WITH SWEAT SLIDING DOWN HIS BROW, scientific sleuth James Starrs shoves a long steel probe down through the dirt around the grave of American explorer Meriwether Lewis. A few moments later, his team drags a radar sled across the same neatly clipped grass and around the weathered limestone monument. Their mission: to learn the truth of Lewis' mysterious death by gunshot here on a Tennessee stretch of the Natchez Trace, the old road between Natchez, Mississippi, and Nashville, Tennessee, nearly 183 years ago. Did this pioneer, whose trek to the Pacific Northwest with William Clark has been a staple...
...last month it was Lewis' turn: Starrs was using his radar probe to locate the explorer's remains. If the data show anything worth digging up, the scientist would have to obtain permission from the U.S. Department of the Interior and Tennessee authorities to do so. Lewis' descendants already support the project. Once the explorer is out of the ground, Starrs could use several technological tools that can coax secrets from the dead. Modern lab tests can detect the tiniest traces of poison or gunpowder residue, DNA analysis can help make identifications and scrutiny with scanning electron microscopes can reveal...
When a British Hercules transport plane heading away from Sarajevo was tracked by ground-based radar, U.N. peacekeepers on the ground responded by closing the airport. It reopened two days later but closed briefly on Saturday after mortar fire hit the U.N. headquarters...
...incidents raised the possibility of U.S. and Western involvement in the fighting, if it resumes. Four Yugoslav planes buzzed two American warships in the Adriatic. Though no shots were fired, three of the planes turned back only after American radar had locked on to them -- a preliminary step to shooting. In Sarajevo a Canadian member of the United Nations peacekeeping force exchanged fire with a Serbian sniper, who was killed. Some Western officers fear that similar incidents could trigger a kind of unplanned, back-door military intervention. But the Western powers are still determined to avoid deliberate intervention, and soon...
...ground-based interceptors by 1997 -- rather than 2002, as he recommends -- to fend off small-scale nuclear attacks cannot proceed without major cost overruns and performance problems. In the rush to deploy, he says, the military will have to design and start buying SDI before any of the missiles, radar or communications involved are tested. That is hardly a recipe for success: the record of earlier ground-interceptor tests has been ; spotty at best. The proposal, says Chu, violates the fly-before-buy principles that Pentagon leaders "have labored so hard to put into place." At week...
