On September 11 2001, the United States of America was attacked by what became the biggest terrorist attack in history. The attack was planned and executed by Osama bin Laden and 19 members of al Qaeda. Following the attack, a plethora of conspiracy theories began to emerge which all rejected the official explanation, and instead pointed to a secret group of powerful individuals and organizations as perpetrators. 911facts.dk investigates some of the most popular conspiracy theories and who are promoting them, based on a rational, skeptical and scientific point of view. 911facts.dk is written and edited by an independent group.

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.

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.

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.

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.

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.


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.

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.

Was the collapse of the World Trade Center due to fire or controlled demolition?
In this article, the two main arguments used to support an alternative explanation of the collapses of the World Trade Center 1, 2, and 7 are examined to see if they are logically consistent.

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.

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.
