Bill Halleck, an American Airlines air traffic control specialist at the airline’s System Operations Control (SOC) in Fort Worth, Texas, phones an official at the FAA’s Herndon Command Center, to ask about the status of New York City air traffic. During their two-and-a-half minute conversation, Halleck says American thinks Flight 11 crashed into the WTC, and says that Flight 77 is “missing.” Presently, he receives an update from someone else at SOC, indicating that Flight 77 may also have crashed into the WTC (see 9:08 a.m. September 11, 2001). He wonders how it could have gotten to New York, but updates the FAA official on this news. The FAA official replies that the second WTC crash may not have been Flight 77 because “we have another call sign” for that incident. The FAA Command Center is currently uncertain of the identity of either of the planes that hit the Twin Towers, and provides no further information. [9/11 Commission, 8/26/2004, pp. 31 and 94]
