 In 2006, in response to 9/11 conspiracy theories surrounding its original news story, the BBC said that confusion had arisen with the common Arabic names, and that its later reports on the hijackers superseded its original story.In 2005, U.S. Army Lt. Col. Anthony Shaffer and Congressman Curt Weldon alleged that the Defense Department data mining project Able Danger identified Mihdhar, Hazmi, Shehhi, and Atta as members of a Brooklyn-based al-Qaeda cell in early 2000.Shaffer largely based his allegations on the recollections of Navy Captain Scott Phillpott, who later recanted his recollection, telling investigators that he was "convinced that Atta was not on the chart that we had".
