...hold its shape only at weightless, airless altitudes, that wide wing is the working element of a satellite, built by Fairchild Hiller Corp., for detecting micrometeoroids. Pegasus' 208 rectangular panels are covered on both sides with thin sheets of copper and aluminum separated by plastic. The metal sheets are electrically charged, but normally no current flows between them. When a micrometeoroid penetrates the aluminum, it will punch a hole in the plastic and fill the hole with metal vapor that is a good conductor of electricity. Although the gas will dissipate quickly, there will be time for a brief...
More than two hours passed before the first flotsam of disaster bobbed to the ocean surface. Then Coast Guardsmen began fishing out the remains: shreds of metal covered with flesh, a child's mitten, a blue snowsuit, a stewardess' jacket, a woman's mohair coat, a paperback copy of Call It Sleep, and-eventually-the body of a little boy. Part of the cockpit floated up, and when rescuers began to lift it out of the water, the headless body of a crew member flopped out into the water...
...Garden Clubs. Minnesota's Senator Eugene McCarthy has even urged the use of excise taxes on gasoline to subsidize the scrapping of cars. The trouble is twofold: 1) as population and incomes increase, more cars are made, and they have ever shorter lives; 2) the price of scrap metal has dropped as the steel industry has converted from open-hearth furnaces, which use up to 45% scrap metal, to oxygen furnaces, which use only 27% scrap. The price an auto wrecker gets for his scrap has fallen to around $10 a car, with the result that many wreckers have...
Originally a Canadian innovation (the Mounties use them to track their man), the machine grips all kinds of snow with a tanklike traction belt of metal cleats. Outboard Marine Corp., maker of Evinrude and Johnson motors, produced two new U.S. models priced at $895, and found it had started something of a fad. The number of snowmobiles sold nationally jumped to 10,300 this year, double last year's sales...
...talk turned to molybdenum, which is not the hardest metal known to man but has the advantage of not even beginning to melt at temperatures up to 4,700°F. Eventually the atom experts decided to put their drilling theories to a test; they constructed a 2-in. cylindrical drill bit of molybdenum, and to their surprise their very first demonstration was a success. With a 5-kw. generator, they heated the face of the bit to 2,190°F, then forced it down against a specimen of hard basalt rock. Like a hot pick thrusting through...
