These 2 videos are worth every minute/second of your time. They convincingly convey that the 3 buildings of the World Trade Center collapsed as a result of what could only have been a controlled demolition with the use of a military-issue combination of nano thermite and sulphur explosives. Take a look and listen to the evidence. It is irrefutable.
None of the videos focus on some sort of conspiracy theory but rather on the fact that the NIST findings of the catastrophe were vague and misleading (a cover-up of sorts) in their conclusion that there were no explosions involved in the destruction of the 3 buildings – and particularly WTC Building #7. What is presented is ample scientific evidence that indicates the cause of the collapse of the three buildings was more akin to controlled demolitions and, as such, necessitates the need for a judicial investigation.
