According to a soldier at the scene, WTC Building 7 is evacuated before the second tower is hit. [Fort Detrick Standard, 10/18/2001] The National Institute of Standards and Technology (NIST) states, “As the second aircraft struck WTC 2, a decision was made to evacuate WTC 7.” This would be just after the Port Authority Police Department called for the evacuation of the entire WTC complex (see 8:59 a.m.-9:02 a.m. September 11, 2001). But by this time, “many WTC 7 occupants [have] already left the building and others [have] begun a self-evacuation of the building.” [National Institute of Standards and Technology, 9/2005, pp. 109] All individuals in the Secret Service’s New York field office, located in WTC 7, were ordered to evacuate after the first attack, and they are in the process of doing so when the second plane hits the South Tower. [PCCW Newsletter, 3/2006] The Secret Service has a Stinger missile secretly stored in the WTC, to be used to protect the president if there were an attack on the city when he visits it. [Weiss, 2003, pp. 379] Presumably, this missile is abandoned with the evacuation. The Office of Emergency Management’s command center, on the 23rd floor of WTC 7, is not evacuated until later, at 9:30 a.m. (see (9:30 a.m.) September 11, 2001).
