There is much controversy over what happened that day, not only between those who support and those who dispute the official explanation but also among various groups within the “9/11 truth movement”. The basic purpose of this website is to examine and present soundly based scientific evidence that the buildings were brought down by “controlled demolition” using explosives. It is hoped that this will provide a clear picture by collecting together the most compelling evidence for demolition, while avoiding those aspects of 9/11 which are still in dispute.
The US administration does not admit the possibility that the towers were brought down with explosives. The government has authorized three investigations, all of which attempt to explain the collapses of the towers as due solely to the combined effects of the plane impacts and the resultant fires. None of the investigations properly examines the question of whether controlled demolition might better fit the observations.
