...fixed topography; its changes are minute in time. But detecting the underwater enemy is the first job of Thach and his ASW team, and like the submariner, Thach faces the bewildering phenomenon of the sea itself: its lack of homogeneity, its massive motion, its madness, its strange, deep rivers. One undercurrent, recently discovered in the Pacific, is 200 miles wide, 500 to 1,000 ft. deep, flows east along the equator, 100 ft. below the westerly-flowing surface...
...perfect. Heavy seas, hammering the hull of a destroyer, can override the sonar-transmitted sounds of distant submarine screws or reduction gears. The sun heats the thin layer of air over smooth water, and this in turn can bend radar waves. Sometimes a thermal layer, 100 to 300 feet deep, distorts sound-and a knowledgeable sub skipper plays this layer like a shield. He can confound enemy sonar by hiding in the clacking wake of a destroyer, or by backing the submarine through his own wake to lose himself in his own echo...
...inertial navigation-a new means of finding latitude and longitude wholly without external reference points. Last week it was also used in the Arctic by the U.S.S. Skate, will go in even more sophisticated form into all the Navy's nuclear submarines, some of them designed to creep deep in enemy underwaters with the Polaris missile...
...were quickly run up to a simulated altitude of 38.000 ft., where the bends can be expected. They suffered none. Dr. Balke asked the men to do deep knee bends every three minutes (exercise speeds the onset of the bends, intensifies the pain). Still, most of them felt nothing. Physiologist Balke ordered five knee bends every two minutes. At this, most of the men felt twinges and began the descent to higher pressures...
Poitier), chained together at the wrist, are the only two to escape when a prison truck cracks up in a ditch. Linked but loathing, they stumble through swampland, nearly drown fording a river, nearly wrench their arms from their sockets clawing out of a deep clay pit. When they pause, it is not to rest but to spit forth their hatred. Telling Poitier why he is a "nigger," Curtis says: "It's like callin' a spade a spade. I'm a hunky. I don't try to argue out of it." Replies Actor Poitier: "You ever...
