September 11 (9/11) Attacks
Bin Laden gave Approval for Mohammed to go forward
In early 1999, bin Laden gave approval for Mohammed to go forward with organizing the plot. Mohammed, bin Laden, and bin Laden's deputy Mohammed Atef held a series of meetings in early 1999. Atef provided operational support, including target selections and helping arrange travel for the hijackers. Bin Laden overruled Mohammed, rejecting potential targets such as the U.S. Bank Tower in Los Angeles for lack of time.
