Barry Mawn, director of the FBI’s New York office, sends specialized teams to the World Trade Center site after hearing Flight 11 crashing into the North Tower, even though he initially thinks the crash is an accident. Mawn is in his office on the 28th floor of 26 Federal Plaza in Lower Manhattan and has just heard the explosion when Flight 11 hit the WTC, at 8:46 a.m. (see 8:46 a.m. September 11, 2001). Kathy MacGowan, his secretary, shouted: “The World Trade! The World Trade!” Mawn now goes to her window, from where he can see smoke billowing from the North Tower. MacGowan says a commercial jet has crashed into the building. However, it supposedly does not occur to Mawn that the incident was a terrorist attack. [Kessler, 2002, pp. 1-2; CNN, 2/18/2002; Wright, 2006, pp. 357] “At that point, I thought it was an accident,” he will later recall. [Washington Post, 10/20/2001] Mawn’s colleagues look to the director for guidance. “People were turning to me and asking, ‘What are we going to do next, boss?’” Mawn will recall. Mawn instructs MacGowan to call the FBI evidence response team. Despite thinking the crash is an accident, he adds, “Just in case, call the SWAT [the FBI special weapons and tactics team] and the Joint Terrorism Task Force,” which has exclusive jurisdiction over local terrorism investigations. He tells MacGowan to send the teams to Church and Vesey Streets, and says he will head that way himself. Before he leaves his office, though, he is called by David Kelley, chief of Manhattan US Attorney Mary Jo White’s terrorism unit. [Kessler, 2002, pp. 2; Wright, 2006, pp. 357; Lawrence Eagle-Tribune, 9/10/2016] White has instructed Kelley to go to the WTC site. [New York Metro Super Lawyers, 7/2006] Mawn agrees to meet him and then goes and joins him outside his building. The two men make their way toward the WTC, which is eight blocks away from the FBI office. They stop at the corner of Church and Vesey Streets, at the northeast corner of the WTC site. There, they join Police Commissioner Bernard Kerik and other law enforcement officials. [Washington Post, 10/20/2001; Kessler, 2002, pp. 2] Mawn and Kelley will be at the WTC site when Flight 175 crashes into the South Tower, at 9:03 a.m. (see 9:03 a.m. September 11, 2001), and Mawn will then realize that the US is under attack (see After 9:03 a.m. September 11, 2001).
