(9:30 a.m.) September 11, 2001: Office of Emergency Management Command Center Is Evacuated; Exact Time Is Unclear

[Source: Publicity photo]The headquarters of New York’s Office of Emergency Management (OEM), which is on the 23rd floor of WTC Building 7, is evacuated at approximately 9:30 a.m., according to the 9/11 Commission. The headquarters was opened in 1999 and was specifically intended to coordinate the city’s response to disasters such as terrorist attacks (see June 8, 1999). A senior OEM official orders the evacuation after being told by a Secret Service agent that additional commercial planes are unaccounted for (see (9:30 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 283-284 and 305] OEM personnel do not initially respond to the evacuation order with a sense of urgency. According to a 2003 report by the Mineta Transportation Institute, “They calmly collected personal belongings and began removing OEM records, but they were urged to abandon everything and leave the building quickly.” [Jenkins and Edwards-Winslow, 9/2003, pp. 16] However, there are contradictory accounts of when the OEM command center is evacuated. The National Institute of Standards of Technology (NIST) claims the evacuation happens slightly later than stated by the 9/11 Commission, at “approximately 9:44 a.m.” [National Institute of Standards and Technology, 9/2005, pp. 109 ] Other accounts suggest it may have happened before 9:03, when the second attack occurred (see (Soon After 8:46 a.m.-9:35 a.m.) September 11, 2001 and (Shortly Before 9:03 a.m.) September 11, 2001). Fire Commissioner Thomas Von Essen will arrive at WTC 7 shortly before the collapse of the South Tower, looking for Mayor Giuliani. Learning that the OEM headquarters has been evacuated, he later claims that he thinks, “How ridiculous. We’ve got a thirteen-million-dollar command center and we can’t even use it.” [Essen, 2002, pp. 26] He says in frustration, “How can we be evacuating OEM? We really need it now.” He will later tell an interviewer that he’d headed for the OEM headquarters because, “I thought that was where we should all be because that’s what [it] was built for.” [Fink and Mathias, 2002, pp. 230] All civilians were evacuated from WTC 7 earlier on, around the time the second WTC tower was hit (see (9:03 a.m.) September 11, 2001).
