FAA report, Summary of Air Traffic Hijack Events: September 11, 2001, Sept. 17, 2001 [Referenced Chapter 1, The 9/11 Commission Report, "We Have Some Planes," footnote 44]

The most comprehensive chronology of the hijackings released by the FAA in this series, this report contains factual records, observations from FAA officials and general official commentary seeking to better explain events. Remarking on United Flight 175, the report observes, "The controller communicating with UL175 was also monitoring the flight track of AAL11. Based on coordination received from ZBW [Boston Air Route Traffic Control Center] indicating a possible highjack, most of the controller's attention was focused on AAL11." Although difficult to read due to the poor quality of the document, the report also contains radar diagrams of the planes and a useful summary chart of all four hijacked flights that provides an overview of events as they unfolded.
