The Port Authority of New York and New Jersey holds a drill at the World Trade Center based on the scenario of a plane crashing into one of the Twin Towers. Numerous agencies participate in the drill, which is held on a Sunday. As well as the Port Authority, these include the New York City Fire Department, the New York City Police Department, and the Emergency Medical Services. Guy Tozzoli, the director of the Port Authority’s World Trade Department, will describe the drill during a legislative hearing in 1993 (see (March 29, 1993)). He will recall that the Port Authority simulates the “total disaster” of “the airplane hitting the building” and participants simulate “blood coming out of people.” He will add that the drill is “a real preparation for a disaster.” [Newsday, 11/12/2001; Dwyer and Flynn, 2005, pp. 58-59] (During the hearing, Tozzoli will mistakenly recall the drill being conducted in the late 1970s, but it is in fact held in November 1982. [Dwyer and Flynn, 2005, pp. 274] ) The drill follows an incident in 1981, when an Argentine aircraft came within 90 seconds of crashing into the WTC’s North Tower as a result of having problems communicating with air traffic controllers (see February 20, 1981). Asked about the drill shortly after 9/11, Tozzoli will say it was held “just to have people trained within the city for that particular scenario [of a plane hitting the WTC].” The 1982 exercise appears to be the last “joint drill involving all the emergency responders” held at the WTC prior to the 9/11 attacks, 19 years later, according to New York Times reporters Jim Dwyer and Kevin Flynn.
