Washington, DC - August 11, 2006 - 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.

In late 2001 and early 2002, the National Transportation Safety Board (NTSB) filed reports detailing information of the four commandeered flights, based on a combination of air traffic control recordings and, in the case of United Flight 93, the plane's flight data recorder. However, these reports remained hidden from public view for years. Even today, the entries in the NTSB database for the 9/11/2001 crashes state:
The terrorist attacks of September 11, 2001 are under the jurisdiction of the Federal Bureau of Investigation. The Safety Board provided requested technical assistance to the FBI, and this material generated by the NTSB is under the control of the FBI. The Safety Board does not plan to issue a report or open a public docket
The veil was lifted from the reports on August 11, 2006 when they were published by the National Security Archive on the George Washington University website, gwu.edu. The release consists of eight PDF documents listed on the National Security Archive Electronic Briefing Book No. 196.

NTSB: 'We do not plan to issue reports on 9/11 flights' - Democratic Underground
S0 it appears that as has been stated the NTSB in the case of flight 93 did their investigation and turned over their findings to the FBI. Stack is a different case and not one I have studied. Nor do I see where what was done there is relevant to 2001.
Fact 1 : The FBI was in charge of the investigations on 911. (why is immaterial)
Fact 2 : The FBI called in various agencies to assist in their areas of expertise, NTSB is one of those. FDNY would be another, New york port authority would be yet another, And the list goes on.
Fact 3 : These agencies submitted their individual reports to the FBI.
Fact 4 : It's not rocket science.
