Osama bin Laden flew with his family to Indiana in 1979 to meet with his jihad-mentor Abdullah Azzam. They he flew by himself to Los Angeles for 'meetings' (presumably to recruit engineers for his family's construction business.). All this according to a book by his first wife Najwa bin Laden and their son Omar. Somehow, Abdullah Azzam doesn't seem like the Indiana type. A few years later, the CIA had him back for a return visit.
