December 31, 1999-January 2, 2000: Al-Qaeda Operative Cases Airplane Security

Al-Qaeda leader Khallad bin Attash, cases four flights to aquire basic information about how a hijacking might be conducted. Starting from Kuala Lumpur, Malaysia, he flies to Bangkok and then on to Hong Kong, before returning to Malaysia via Bangkok. He will later tell a CIA interrogator that he took a box cutter onto the plane but that security did not notice it. While in Malaysia he and fellow operative Abu Bara al Taizi initially stay with Jemaah Islamiyah leader Hambali and at the Endolite clinic, where Khallad receives a new prosthesis. Presumably, he shares what he learned at the al-Qaeda summit in Malaysia attended by two or three 9/11 hijackers that is held in Malaysia a few days later (see January 5-8, 2000).
