How Did the C.I.A. Lose a Nuclear Device?

In 1965, a covert CIA mission to place a nuclear device on Nanda Devi, a Himalayan mountain, ended in failure when the device was lost. The mission, aimed at spying on China, involved American and Indian climbers who abandoned the device during a blizzard. Despite efforts to locate it, the device remains missing, raising concerns about potential environmental and health risks. The mission remained secret until a 1978 exposé, leading to diplomatic tensions between the U.S. and India. Today, the lost device continues to be a source of concern and mystery.
