100 tons, that’s quite a lot, isn’t it?

On March 3, 2015, interviewed physicist Per Hedegaard about his involvement in the court case filed by Niels Harrit against Danish newspaper Weekendavisen. A U.S. website had claimed that Per Hedegaard had changed his mind and would testify in support of...

4,000 Israelis did not show up for work

This claim is rooted in the myth that Jews are, and have been, behind the largest conspiracies throughout time. When that many Jews don’t show up for work, it must be because they were warned beforehand, as opposed to non-Jews, who then became victims of the terror attack.

Analysis of a petition:

This article takes a closer look at one of the numerous petitions started by the Truth Movement following the terror attack on September 11, 2001. The object is to ensure what the movement calls an “independent investigation” of the events on that day.

Analysis: "The Official Video: ReThink911 September 2013"

In July 2013 the umbrella organization ReThink911.org0 which comprises of a number of groups within the Truth Movement a video asking for financial support for an information campaign. The goal is to get the public to realize that the official explanation of the...

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.

Bush ignored warnings about an attack

The many warnings should have been ignored deliberately by the American govenment, because it wanted to pass legislation that removed civil rights, so that the overall plan for the New World Order could be implemented more easily.

CIA ordered visas for 15 of the hijackers

J. Michael Springman is a former employee at the American Consulate in Jeddah, Saudi-Arabia. During an interview with radio host Alex Jones, he claimed that, despite him refusing to grant 15 of the 19 hijackers visas for the United States, because they were on a watchlist, the CIA ordered him to grant the visas anyway.

Dancing Israelis knew the terror attack would happen

Five men, with Middle Eastern looks, were seen cheering on top of a truck while they were filming the terror attack. The men were arrested but later released from custody. When interviewed on Israeli television, they said that they were only there to film the event. The claim is used to argue that the Israeli intelligence agency, Mossad, knew in advance that the terror attack would happen.

Danish physicist supports Niels Harrit

In the time leading up to Niels Harrit’s libel trial in the High Court, a claim emerged that the former colleague of Harrit’s, physicist Per Hedegaard, had changed his mind from thinking that Niels Harrit’s theories were “crazy” to supporting Niels Harrit.

Debate-lecture with Jeppe Severin

On November 26, 2012, we held a debate with Jeppe Severin who represented the Truth Movement’s demand for a so-called new independent investigation of the terror attack on September 11, 2001. The debate took place at Kulturhuset Indre By in Copenhagen. The debate...

Debate-lecture with Niels Harrit

On October 19, 2011, we held a debate with retired chemistry professor Niels Harrit at the local cultural center, Prismen, Copenhagen, Denmark. The lecture was recorded by both our camera crew and Niels Harrit’s camera crew.We would love to bring the lecture in its...

Flight 175 could not fly 950 km/h

The claim is based on the assumption that Flight 175, a Boeing 767-222, was not designed to fly as fast as it did, when it hit the World Trade Center 2. Additionally, it was not possible to control the plane, so that it could hit the building. Thus, it cannot be Flight 175 that hit the World Trade Center 2.

Flight 77 could not fly fast close to the ground

Due to the so-called ground effect, it should not be possible for a Boeing 757 to fly close to the ground at a speed of 500 mph (800 km/h). The consequence of the claim is thus that something other than Flight 77, a Boeing 757, hit the Pentagon after having flown the last part of the stretch at 529 mph (852 km/h) a few meters above the ground.

Flight 77’s route was suspicious

The claim is used to support the claim that Flight 77 was not flown by one of the hijackers, Hani Hanjour, because the maneuver was supposedly too complicated for an untrained pilot. The claim is thus used to support the claim that Flight 77 was remotely controlled, which again should point to someone other than al Qaeda being involved in the terror attack on September 11, 2001. Instead, the attack was a so-called “inside job”. The claim leads to yet another claim: That it wasn’t even Flight 77 that hit the Pentagon but a Global Hawk drone.

