From this PBS documentary on the NSA (hi Fort Meade!).
Phone numbers of Osama bin Laden and a Yemeni associate in San Diego, circa 2000:
001-858 279 1159
Coincidence no. 1:
If General Hayden [at the NSA] had simply looked out his window ... a few miles away he might have been able to see the motel where the terrorists were staying.
You have two groups: the terrorists who were planning the biggest attack on the US in history, and the analysts who were listening to some of their phone calls for years. And they were living in the same neighborhood.
