The National Security Archive Electronic Briefing Book series has intrigued and informed policymakers, students, and the general public for the past few years. This latest release should be no different as it provides FAA documents that deal with the attacks on the United States that occurred on the morning of September 11, 2001. These particular documents were referenced extensively in the first chapter of The 9/11 Commission Report and help corroborate the observation that the FAA was under prepared as it attempted to deal with these coordinated attacks. This particular collection includes eight documents, including radar reports and extensive chronologies that track the broader response of the US government in the wake of the attacks until late October 2001. Some of the more compelling materials include the FAA report titled “Summary of Air Traffic Hijack Events: September 11, 2001” which provides the most comprehensive chronology of the events of that day.
