Cache. In Knoxville, Tenn., police discovered that the $150 for which John Maples was searching had fallen through a hole in his pocket into the hollow center of his artificial...
Within minutes police and engines from two firehouses arrived on the scene, and a large crowd gathered. Police, fearing further damage, cleared the area when electric sparks shot out of the hole. The fire itself quickly yielded to carbon dioxide fire extinguishers. Officials said the blast resulted from a short circuit which ignited gases in the manhole. Electric power was off for a two-hour period...
...slight defects or miscalculations can raise the pressure to the danger point. The rocket can explode if the nozzle is a few thousandths of an inch too small. A solid propellant may crack, sharply increasing the burning rate. Unburned propellant can block the nozzle, or flame can burn a hole in the thin casing. As any Cape Canaveral man knows, not even the pros can anticipate all possible ways for the rocket's restrained explosion to become unrestrained. Their motto: "Always assume that a rocket will explode...
Deep & Narrow. Before the war, even such well-known currents had not been thoroughly mapped in detail. For Woods Hole oceanographers, the first order of business was a new study of the great Gulf Stream, which exports tropical water to northern Europe. With the aid of loran, the new Atlantis surveys proved that it is not a wide, steady stream, but a jet that whips from side to side over hundreds of miles and sometimes curls into eddies. It may run fast or slow or backward, and only the general sum of its motion carries warm water to Europe...
Years of patient measurements of water temperature, salinity and density have begun to pay off by providing oceanography with a substructure of theory. Doubting the conventional view that ocean currents are simply streams of water pushed around by prevailing winds, Henry Stommel of Woods Hole analyzed thousands of such observations, predicted that a current would be found flowing under the Gulf Stream in the opposite direction. In 1957 the Atlantis and the British oceanographic ship Discovery II went looking for this current. Their tool was an ingenious buoy invented by British Oceanographer John C. Swallow, which sinks slowly until...
