About this episode

This episode discusses the CIA's loss of a nuclear device in India during the 1960s and the subsequent investigation by journalists.

In the 1960s, the CIA lost a plutonium-fueled generator on top of a mountain in India. The generator was supposed to power an unmanned listening station, intended to pick up signals from China’s missile tests. But when mountaineers ascended the near 26,000-ft Nanda Devi – under the guise of studying the environment – weather got in their way. They left the nuclear device behind and months later, when they returned, it was gone. New York Times reporter Jeffrey Gettleman reconstructed this event with a team of journalists. The story took about seven years, thousands of miles, and earning the trust of many men who had grown old and have since passed away.
