Rich Miles, the manager at the United Airlines System Operations Control (SOC) center just outside Chicago, receives a call from a supervisor at United’s maintenance office in San Francisco, informing him that Flight 175 has been reported as hijacked. [Wall Street Journal, 10/15/2001; 9/11 Commission, 8/26/2004, pp. 22] The maintenance office received a call minutes earlier from a flight attendant on United 175, who said their plane had been hijacked (see 8:52 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 7-8] When the supervisor tells Miles about this, he initially responds, “No, the information we’re getting is that it was an American 757.” (The FAA has just informed United Airlines that the plane that hit the World Trade Center was a hijacked American Airlines 757 (see (Shortly After 8:48 a.m.) September 11, 2001).) But the supervisor insists, “No, we got a call from a flight attendant on 175.” [Wall Street Journal, 10/15/2001] Miles notifies his boss Bill Roy, the SOC director, about this information. Roy then contacts United’s CEO Jim Goodwin and its chief operating officer Andy Studdert, who are in a meeting at the airline’s headquarters, located next to the SOC. Roy then begins the process of activating the crisis center at the United headquarters, which will take about 30 minutes to complete.
