According to an FBI report, “FBI investigators have officially concluded that 11 of the 19 terrorists who hijacked the aircraft on September 11 did not know they were on a suicide mission.”
“Unlike the eight ‘lead’ attackers, who were all trained pilots, they did not leave messages for friends and family indicating they knew their lives were over,” and they did not have copies of Mohamed Atta’s final prayer note (see September 28, 2001). Personal items found suggest the men thought they were taking part in a conventional hijacking and were preparing for the possibility of prison. [Observer, 10/14/2001] This is later contradicted by video filmed in Afghanistan in March 2001 showing several of the 11 non-lead hijackers proclaiming their willingness to die on an upcoming suicide mission (see (December 2000-March 2001)).
