On September 11, 2001, terrorists attacked the World Trade Center in New York City crashing commercial aircraft into the 110-story towers. The damage to the buildings caused by the aircraft impacts combined with the ensuing fires ignited by the jet crashes, led both buildings to collapse killing in all 2823 people. The death and destruction was unprecedented in the United States and the worst building disaster in human history.

The National Institute of Standards and Technology has proposed a response plan consisting of three key program elements to be conducted in parallel. These are:

The talk will describe the NIST response plan in the context of the events of September 11, 2001and the lessons expected to be derived to reduce future vulnerabilities.
