...system (see diagram), which has now been completed along roughly one-sixth of the frontier, the first fence has been eliminated, while a deep, concrete-lined ditch has been added. It is intended to thwart would-be escapees trying to crash the border in cars or trucks. West of the ditch is a minefield, then a new close-meshed wire fence that begins 3 ft. underground (to prevent tunneling) and rises 10 ft. above the earth...
That was time enough. While the diversions went on, seven prisoners were making a dash for another section of the wall at the northern corner of the yard (see diagram). As usual during routine operations, the tower nearest to it was unmanned. The men erected a makeshift ladder crudely fashioned out of iron water pipes stolen from the prison's plumbing. Frantically, the men scrambled up the ladder and wiggled under the 2,300-volt electrified barbed wire that ran 18 in. above the top. At about that moment, all of the phones inexplicably went dead in the prison...
...system will double the accuracy, or halve the "circular error probability," of each of the 1,650 Minuteman warheads. The current version has a fifty-fifty chance of falling within 1,200 ft. of its target; the new model would be even odds to land within 600 ft. (see diagram...
...Using their new biochemical tools, the scientists embarked upon some remarkable experiments. As usual, they turned to their favorite guinea pig, a lab strain of E. coli, and soon they had learned to insert with exquisite precision new genetic material from other, widely differing organisms into the bacteria (see diagram...
...fear of causing such a crash or a collision ?known with studied casualness as creating an "aluminum shower"?puts the controllers under tremendous strain from the time they clear a jet for takeoff until they guide it to a landing (see diagram). FAA psychological tests have shown that controllers undergo more stress than combat pilots. At Chicago's O'Hare Airport, the world's busiest, they are allowed to work for only 90 minutes at a stretch during peak hours, landing a plane every two minutes while simultaneously keeping track of half a dozen more...