Flight 93 was abducted

The claim is based on a brief article from September 11, 2001 published around noon, local time. The mayor of Cleveland, Ohio, Michael R. White, was quoted saying that a Boeing 767 from Boston had made an emergency landing in Cleveland Hopkins International Airport because it was believed there was a bomb on board.

Flight 93 was shot down

The claim that Flight 93 was shot down is based on debris from the plane being found up to 12 kilometers from the crash site. One piece of debris was a plane engine, weighing a ton, about 800 meters from the crash site. The claim is supported with the argument that the crash site does not look like a plane crash site. There are too few and too small pieces of debris. For comparison, other, even violent, crash sites are used, where easily recognizable plane parts were found.

Heavy rain points to nano-thermite

The claim, made by e.g. Niels Harrit, is used to support a central claim, namely 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. Allegedly, the nanothermite melted the metal in the buildings leaving lakes of melted metal on Ground Zero where the buildings collapsed. The claim suggests that the amounts of melted metal were so large that even heavy rain could not cool them down. It is suggested that something caused this heat to last and that this could only be nanothermite.

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.

How much support does the Truth Movement have?

It is inherently difficult to establish precisly how much public support exists for the Truth Movement. Polls can give some indication of a mood in the population but the polls that are used by the Truth Movement (and usually paid by same) rarely says anything about...

How to “expose a cover-up”

Despite innumerable claims of solid evidence of the existence of the New World Order, it always turns out that the evidence is of more or less doubtful nature. One such example is this “exposure” from June 13, 2011, published on the blog 0: The main...

Impossible to identify the terrorists from DNA

Allegedly, it should be implausible that any human tissue or bone material would survive the massive destruction. It would also be impossible to compare surviving DNA with DNA from the terrorists, since they had not given DNA samples to the authorities before the terror attack. Furthermore, the claim suggests that there weren’t any hijackers on board the four planes, which means that the planes must have been remotely controlled or that the planes must have been flown into their targets by the airline pilots.

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.

Larry Silverstein committed insurance fraud

Larry Silverstein leased and insured against terror attacks from planes in the weeks before 9/11. Thus, he ordered that the World Trade Center 7 should be blown up so that he could make money from insurance fraud. The insurance sum is claimed to be $5.4 billion.

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.

No photos of Osama bin Laden’s body

The claim is used to support the conspiracy theory that Osama bin Laden was not behind the terror attack on September 11, 2001. Instead, it is claimed that Osama bin Laden died at an earlier time, in December 2001, which means that he could not have been killed by U.S. special forces on May 2nd, 2011.

No plane hit the Pentagon

The claim points to something else than Flight 77 hitting the Pentagon, which would mean that the terror attack was not carried out by Islamic terrorists.

One of the passengers saw a gun

The claim indicates that the official account is false since that states that the terrorists used box cutters. The official account should thus seek to conceal that it wasn’t untrained al Qaeda terrorists but instead trained people who were hijacking the plane.

Osama bin Laden did not die on May 2, 2011

Some believe that Osama bin Laden is not dead at all, some believe that he died in December 2001 from a lung disease and lies buried in Afghanistan, some believe he is kept frozen somewhere in the United States.

Osama bin Laden’s confession videos are faked

The Truth Movement claims that those proclamations where Osama bin Laden admits responsibility on behalf of his organization are faked. A video that appeared in December 2001 is pointed out as perhaps the most obvious evidence of a hoax.

Osama bin Laden was not wanted by the FBI for 9/11

The claim circulated primarily among conspiracy theorists prior to the liquidation of Osama bin Laden on May 2nd, 2011, by American elite forces. It was argued that, since the FBI did not specifically write on the warrant that Osama bin Laden was wanted for the terror attack on September 11, 2001, it must mean that Osama bin Laden had nothing to do with the attack.

