FBI Refuses To Confirm Identity Of 9/11 Planes

FOIA Appeal Denied: FBI Again Refuses To Confirm Identity Of 9/11 Planes

In an effort to end speculation surrounding the events at the Pentagon building on September 11, 2001, a Freedom of Information Act request was made of the Federal Bureau of Investigation, seeking confirmation of the process by which recovered debris belonging to the 4 aircraft used in the 9/11 terrorist attacks was identified. This request was denied. An appeal of that decision has also been denied. Court action is pending.

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).”

This subsection reads: “could be reasonably be expected to interfere with enforcement proceedings.”

The FBI has publicly declared that certain civil aircraft were involved in the terrorist attacks of September 11, 2001. It apparently was not believed by the FBI, that disclosure of that information would jeopardize any September 11th “enforcement proceedings”.

It is unknown why disclosure of aircraft identifying data – that is presumably the basis for the FBI’s current public opinion regarding the 9/11 planes and which was likely provided by the Federal Aviation Administration or the National Transportation Safety Board – could then jeopardize FBI “enforcement proceedings”.

“The National Transportation Safety Board is an independent Federal agency charged by Congress with investigating every civil aviation accident in the United States.”


The NTSB acknowledges that it provided assistance to the FBI, regarding its investigation of the civil aircraft reportedly used during the terrorist attacks of September 11, 2001:

“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 any material generated by the NTSB is under the control of the FBI.”

The FBI currently lists American Airlines flight 11, United Airlines flight 175, American Airlines flight 77 and United Airlines flight 93, as those used to carry out the 9/11 attacks:


The National Transportation Safety Board lists the above flights on September 11, 2001 as being provided by the following aircraft, that were listed under the Federal Aviation Administration registry as follows:

American Airlines flight 11 – N334AA


United Airlines flight 175 – N612UA


American Airlines flight 77 – N644AA


United Airlines flight 93 – N591UA
