...excellent television address, the nuclear test ban treaty just negotiated with the Soviet Union and the United Kingdom is not the beginning of the millenium. Rather, it is an extremely limited document, providing only for an end to non-underground tests. These explosions, which are relatively easy to detect, poison the atmosphere without necessarily improving the military position of the country making them. The cessation of these explosions, while possibly reducing international antagonism, does not mean the end of rivalry between the great powers, and it does not make future nuclear confrontations impossible...

Among the current ins: Mr. Magoo, electric toothbrushes, army toys, English bikes, kosher foods, pizza pies, and Frankenstein monsters...
...turbine blades with electronically generated sound to see if the blades resonate at a frequency that indicates there is no danger of breakage. Westinghouse uses ultrasonics -super high-frequency sound waves - to probe right through big forgings in the rotors of its giant $2 million turbine generators and detect air pockets or cracks inside the metal; since it began this test, Westinghouse has not had a single forging break on the job. An ultrasonic tester used by Republic Steel can measure the thickness of a coat of paint or locate an air pocket 40 ft. deep in solid steel...
...thousandth of an inch in diameter were found inside transistors in the Polaris missile, the Air Force has insisted that all the transistors in missile components be Xrayed. Companies have discovered that "preventive" testing produces safer and more efficient products, and also cuts costs by making it easier to detect and correct flaws. Manufacturers of machinery and airframes spend 13% of their production costs on nondestructive testing, are convinced that otherwise they would lose 45% of their production because of faulty quality. "Every time you have to do something over again," says Lockheed Aircraft Tester Harvey Christen, "you duplicate your...
