...Francisco for nine turbulent years, from 1978 to the end of 1987. "People sometimes misjudge me. I am very much a street person," Feinstein claims. "I know, I don't look like it. And this is where I've been underestimated. People think I'm in some kind of shell...
...Children as young as eight fight enemies they do not know for causes they barely understand. War does not rob a child of youth so much as it reveals his innocence: ignorance of death and a nervy imperviousness to danger, revealed in a boy's grin when a mortar shell falls close or in his eagerness to fire when instinct should tell him to duck...
Almost certainly, an unintentional blast would detonate only the chemical explosives that, if fired deliberately, would compress the warhead's plutonium cores and touch off an unstoppable atomic chain reaction. Some experts see a slim chance of a nuclear explosion in the case of the W-79 artillery shell, but the far more likely result would be a chemical blast that could release deadly radioactive plutonium or uranium from the cores. The safety problems, disclosed last week by the Washington Post, were promptly confirmed in public congressional hearings. The difficulties seem sure to complicate immensely a review under...
...story begins in 1988, when scientists at the Lawrence Livermore National Laboratory near San Francisco set some new, supersophisticated computers to simulating the effects of nuclear blasts. One unexpected conclusion: the chemical explosives in a W-79 artillery shell could be detonated if the shell were struck in a single sensitive spot, perhaps by a stray bullet. One military official told the Washington Post, "For a while, we were also worried that these things might go off if they fell off the back of a truck." More than 300 of the shells were reportedly shipped to the U.S. from West...
...common thread in the three systems," says Exon, "is the problem of previous-generation high explosives." All three weapons carry them, rather than a less volatile Insensitive High Explosive, which is heavier and thus decreases the range of a missile or artillery shell. By presidential order IHE nonetheless has been used in all new weapons built since 1985 -- with, however, at least one exception. Even after that date, defense planners decided not to switch to IHE in the Trident W-88 warhead. That is a design trade-off that the Pentagon may soon bitterly regret...
