US intelligence is aware from monitored phone calls that Nawaf Alhazmi is travelling to an important al-Qaeda summit in Malaysia (see January 5-8, 2000). Alhazmi is known to be in Karachi, Pakistan, with a ticket to Malaysia for January 2, 2000. CIA and Pakistani officials plan to have his passport scrutinized as he passes through the airport, but he changes his ticket departure date twice. Officials get confused and are not there when he leaves the country, so they still don’t learn his last name. [Stern, 8/13/2003] The 9/11 Commission later notes that “officials could have worked on logical flight itineraries and perhaps realized that Nawaf could and probably did keep to his original plan.” But not only is this not done at the time, apparently the flight manifests are not checked after the fact to see in anyone with the name Nawaf had boarded. [9/11 Commission, 1/26/2004, pp. 6 ] Even after being monitored for several days in Malaysia, US intelligence supposedly still will not learn his last name (see January 5-8, 2000 and Shortly After).
