...eastbound Stockholm was holding to the northern edge. On a clear night the course holds no serious hazard. But for three days fog had covered the sea from Newfoundland's banks down to Nantucket. The view from a ship's bridge was scarcely farther than the bow. Radar sets searched the seas ahead, but longtime masters with tight schedules reduced speed only slightly for foul weather...
Balancing Saga. At week's end insurance syndicates reckoned their shares of the multimillion dollar loss, radar experts considered electronic failure against human failure, architects tried to explain why the compartmented Andrea Doria sank. In the U.S. an adjourning Congress, without determining its questionable right to act. authorized an investigation of the sinking. Overseas, Italians and Swedes bitterly blamed one another for the loss. Meanwhile, grimmer figures were being figured. The weekend total: 25 dead...
...weathermen, radar has been the biggest boon their science has known since the barometer. Without radar, weather forecasters had to depend on reports from observation stations, which are always too few, and often slow to arrive. With radar, they can actually watch the approach of storm clouds. Many a weather or storm disaster might have been averted or minimized if proper radars had been on the job to flash a timely warning...

...Weather radar works by sending out pulses of radio waves which are reflected by raindrops, hailstones and other precipitation particles. Shorter waves rebound from the tiny drops of moisture of a cloud's surface. The longer wave bands penetrate clouds like X rays, show only the inner core (if any) of heavy rain or hail.- Thus, by varying wave bands and pulse lengths, the new weather radars can look at a cloud as a whole or can look deeply into it, or even through it. They can measure accurately a cloud's altitude -a matter of critical importance...
