Introduction
In this paper I focus on the application of the scientific method to the study of what really happened on 9/11/2001, particularly in the destruction of the World Trade Center buildings. There is something here to look at in depth: this is serious business. It is not just “nutty fringe science” or “conspiracy theory” that can be rejected without even considering the data. There is need for scientific scrutiny as I hope to demonstrate in this paper. In fact my colleagues and I now feel that we have sufficient data to conclude that the collisions of jets with the two Towers are NOT sufficient to explain the complete and rapid collapses of both Towers and WTC 7. We conclude that the evidence is compelling that the destruction of the WTC buildings involved planted cutter charges (such as explosives and incendiaries). We will consider this evidence.
