Defense Department historians release a book chronicling the September 11 attack on the Pentagon. The 250-page book includes the accounts of survivors, rescuers, and emergency responders, and includes previously unpublished photos of the wreckage, aircraft parts, and rescue efforts. [Fayetteville Observer, 9/13/2007; Washington Post, 9/27/2007] Titled Pentagon 9/11, it is published by the Historical Office of the Office of the Secretary of Defense, in collaboration with the Naval Historical Center, and with the assistance of the Army, Air Force, and Marine Corps historical offices. [US Department of Defense, 9/10/2007] More than 1,300 interviews were collected for it (see October 2001-September 11, 2002), of which the authors used more than 300 in putting together their account. [Washington Post, 9/27/2007] Randy Papadopoulos, a historian with the Naval Historical Center who co-authored Pentagon 9/11, calls it “the first scholarly study of what happened at the Pentagon on 11 September 2001.” [American Forces Press Service, 9/7/2007] Reportedly, one reason for writing the book was to counter skepticism and alternative theories that suggest the US government was behind the attack, and a missile rather than a hijacked aircraft hit the Pentagon (see Early March 2002). [Washington Post, 9/27/2007] Diane Putney, one of the book’s authors says, “I have no doubt it was American Airlines Flight 77 [that hit the building].” Her conclusion is reportedly based on a piece of the plane that was discovered, which bore the American Airlines logo.
