The argument is mainly supported by historical examples of structural failures and the subsequent investigations. The post incident investigation tactics, or lack thereof, discussed support the argument that disasters require an existing structure for authority and procedure. The 1814 Burning of the Capitol Building is an example of an unrestricted investigation that had a successful ending, the building was reconstructed. The 1850 Hauge St. Explosion shows how a joint investigative team without proper distribution of expertise and responsibility leads to an incomplete investigation.  Finally, the 1903 Iroquois Theater Fire is an example of a modern investigation process that utilized available knowledge and resources effectively.

The bibliography shows this article was written with a significant amount of historical research into both the incidents discussed and also the materials and technical findings of the investigations.

The World Trade Center collapse was a unique disaster for American organizations to deal with, the aftermath and subsequent investigation into the collapse shows a need for a unified system of authority between investigative organizations. The paper shows the development of his system using several other disasters throughout American history.

This article has been referenced in several articles, although due to the number of scientific articles written about the World Trade Center Collapse there are likely more. One such article is “Dealing with Disaster: The Politics of Catastrophe in the United States, 1789-1861”.

Scott Gabriel Knowles is an expert in disaster and risk, he has written several papers and books on the cause of disasters and the risks found in the modern industrial era. He currently works as a professor at Drexel university and is a member of the Fukushima Forum collaborative research community.

Emergency response is not addressed in terms of the immediate response. The article focuses instead on the aftermath of the incident on Sept. 11th, dealing primarily with the cleanup efforts and investigation that followed in an effort to provide closure to the public and resume the regular business of the city, both important steps in recovering from a disaster.

Several historical examples are used including the burning of the US Capital in 1814, the Hague St. explosion in 1850, and the Iroquois theater fire in 1903. The article uses examples that were in the public awareness at the time of the disaster in order to exemplify the many agents pressuring investigators to make a rapid and acceptable decision including the public, the government, and the businesses effected.

“the demands placed on an investigation have as much, or more, to do with defining the dominant investigator and quickly addressing the fears and anger of the press, government, and an outraged public than they do with discovering the definitive technical truths of a catastrophic event.” (Knowles 11)

“The Hague Street inquest featured many experts, none with the authority to effect real change. The result was a blanket of blame that covered everyone” (Knowles 19)

“With the exception of federal oversight, Iroqouis set the tone for investigations of modern disasters from the Baltimore Conflagration (1904) to the world Trade Center collapse.” (Knowles 24)

I looked into Underwriter Laboratories, as the work that they do is both interesting and important in mitigating future disasters.

The article did not give a definitive answer as to the decided cause of the towers collapse, so I researched the prominent theories. There still exists some controversy on the subject but it is largely believed that a combination of the direction the plane faced upon impact, which allowed the keel beam to destroy several support columns of the building, and the heat form the fire causing thermal expansion of the remaining steel reinforcements, overtaxed the supports which led to a systematic failure of supports on each lower floor.

Finally, I looked at the legal changes after 9/11 to see if there were any laws put into place defining the responsibility and authority of government agencies in the aftermath of a disaster. The laws passed directly in response to 9/11 however only seem to be relating to search, seizure, and detention of suspected terrorists.
