FBI Refuses To Confirm Identity Of 9/11 Planes


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

Aidan Monaghan

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.”

(See NTSB source links provided below)

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

  • Aidan;

    My grandmother was Helen Monaghan. She married William Long, from Philadelphia, and raised a family, including my mother, Ruth, in Hornell, N.Y. Maybe we're cousins somehow.

    I got your name from an article by Doug Herman that was posted on rense.com 5-21-8. Great work you're doing. I watched the short video about Cheney. I remember reading , shortly after the attacks, that a junior congressman, a republican, I think, said he passed Cheney in the hall outside the bunker a little before 8:30 am the morning of the attack. Can't recall the lawmaker's name. I believe I read that on AlterNet.

    Waiting For The Signal

    These pages that bring us together

    are the fire in the cave above the stream,

    a dream we move in and out of, faceless,

    expendable, waiting for a burst of wings

    to spill our pooled bones like coins

    over the chilled and silent ground

    we fell in love with so long ago,

    singing the green hills homeward

    under that shovel-shouldered sun.

    Fatigue works grim the stone of souls.

    No talk is needed to believe the bleeding

    will be ours all too soon. Needled dust,

    that settled itself in naive lungs, cuts

    with each rasp, yet the bleeding

    won't be stemmed. Quick, black tongues

    flick from windows, floors below dustified

    debris, and the Street slumps with peanuts

    beside its beer, locked on the game.

    In our rush of voices a stream curses

    the murmur of pines. In our names,

    what we begged for never to be done,

    is done with no shame. And the day

    drags its blindered self to toil. Night trades

    whiskey pete for oil, while down slope,

    death-drummer birds with blazing eyes

    ascend the holy crags to kill dissent

    before we waking innocent arise.
