Suddenly a burst of fire hit the water just 16 ft. from the Neckar. Then a corvette struck the German craft with eight 30-mm shells, setting her stern gun turret afire and punching a hole in her hull beneath the waterline. Three crewmen were injured. After the fire was put out and the leak plugged, the Neckar limped into its home port of Kiel. To prevent damage to NATO-Warsaw Pact relations, Bonn described the attack as an accident, perhaps caused by the poor aim of Polish gunners. Warsaw began an investigation into the occurrence...
When Cordell Hull, F.D.R.'s Secretary of State, talked of the U.N. as a panacea for world problems, of bringing an end to the era of power politics, he could be forgiven because the U.N. did not yet exist...
...Monitor lies bottom up some 220 ft. below the surface, balanced on its cylindrical "cheesebox" turret. Since divers cannot work easily at that depth, scientists knew only that the ship's metal hull was corroded, but they did not know how badly. Indeed, the new data gathered on the Monitor < represent a significant advance in undersea research. "This is a prototype for marine archaeology," says NOAA Spokesman Dane Kanop. "We are writing the book...
...returned data from an array of cameras and sensors to shipboard computers and monitors. An acoustical locating system, accurate to within 20 in., will guide scientists in assembling a photomosaic of the more than 2,000 high-resolution still photographs the drone has taken of the ship's hull. In addition, a sonar scan will be used to make a false-color three-dimensional computer map of the Monitor...
...learn how fast sections of the hull are corroding, the drone poked "stab sensors" through encrusted sea life and rust and measured the electromagnetic field at the ship's surface. Reason: the Monitor's iron and steel combine with salt water to form a weak natural battery. The resulting electric current peels electrons from the hull, making it easier for oxygen atoms to attach themselves; oxidation, or rusting, ensues. To protect the Monitor while officials decide what to do, scientists may attach "sacrificial anodes" of zinc to the hull to divert the corrosion process away from the aging metal...
