(After 8:46 a.m.) September 11, 2001: United Airlines Control Center Experiences Communication Problems for Two Hours

Ed Soliday.Ed Soliday. [Source: Ed Soliday]Those at United Airlines’ System Operations Control (SOC) center, near Chicago, have serious problems communicating with others outside their building, particularly using e-mail, for a period of about two hours. This is according to Ed Soliday, United Airlines’ vice president of safety and security, who is involved with the airline’s response to the terrorist attacks after arriving at the SOC at around 9:35 a.m. Soliday will tell the 9/11 Commission that, on this day, United Airlines “lost e-mail capability and some of their phone and cell service.” This, he will say, is “because everyone was on the phone trying to ‘call their best friend’ to talk about what was happening,” presumably meaning that the national telecommunications infrastructure has become overloaded due to increased traffic. Soliday will add, “For a couple of hours, trying to communicate out of the [SOC] building was impossible.” [9/11 Commission, 11/21/2003 pdf file] Soliday apparently does not state the particular time period over which United Airlines experiences these communication problems. However, it appears they may begin around the time of the first attack, since, according to the 9/11 Commission, shortly before 9:00 a.m., a United dispatch manager is unable to reach top company officials because the airline’s pager system “was not working” (see (Shortly After 8:48 a.m.) September 11, 2001).
