CIA Lost Nuclear Generator in Himalayas in 1965, Still Missing

The Lost Device The core of the claim is true: in 1965, a CIA mission, with Indian cooperation, lost a plutonium-powered nuclear generator in the Himalayas while trying to monitor Chinese nuclear tests [1][2][3][4][10]. China's first nuclear test occurred in 1964, prompting this surveillance effort [5][6].

The device was abandoned during a storm on Nanda Devi and has remained unrecovered [1][3][4]. Potential Environmental Impact While the claim correctly identifies the potential for plutonium leakage and the dependence of millions on the Ganges River, it overstates the certainty and scope of the environmental danger.

Scientific assessments suggest that while localized risks exist, the vastness of the Ganges River would likely dilute the plutonium, making widespread poisoning less probable than the claim implies [1]. The device is described as a generator or spy equipment, not a reactor [1][2][3][4][10].
