“Operation Gold” was a 1950s project conducted by the CIA and the British Intelligence Service to tap into Soviet communications by tunneling from West Berlin into East Berlin, Germany. Known as “Operation Stopwatch” by the British, the 1,500 foot tunnel was active for eleven months, and netted about 40,000 hours of East German telephone conversations - even though the KGB knew about the tunnel before it was built. Retired CIA officer Lou Mehrer tells the story of the Berlin Tunnel at the Herbert Hoover Presidential Library & Museum in West Branch, Iowa.
