The rest of the hijacking crews were made up of two veteran Al Qaeda operatives, a replacement pilot and a group of young Gulf Arab volunteers, chosen from what Mohammed described as "a big excess of brothers who were filled with desire for martyrdom," whose job was mainly to effect the physical takeover of the airliners.
As Sept. 11 approached, intelligence agents in the West were nearly beside themselves with anxiety. They knew something was going to happen, but they couldn't figure out what. Mohammed was already moving on. He spent the weeks before Sept. 11 instructing a new Canadian recruit on communications protocols. He was sending the recruit to Southeast Asia to coordinate a bombing campaign in the Philippines and Singapore. The only acknowledgment that something big was afoot was his suggestion that the recruit should probably leave Pakistan before Sept. 11.
It is that sort of unrelenting focus that makes Mohammed such a feared figure among those who pursue him. He simply does not stop.
In the months after Sept. 11, investigators think that Mohammed was moving back and forth between Pakistan and Afghanistan. One Afghan general, Ziaudeen Deldar, said intelligence reports indicate that "Khalid the Baluchi" was among hundreds of Al Qaeda fighters who escaped on foot to Pakistan from a camp near Shahi Kot in southeastern Afghanistan last spring when American forces launched Operation Anaconda -- an attempt, they said, to finish off Al Qaeda.
Instead, the Americans faced considerably more resistance than anticipated and backed off. The grasp of the anaconda relaxed and the prey, including Mohammed, slipped away. Weeks later, Al Qaeda operatives blew up a truck outside a synagogue in Tunisia, killing 19 people. In the days leading up to the attack, investigators say, one of the bombers was in frequent telephone contact with a man in Karachi -- Mohammed.
Mohammed was accompanied at the Al Jazeera interview by Ramzi Binalshibh, another Hamburg man who had wanted to become one of the suicide pilots but who tried and failed four times to obtain a U.S. visa. Binalshibh instead became Mohammed's field coordinator for the plot.
It's noteworthy that in the interview, Mohammed let Binalshibh do most of the talking. Even in granting an interview, the purpose of which ostensibly was to reveal, he exposed almost nothing.
