INTRODUCTION The attack on the World Trade Center (WTC) in New York City on September 11, 2001 by terrorists flying hijacked commercial aircraft into the two towers (WTC 1 and WTC 2) was among the worst building disasters in the history of the United States. In response, Congress requested that the National Institute of Standards and Technology (NIST) investigate the technical causes for the disaster. NIST publicly announced its Building and Fire Safety Investigation of the World Trade Center Disaster on August 21, 2002. On October 1, 2002, the National Construction Safety Team Act was passed by Congress, and the Investigation was carried out under the authority provided by this act.
