[A] chronicle of the civil and military aviation responses to the [9/11] hijackings that originally had been prepared by investigators for the 9/11 Commission, but never completed or released, [is about to be published]. Though some of the audio has emerged over the years, mainly through public hearings and a federal criminal trial, the ... complete document, with recordings, is being published for the first time by the Rutgers Law Review. Most of the work on the document - which commission staff members called an audio monograph" - was finished in 2004, not in time to go through a long legal review before the commission was shut down that August. At hearings in 2003 and 2004, the 9/11 Commission played some of the recordings and said civil and military controllers improvised responses to attacks they had never trained for. The account published this week is missing two essential pieces that remain restricted or classified. One is about 30 minutes of the cockpit recording of United Airlines Flight 93. The other still-secret recording is of a high-level conference call that ... grew, over the course of the morning, to include ... Mr. Cheney, Defense Secretary Donald H. Rumsfeld and the vice chairman of the Joint Chiefs of Staff, Gen. Richard B. Myers. The recording was turned over to the National Security Council. The 9/11 Commission was not permitted to keep a copy of it or of the transcript ... and investigators were closely monitored when they listened to it.
