A "controlled demolition" looks like a controlled demolition because it is one.
Therefore, it should not be too difficult for an expert in controlled demolition to recognize one.
A "deceptive controlled demolition" is done in a way so that it does not look like a conventional controlled demolition.
Consequently, the goal is to mislead people--perhaps even controlled demolition experts.
Other demolition experts agree that demolitions took place. The ones who are on record are here:
http://demolitionexpertsquestion911.blogspot.com/ I know of others.
Under no circumstances are the laws of physics suspended--regardless of whether or not some sort of demolition was done.
NIST is not seriously investigating the possibility of the controlled demolition and deceptive controlled demolition hypotheses for WTC7 and the Twin Towers.
At the same time, NIST itself says that it has no explanation for the total collapse of the Twin Towers. In a letter dated September 27, 2007, NIST stated: "[W]e are unable to provide a full explanation of the total collapse."
NIST's reiterates this from their Twin Towers report (2005): "NIST has stated that it found no corroborating evidence to suggest that explosives were used to bring down the buildings." The next sentence admits, however: "NIST did not conduct tests for explosive residue..."
Since NIST does not have an explanation and is not investigating the possibility of explosives, perhaps the explanation they do not seriously consider is viable. That is exactly what Dr. Steven Jones and others are doing.
