Arms dealer Victor Bout secretly sells twelve heavy-duty cargo planes to the Taliban. They are given false registries as civilian aircraft belonging to Ariana Airlines, Afghanistan’s national airline. The planes enable the Taliban to buy and transport more weapons and move al-Qaeda and Taliban figures more easily. The Taliban usually purchase the additional weapons from Bout as well. When US forces take control of Afghanistan in late 2001, they will discover huge caches of munitions that had been flown into the Kandahar airport before 9/11 and generally hidden in storerooms near the airport. Al-Qaeda and Taliban share the caches, and likely use remnants of them in fighting the US in late 2001, 2002 and beyond. Apparently, US intelligence does not notice the airplane purchases until after 9/11. [Farah and Braun, 2007, pp. 126-129, 279]
