Sound like all the ingredients for a good spy thriller. Lessee, we could have one of the bombs rattle loose and bury itself in Death Valley, not far from a prospector's shack. The prospector finds the bomb a few weeks later and thinking it was a dud, covers it with some tailings and forgets about it for a few years. Needing to replace a water trough that fed his sluice, he remembers the dud and decides to dis-assemble the missile and salvage the casing.
Somebody should sell the idea to Tom Clancey. He'd love it.