Passenger manifests are not evidence of the persons having been on board

Jeppe Severin, representative and spokesperson for the Danish Truth Movement, claims that there is no evidence that Mohammed Atta, Marwan al-Shehhi, and Hani Hanjour, who the forensic investigation named as three of the suicide pilots, were on the three planes Flight 11, Flight 175, and Flight 77. Since those three terrorists from al Qaeda appeared on the passenger manifests for the three planes, it must mean that passenger manifests are not evidence that the persons have been on board.

Plane engine is not from Flight 175

The prominent member of the Danish chapter of the Truth Movement, Jeppe Severin, concludes unambigously that the crashed engine on Murray Street is a Pratt & Wittney JT9D-7A -7F or -7J, and not a Pratt & Wittney JT9D-7RD4, which would normally be the one Flight 175 would be equipped with.

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.

Power cut concealed placement of explosives

The claim is taken from a flyer handed out by the Danish Truth Movement and points to a conspiracy having faked a widespread power cut in order to be able to send a lot of people into the buildings to place explosives without being caught.

Rumsfeld admitted that the Pentagon was missing 2.3 trillion dollars

The claim supports the conspiracy theory that the terror attack against the Pentagon was supposedly a so-called false flag operation. Rumsfeld had knowledge that the terror attack would take place the next day, knowing that the news of the missing trillions would be buried in the massive media cover of the attack. The hijacked Flight 77 was intended to impact the Pentagon at the exact spot where the documents that would reveal the fraud would be. The impact and the subsequent damage and fires were then to destroy the evidence. The claim is also used to explain where the money to wage war in Iraq and Afghanistan came from.

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.

Stock exchange speculation

The claim is used to support the overall claim by conspiracy theorists of a world-wide secret organization which not only plans and carries out terror attacks and wars but also profits from them.

The asbestos dust from Ground Zero was declared safe

The claim insinuates that someone is trying to hide that the buildings contained so much asbestos that the cost of removing it would exceed the value of the buildings. It was therefore decided to blow up the buildings and later cover up the subsequent health risks.

The audio file with Betty Ong has been edited

The hijacked planes could have been intercepted by military planes

In 1999, Air Traffic Control lost contact with a Learjet 35 on its way from Orlando, Florida, to Dallas, Texas. On board were two pilots and four passengers, one being the famous golf player Payne Stewart. An F-16 from Eglin Air Force Base, Florida, which happened to be in the area, was dispatched to localize the plane but was unable to make contact. Two more planes were dispatched, also to make contact, but this was also in vain. The Learjet continued its course until it ran out of fuel, after which it crashed. This incident is used to argue that the hijacked planes on September 11, 2001 were intentionally not intercepted by military planes.

The Manhattan Project

The official account is a conspiracy theory

Claim The official account is a conspiracy theory0. Background The story about the 19 terrorists from al Qaeda, who hijacked four planes and where three succeeded in hitting three of their intented targets, is considered a much less credible explanation than the main...

The official account is self-contradicting

Claim Proponents of the official account claim on one hand that it required a lot of explosives to get the World Trade Center 1 and 2 to collapse and on the other that the collapse could only happen due to the plane impacts.0 Background The claim was made by Brian...

The passport in the ruins

A passport, belonging to Satam al-Suqami, one of the terrorists on bord Flight 11, was found moments before the World Trade Center 2 (South Tower) collapsed and given to a detective from the NYPD. The passport must therefore be planted.

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.

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.

The top of the World Trade Center 1 was destroyed before the collapse

The claim is used to support the overall claim that the Twin Towers did not collapse as described in the official reports, namely due to the damages from the planes and the subsequent large fires that could not be fought. Instead, the Twin Towers were allegedly destroyed by huge quantities of explosives and top secret military-developed nanothermite which 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.

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.

We are just asking questions

Those who believe that the terror attack on September 11, 2001, in reality was planned by a conspiracy within the American government often defend themselves with the phrase “we are only asking questions”, thus indicating innocence, healthy skepticism and an excuse from coming up with plausible counter-explanations. However, asking a question without explaining yourself is often in itself an indirect claim, since a question can be subjectively related to the topic and the context in which the question is asked. This is precisely the technique that the conspiracy theorists use.

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.
