A few hours after the attacks, German intelligence intercepts a phone conversation between followers of bin Laden that leads the FBI to search frantically for two more teams of suicide hijackers, according to US and German officials. The Germans overhear the operatives refer to “the 30 people traveling for the operation.” The FBI scours flight manifests and any other clues for more conspirators still at large. [New York Times, 9/29/2001] Two days later, authorities claim to have identified teams of as many as 50 infiltrators who supported or carried out the strikes. About 40 are accounted for as dead or in custody; ten are missing. They also believe a total of 27 suspected operatives received some form of pilot training. This corresponds with many analyses that the attacks required a large support network. [Los Angeles Times, 9/13/2001] Yet there is no evidence that any accomplices in the US shortly before 9/11 have since been arrested or charged.
