On December 29, 1992, future World Trade Center bomber Ramzi “Yousef told [co-conspirator Ahmad] Ajaj he wanted to get hold of the bomb-making manuals that had been in Ajaj’s luggage when the INS [Immigration and Naturalization Service] stopped him. …The call was taped by the prison recording system, but apparently not reviewed until much later.”
