Engineers for Competency and Responsibility in the Profession

We, the undersigned engineering professionals, are satisfied that the Twin Towers of the World Trade Center collapsed due to fires following plane crashes. We affirm that it is not only possible for a steel framed office building to collapse due to fire, but that fire caused the collapse of Word Trade Center 7. We have confidence in the official engineering reports presented by NIST about the collapses of the Twin Towers and Building Seven. We have confidence in the quality of the investigation into the collapses, the integrity of the findings and the adequacy of the forensic evidence. We reject the hypotheses that any of the buildings were destroyed either by explosives or by incendiary thermitic reactions as they are not only unnecessary for collapse but poorly fit the evidence.
