Perhaps. The Tomahawks' sophisticated systems make them ideal for such pinpoint attacks. Their onboard computers are programmed with highly detailed radar maps to the target, and they coordinate with satellites to make sure the missiles are in the right place. But they are not good at everything. They can knock out office buildings and other unhardened structures, but because their warhead contains just 1,000 lbs. of high explosive, they do not pack enough punch to take out bunkers, caves or fortified buildings...
...real recession (classically defined as two consecutive quarters or more of negative growth)? Through most of the increasingly boomy 1990s, American businessmen, workers and consumers by and large would have answered, Who cares? None of the three versions of economic contraction registered even as blips on the national radar screen. But brace yourself: it may be time to make those painful distinctions. The consensus of TIME's Board of Economists, which convened recently in Manhattan to assess the outlook through next year, is that the issue is no longer academic. It is practical and even pressing...
...turn left to lose altitude. Still descending, the pilot next reported, "We must dump some fuel." At 9:24 he declared an emergency, saying, "We are starting to vent now. We have to land immediately." The plane was cleared for dumping. Six minutes later, it disappeared from the radar...
...again, controllers vainly sent signals to where they thought SOHO should be. Weeks went by without a response. Then, in mid-July, a University of Colorado physicist named Alan Kiplinger had an idea. Why not search for SOHO the same way flight controllers look for commercial airliners: with radar? Realizing that extremely powerful radar would be needed to bounce a signal off so distant a target, he called on Donald Campbell, the chief scientist at the world's largest radiotelescope, the 1,000-ft. dish at Arecibo, Puerto Rico. Campbell agreed to try, although he estimated that the power...
...July 23, Arecibo directed a powerful high-frequency radio beam toward the site SOHO should have been, a million miles away orbiting the sun. Ten seconds later, NASA's 230-ft. radiotelescope at Goldstone, Calif., began picking up its faint radar profile, barely perceptible against the background noise of space...
