9/11 mastermind Khalid Shaikh Mohammed (KSM) attempts to organize a follow up attack to the 9/11 attacks. Beginning in October 2001, KSM and Hambali, a top al-Qaeda leader in Southeast Asia, recruit four operatives for the new plot, all of them Malaysian: Mohamad Farik Amin (a.k.a. Zubair).
Mohammed Nazir Bin Lep (a.k.a. Lillie).
Zaini Zakaria.
Masran bin Arshad.
The plan is for these operatives to blow up the doors to airplane cockpits using shoe bombs, take over flying the aircraft, and then crash them into US buildings—essentially the same technique as was used in the 9/11 attacks, except with the addition of the shoe bomb and the use of East Asians instead of Middle Easterners. Apparently several buildings are initially targeted. KSM will later name them as the Library Tower in Los Angeles (later renamed the US Bank tower), the Sears Tower in Chicago, the Empire State Building in New York, and a tall building in Washington State. But the plot soon focuses on just the Library Tower, the tallest building on the West Coast of the US, due to a lack of pilots. The members of the plot go to Afghanistan and swear an oath of loyalty to Osama bin Laden, and then continue to train with Hambali in Asia. However, the plot does not go far because Zakaria, the only trained pilot of the group (see (Spring 2000)), drops out in late 2001, saying he has small children to consider. In February 2002, bin Arshad, the leader of the four operatives, is arrested and other other members decide the plot has been canceled. Zakaria turns himself in to Malaysian authorities in 2002, and apparently remains in detention in Malaysia without being charged. Amin and Bin Lep will be arrested in 2003 with Hambali and taken into US custody (see August 12, 2003). Amin, Bin Lep, and Hambali will all be transferred to Guantanamo prison as high-value detainees in 2006 (see September 2-3, 2006). It is unknown who arrests bin Arshad or what becomes of him.
