...politically acceptable and scientifically credible basing mode for its sophisticated bird. Reagan, Weinberger and a flurry of military papers and briefings had all failed in the rush to sell Dense Pack, the basing plan that would plant 100 of the 71-ft.-tall missiles in a 21-sq.-mi. strip of Wyoming, 14 miles long by 1.5 miles wide. Proponents argued that because the missiles would be clustered so closely, incoming Soviet rockets theoretically would destroy one another, and superhardened silos would protect most of the MX missiles from destruction. The survivors would then rise to retaliate, knocking...
Putting all of America's MX eggs in one basket seems to defy common sense. But there is a certain logic to Dense Pack that can only be understood in terms of the strange and fearsome technology involved. The closer the Soviet missiles come to the 21-sq.-mi. Wyoming strip, the closer they come to each other. When the first finally explodes just above its target, its apocalyptic power is turned against fellow Soviet missiles. Its blast, and those of any succeeding warheads that manage to detonate, would cause mutual missile annihilation known in the lexicon of strategic...
...Islamic Guard units and including some basij, or groups of teen-age zealots, staged a new offensive. Attacking at night to neutralize Iraq's overwhelming air superiority, and sticking to the high, steep terrain that favors Iranian manpower over Iraqi firepower, they claim to have captured 210 sq. mi. of territory, killing 6,100 Iraqi defenders and taking 3,400 prisoners. The attackers penetrated three to six miles into Iraq, seizing positions within shelling range of a strategically important highway linking Baghdad to the port of Basra, 280 miles to the south...
...concern centers on the July 1, 1997, deadline when, under the terms of Britain's 99-year lease, more than 90% of Hong Kong's land area, the 373-sq.-mi. New Territories, will revert to China. (Treaties signed in 1841 and 1860 give Britain ownership of the remaining 34 sq. mi.-Hong Kong island and portions of Kowloon-" in perpetuity.") Although an arrangement short of total reversion may eventually be worked out between London and Peking, permitting Hong Kong to continue to function as it does now, some fear that China will insist on full sovereignty. That...
...size Brazilian cities. The dam's 18 turbines, weighing 300 tons apiece, are so large that the Symphony Orchestra of Brazil once managed to stage a performance inside one of them as it traveled to the dam site. Itaipu's reservoir has submerged more than 563 sq. mi. of tropical forests and farm land, and also drowned one of South America's most impressive natural cataracts, Sete Quedas. As gargantuan as Itaipu's physical dimensions is its potential output of 12,600 megawatts. That is twice the power of the Grand Coulee and six times that...
