“On June 10 [2000], [future 9/11 hijacker Khalid al] Mihdhar exposed the planes [as missiles] operation to potential compromise when he flew home, unannounced, to visit his family in Yemen. KSM [Khalid Sheikh Mohammed, who oversaw the 9/11 plot] was outraged by this undisciplined act, and sought to drop Mihdhar from the planes operation, but bin Laden intervened on his behalf.”
