The grim failure of Operation Hat resurfaced this month after violent floods killed over 50 people in the Indian state of Uttarakhand. The floods most likely began when a chunk of the Nanda Devi glacier broke off and trapped flowing water, forming a lake that eventually burst through and swept through nearby valleys. The undeniable oddness of a glacial breaking apart during the winter has led some locals to speculate that perhaps the plutonium generator, which is still likely producing heat, led to the deadly floods.

There’s no evidence for the hypothesis, though even after years of reconnaissance missions and rigorous chemical assays of the surrounding area, nobody knows where the CIA’s lost nuclear powered spy oven is.
