Almost five years after September 11th, 2001:
"The National Transportation Safety Board (NTSB) this week released full transcripts of the air traffic control recordings from the four flights hijacked on September 11, 2001, and meticulous Flight Path Studies for three of the flights, in response to a Freedom of Information request by the National Security Archive. The studies provide the most detailed technical information available to date related to the hijackings, and the transcripts of the aircraft-to-ground communications are the first complete government disclosure of each flight's air traffic control recordings".
