The editor of a special issue of Fire Technology invited the NIST authors to address the NIST Investigation of the WTC disaster and associated practice and research progress in the 10 years since then. The three published papers are a summary of the extensive investigation of the collapses of the WTC 1, WTC 2, and WTC 7 buildings. Professors Quintiere and Williams have a hypothesis of the WTC 1 and WTC 2 collapses that differs from the accumulated evidence and performed analyses in the NIST reports. This letter provides citations to the documentation of aspects of the Investigation that Profs. Quintere and Williams wrongly assert were not considered or were considered incorrectly in the NIST investigation. NIST stands by its findings.
