Scores of accidents involving nuclear reactors and weapons
have occurred worldwide since the Nuclear Age began in 1945.
And an estimated 50 nuclear warheads still lie on the bottom of
the world's oceans, according to Joshua Handler, a former
research coordinator for the environmental activist organization
Greenpeace.

Presumably our spookbirds watch the oceans for
non-US recovery teams fishing for plutonium.
Do the russians watch the oceans for their lost toys, including
dead nuke subs and ocean-dumped 'spent' reactors?
