...desperate and imaginative efforts to clear fog from airports, highways and other critical areas, meteorologists have used giant fans, rotating racks strung with nylon strands and chemicals dropped from planes or spewed up ward from strange machines on the ground. Now the U.S. Air Force thinks that it has found a practical new weap on in the continuing fight against fog: the helicopter...
During research into the meteorology of fogs, scientists at the Air Force Cam bridge Research Laboratories in Bed ford, Mass., concluded that there might be a simple way to disperse mists that develop when moist air near the ground is cooled at night. The researchers reasoned that if the warm, drier air above could somehow be driven down into the moist blanket of fog, it would cause suspended water droplets to evaporate, thus clearing...
...routine developed during three foggy weeks of tests, a helicopter was flown to an altitude of 500 ft. above the mist, where it hovered until the turbulence of its downdraft traced a cir cular outline about 5,000 ft. in diameter on the upper layer of fog. The chopper then descended to 100 ft. above the fog and, at a speed of 30 m.p.h., began to fly in a gradually enlarging spiral pattern until it reached the edge of the circular outline. Within a minute, the fog began to fade away at the center of the circle. Ten minutes later...
...face mask for added warmth. But nothing seemed to help much. On the second day the temperature dropped to 70° below zero. As the snowmobilers plowed ahead through Moose Creek and the village of North Pole, the freezing exhaust of their engines created a tunnel of ice fog. Visibility was reduced to less than...
Lost Winners. Tony Burkel, a 41-year-old turkey rancher from Greenbush, Minn., and a professional driver for the U.S.'s Polaris Industries Inc., which makes the Polaris snowmobile, was among the first drivers to arrive in Fairbanks, but he got lost in the dense ice fog. Officials at the finish line, who could hear his machine growling aimlessly around the side streets, finally sent out a runner to try to guide him home with a flare. Another contestant gone astray startled onlookers by barreling across the finish line from the opposite direction...
