Salon.com News | U.N. nuke alert: "Electronic drawings that give comprehensive details of how to build and test equipment essential for making nuclear bombs have vanished and could be for sale on the international black market, according to U.N. investigators. The blueprints, running to hundreds of pages, show how to make centrifuges for enriching uranium. In addition, the investigators have been unable to trace key components for uranium centrifuge rigs and fear that drawings for a nuclear warhead have been secreted away and could be for sale."
