What to expect when the NSA calls you
Dave instructed me to hang up the phone and dial 411 (information) and ask the operator for the main number to the naval base in Bethesda, MD. I was to call that number and then work my way through a series of other base operators, asking each in turn to connect me to the next one in the chain. He gave me the exact words to say at each hop since I’d be asking to be put through to a secure facility.
