw explosions and flashes of light

The claim is based on interviews with people on the streets near the World Trade Center on September 11, 2001. These people have heard explosions of some kind. The Truth Movement uses this claim to support the conspiracy theory that the World Trade Center 1, 2, and 7 were destroyed with nanothermite and explosives.



World Trade Center 1, 2, and 7 fell in their own footprints

Niels Harrit, a Danish retired chemistry professor, hints in his lecture about the terror attack on September 11, 2001, that the buildings ought to have toppled like certain buildings have done after their foundations had been damaged due to e.g. earthquakes or mudslides. His argument for an alternative explanation is that, since the World Trade Center 1, 2, and 7’s foundations were not damaged, it must be evidence that the official account is false.
