A December 8, 2007 Freedom of Information Act request of the Federal Bureau of Investigation, seeking the release of all data contained by the Solid State Flight Data Recorders recovered from the crash scenes of American Airlines flight 77 and United Airlines flight 93, has been denied. The data sought, would presumably confirm the commercial flight histories and thus the federal registry identifications of N644AA (AA 77) and N591UA (UA 93), already provided by the Bureau of Transportation Statistics, obtained by a December 28, 2007 FOIA release. (See BTS release letter)The FDR data requested of the FBI, was that which would presumably reveal the identity of flights occurring just before the final 9/11 flights (presumably matching flight history data provided by the BTS, for the said aircraft), carried out by N644AA (AA 77) and N591UA (UA 93), 2 of the 4 federally registered aircraft reportedly used to carry out the terrorist attacks of September 11, 2001. An appeal indicating that the requested records are unrelated to the events of September 11, 2001 and thus cannot interfere with 9/11 enforcement proceedings (indicated in refusal notice), is pending.BTS data release statement, regarding the commercial flight history of the 4 federally registered aircraft reportedly used to carry out the terrorist attacks of September 11, 2001, during the 1 year period prior to their destructions:

From the December 8, 2007 FBI FOIA request:

“I request that copies of documentation revealing the following information, be provided to me:

- Those which reveal specific data contained within the Solid State Flight Data Recorders (SSFDRs) recovered from the crash scenes resulting from the terrorist attacks of September 11, 2001, of American Airlines flight 77 (N644AA) and United Airlines flight 93 (N591UA). The data sought is that recorded by both SSFDRs which reveals the flight data of the flights which occurred before September 11, 2001, which was also recorded by the said SSFDRs.”

Information responsive the FOIA request apparently exists, based on the FBI’s refusal to provide it.

A response from the NTSB regarding a request for the same information, has not been received.

The Solid State Flight Data Recorders contained aboard AA 77 and UA 93, recorded the final 25 hours of flight history for each given aircraft. This history presumably includes data pertaining to one or more flights in addition to those that occurred on September 11, 2001.

AA 77 SSFDR data:

The FBI has determined that the release of SSFDR data for AA 77 and UA 93 would not interfere with enforcement proceedings, yet the release of data for flights carried out by N644AA (AA 77) and N591UA (UA 93) that occurred prior to September 11, 2001, apparently contained by the same SSFDRs (that would presumably confirm flight history data provided by the BTS), is “expected to interfere with enforcement proceedings”.

According to the FBI, “the material requested is located in an investigative file which is exempt from disclosure pursuant to Title 5, United States Code, Section 552, subsection (b) (7) (A).”

To date, the U.S. federal government has failed to provide any evidence that would confirm the alleged federal registry identifications of the aircraft used to carry out the 9/11 attacks.
