September 10, 2001 (F): Atta calls Khalid Shaikh Mohammed, the operational planner of the 9/11 attacks, in Afghanistan. Mohammed gives final approval to Atta to launch the attacks. This call is monitored and translated by the US, though it isn't known how quickly that takes and the specifics of the conversation haven't been released. [Independent, 9/15/02] The NSA had been intercepting calls between Mohammed and Atta for the past several months, and Mohammed was already on the FBI's Most Wanted list at the time (see Summer 2001). Shouldn't Atta's location have been determined from these calls with a high profile terrorist (just as bin Laden's location was determined in 1998 from his phone use)?
