Cover-up allegations
Conspiracy theorists say they detect a pattern of behavior on the part of officials investigating the September 11 attack meant to suppress the emergence of evidence that might contradict the mainstream account.
Cockpit recorders
According to the 9/11 Commission Report, the cockpit voice recorders (CVR) or flight data recorders (FDR), or “black boxes”, from Flights 11 and 175 were not recovered from the remains of the WTC attack; however, two men, Michael Bellone and Nicholas DeMasi, who worked extensively in the wreckage of the World Trade Center, stated in the book Behind-The-Scenes: Ground Zero that they helped federal agents find three of the four “black boxes” from the jetliners:
“At one point I was assigned to take Federal Agents around the site to search for the black boxes from the planes. We were getting ready to go out. My ATV was parked at the top of the stairs at the Brooks Brothers entrance area. We loaded up about a million dollars worth of equipment and strapped it into the ATV. There were a total of four black boxes. We found three.”
Ted Lopatkiewicz, spokesman for the National Transportation Safety Board, remarked that “It’s extremely rare that we don’t get the recorders back. I can’t recall another domestic case in which we did not recover the recorders.”
According to the 9/11 Commission Report, both black boxes from Flight 77 and both black boxes from Flight 93 were recovered. However, the CVR from Flight 77 was said to be too damaged to yield any data. On April 18, 2002, the FBI allowed the families of victims from Flight 93 to listen to the voice recordings. In April 2006, a transcript of the CVR was released as part of the Zacarias Moussaoui trial. Some conspiracy theorists do not believe that the black boxes were damaged and that instead there has been a cover up of evidence.
Bin Laden tapes
A series of interviews, audio and videotapes have been released since the 9/11 attacks that have been reported to be from Osama bin Laden. At first the speaker denied responsibility for the attacks but over the years has taken increasing responsibility for them culminating in a November 2007 audiotape in which the speaker claimed sole responsibility for the attacks and denied the Taliban and the Afghan government or people had any prior knowledge of the attacks. According to the Central Intelligence Agency, the speaker was most likely Osama bin Laden. Some observers, especially people in the Muslim world, doubt the authenticity of the tape.
