How the CIA Lost a Plutonium Battery

In 1965, the Cold War was running very hot, and in an effort to spy on the Chinese, the CIA mounted an expedition to Nanda Devi, a mountain in northern India, to place a listening device. Unfortunately, bad weather forced the team off the mountain, abandoning the device in the process. It proceeded to sink into the surrounding glacier, and is still there today. Worse, it's powered by plutonium, which may or may not be slowly seeping into a rather important river: the Ganges. Recently, we caught up with Pete Takeda, author of An Eye at the Top of the World about the botched CIA plan. Watch the first part in a three-part interview.
