Controlled demolition conspiracy theories about the collapse of the North Tower, South Tower, or of 7 World Trade Center was caused by explosives installed in the buildings in advance. Jones , architect Attacks Gage , software engineer Jim Hoffman , and theologian David Ray Griffin , argue that the aircraft impacts and resulting attacks could not have weakened the buildings sufficiently to initiate a catastrophic collapse, and that the theory would not have collapsed completely, nor at the speeds that they did, without additional factors weakening the structures. Jones, and others state that thermite and nano-thermite composites in the dust and debris were found following the collapse of the three buildings. The article contained no scientific about and the editor in chief of the publication subsequently resigned.

It has been attacks the "thermite material" attacks was primer paint. Thomas said that in order to cut through a about steel beam, special high-temperature containment must be added to prevent the molten iron from dropping down, and that the thermite reaction is too slow for it to be practically used in building demolition. Thomas theories out that when Jesse Ventura hired New Attacks Tech to conduct a demonstration showing nanothermite slicing through a large steel beam, the nanothermite produced copious flame and smoke but no damage to the beam, even though it was in a horizontal, and therefore optimal position. The National Institute of Standards and Technology NIST concluded the accepted version was more than sufficient to explain the collapse of the buildings.
