Great flashes often struck out of the volcanic plume, usually hitting the newborn island near the active vent, and almost every time, the scientists' instruments showed a strong charge of positive electricity in the plume just before the flash. After the flash, the plume was neutral or negative, building up a positive charge before the next flash. This happened repeatedly without any thundercloud forming in the vicinity, proving that the volcano alone was generating the electricity. Just how it did this is still uncertain. In some cases, the positive electricity was created when a high-speed...
...volcano can make its own lightning, without "thunderclouds, a team of U.S. and Icelandic scientists studied the volcano that is forming the new island of Surtsey off the coast of Iceland. In Science, they report that they rode a fishing boat to within 250 yds. of the roaring vent, and flew in an airplane close to the hot, black plume. Once they saw rocks a foot in diameter tossed above their plane. They escaped injury and satisfied their curiosity: volcanoes do manufacture lightning...
...William James Center for the Behavioral Sciences, the problem was analyzed very carefully: "They were testing the air conditioning, and the steam from the roof vent condensed and looked like smoke. The red glow from the airplane warning light on the roof colored the steam. They're still testing the air conditioning and we're still freezing...
Worrying about Cambridge's frayed nerves, James W. Ingraham, Superintendent of Buildings and Grounds in the North Yard Area, offered some solutions: "The atmosphere has to be just right to get the smoke effect, and we might be able to move that signal light away from the vent. Or perhaps the FAA would let us put in a green...
Well trained in both conventional and guerrilla warfare, the Chinese foot soldier is amply armed with Chinese-made automatic weapons-usually a stamped copy of the Russian World War II vent-barreled burp gun. He is supported by light and medium mortars, bazooka-style rocket launchers, recoilless rifles, and artillery that in performance ranks with the best in the world. As to armor and transport, Mao's millions are woefully underequipped. Some 4,000 Russian T-34 tanks are still operating, but though that machine was first-rank armor during the Korean War, it is now obsolete. Still, armor...
