Commerce’s NIST To Hold WTC Press Briefing In New York

Gaithersburg, MD – The Commerce Department’s National Institute of Standards and Technology (NIST) will hold a press briefing to issue a detailed interim report on the progress of its technical building and fire safety investigation of the World Trade Center (WTC) disaster following the terrorist attacks of Sept. 11, 2001.

WTC Lead Investigator Shyam Sunder will summarize and answer questions on the report, including highlights such as:

  • interim findings and accomplishments;
  • working hypotheses for the collapse of the WTC towers and WTC-7;
  • key visual observations on the building, fire and smoke conditions in all three WTC buildings derived from the analysis of collected still and video images;
  • development of computer simulations to model the most probable collapse sequence for the WTC towers and WTC-7;
  • progress in experimental/field work (including the analysis of recovered WTC steel and fire tests); and
  • early results from the analysis of first-person interviews of nearly 1,200 WTC occupants, first responders and families of victims.

Following the briefing, the full report will be available on the NIST WTC investigation Web site,
