Those of us who have worked closely with Wayne Coste know him to be an exceptionally keen observer of details often overlooked by others.  He is probably best known in the movement for his groundbreaking analysis of the evidence at the Pentagon, but he has done valuable work on the World Trade Center as well.

Wayne has carefully reviewed the dynamics of the Twin Towers’ destruction to propose a mechanism of destruction that adds nuance to the more general assertion that “explosives” were used.  We know that thermite was used at the World Trade Center, in some manner, because we have found evidence for thermite reactions and we have found unreacted nanothermite residues in the dust, but the forceful lateral ejection of large amounts of material during the collapse has led many to suggest that high explosives must also have been used.  While Wayne’s hypothesis doesn’t rule out the use of high explosives entirely, he has concluded that what we actually see happening during the demolition can be better understood as the effects of nanothermite “tuned to an intermediate reaction rate” pushing the columns outward rather than shattering them. In a preliminary paper he has explained this mechanism in detail as he envisions it, and provides a substantial number of observations that support this hypothesis.

The subtitle of Wayne’s main paper is “The Case for Propelled Demolition.” The origin of the term is based on a classification of energetic materials described by Niels Harrit that is based on how quickly an energetic material reacts. For example nanothermite can be “tuned” to act, on one extreme, almost like a high explosive, and on the other extreme as an incendiary, simply generating tremendous heat but without doing mechanical work.  But in between, it can be tuned to a moderately fast, but not “explosive,” reaction rate resembling a rocket propellant.  Wayne makes the case that nanothermite, in this intermediate mode, can explain the observations in the building collapses and in the rubble pile better than the assumption that high explosives were used.  The expanding gasses on each floor literally ripped the building apart.  An analysis in his follow-up paper (“Surfing the Big Wave on 9/11”) describes, in detail, a section of perimeter columns that spans the entire width of the South Tower being propelled horizontally as a single entity at ~80 ft/sec while in freefall.
