June 2001: Moussaoui Expresses Interest in Crop-Dusting

Zacarias Moussaoui, living in the US, makes some professional inquires about crop-dusting. He uses the pretext of launching a crop-spraying company. Information about this, including a computer disk about the aerial dispersal of pesticides, will be found on Moussaoui’s computer after 9/11. [Gunaratna, 2003, pp. 146] Roughly around the same time, Mohamed Atta expresses interest in flying crop-duster planes (see March-August 2001). Counterterrorism expert Rohan Gunaratna will later comment that this suggests al-Qaeda was already working on another plot using crop-duster aircraft to distribute unconventional weapons.
