At the CIA’s Langley headquarters, Deputy Director for Operations James Pavitt has arrived back at his office after attending an 8:30 a.m. meeting in the agency’s conference room (see Shortly After 8:48 a.m. September 11, 2001). The second WTC tower has already been hit by this time. Pavitt sends a message to all CIA stations, saying, “I expect each station and each officer to redouble efforts of collecting intelligence on this tragedy.” Mary, the CIA’s New York station chief, calls him. In this call, Pavitt and Mary agree that Osama bin Laden is behind the attack. According to journalist and author Ronald Kessler, they believe that “Its scope, temerity, degree of planning, and viciousness fit his way of operating.” [Kessler, 2003, pp. 202-204]
