July 1985: Report Outlines Terrorism Threat to WTC

While the Office of Special Planning is still working on its report about the vulnerability of the World Trade Center to terrorist attack, the New York Port Authority hired security consultant Charles Schnabolk to also review the center’s security systems. [UExpress (.com), 10/12/2001; New York County Supreme Court, 1/20/2004] Schnabolk was involved in designing the original security system when the WTC complex was built. [Institue for Design Professionals, 2009; The Security Design Group, 2010] This month his secret report, titled “Terrorism Threat Perspective and Proposed Response for the World Trade Center” is released. It sets out four levels of possible terrorism against the center, and gives examples of each: ”(1) PREDICTABLE—Bomb threats; (2) PROBABLE—Bombing attempts, computer crime; (3) POSSIBLE—Hostage taking; (4) CATASTROPHIC—Aerial bombing, chemical agents in water supply or air conditioning (caused by agents of a foreign government or a programmed suicide).” Similar to other reports in the mid-1980s, it also warns that the WTC “is highly vulnerable through the parking lot.” [UExpress (.com), 10/12/2001; New York County Supreme Court, 1/20/2004]
