A New York Times article theorizes that diesel fuel tanks were responsible for the collapse of Building 7 of the WTC. It collapsed at 5:20 p.m. on 9/11, even though it was farther away from the Twin Towers than many other buildings that remained standing (see (5:20 p.m.) September 11, 2001). It was the first time a steel-reinforced high-rise in the US had ever collapsed in a fire. One of the fuel tanks had been installed in 1999 (see June 8, 1999) as part of a new “Command Center” for Mayor Rudolph Giuliani. [New York Times, 3/2/2002; Dow Jones Business News, 9/10/2002] However, in interviews, several Fire Department officers who were on the scene say they were not aware of any combustible liquid pool fires in WTC 7. [Fire Engineering, 9/2002] And, according to the National Institute of Standards and Technology (NIST), between 11:30 a.m. and 2:30 p.m. on 9/11, “No diesel smells [were] reported from the exterior, stairwells, or lobby areas” of WTC 7. [National Institute of Standards and Technology, 6/2004, pp. L-22] Curiously, given all the Wall Street scandals later in the year, Building 7 housed the SEC files related to numerous Wall Street investigations, as well as other federal investigative files. All the files for approximately 3,000 to 4,000 SEC cases were destroyed. Some were backed up in other places, but many were not, especially those classified as confidential. [New York Law Journal, 9/17/2001] Lost files include documents that could show the relationship between Citigroup and the WorldCom bankruptcy. [Street, 8/9/2002] The Equal Employment Opportunity Commission estimates over 10,000 cases will be affected. [New York Law Journal, 9/14/2001] The Secret Service had its largest field office, with more than 200 employees, in WTC 7 and also lost investigative files. Says one agent: “All the evidence that we stored at 7 World Trade, in all our cases, went down with the building.” [Tech TV, 7/23/2002] The IRS and Department of Defense were also tenants, along with the CIA, which, it has been revealed, had a secret office in Building 7. [CNN, 11/4/2001; New York Times, 11/4/2001; Federal Emergency Management Agency, 5/1/2002, pp. 5-2; New York Magazine, 3/20/2006] A few days later, the head of the WTC collapse investigation says he “would possibly consider examining” the collapse of Building 7, but by this time all the rubble has already been removed and destroyed.
