Length: 15 pages

On September 11, 2001, terrorists flew two hijacked commercial airplanes into the twin towers of the World Trade Center in New York City. The north and south towers collapsed killing some 2,800 people and causing over $50 billion in property damage.

National Institute of Standards and Technology (NIST) conducted an investigation into the disaster. Final report of the investigation was issued on October 26, 2005; it consists of 43 documents totaling some 10,000 pages. This course summarizes the key findings relating to structural engineering from those 43 documents and some related background materials from other reports.
