Die Besonderheiten des WTC7 unterschlägt er:
:''The probable collapse sequence that caused the global collapse of WTC 7 involved the initiation of the buckling of a critical interior column in that vicinity. … The buckling of this column led to a vertical progression of floor failures up to the roof, and led to the buckling of adjacent interior columns to the south of the critical column … This was a fire-induced progressive collapse, also known as disproportionate collapse, which is defined as the spread of local damage, from an initiating event, from element to element, eventually resulting in the collapse of an entire structure, or a disproportionately large part of it.''
