...naval rifle. Since the Marines had already landed when McCoy's Navy showed up last April, the beach smashers had to learn to become pinpoint artillerists. It was no easy task. The spin-stabilized 5-in. rocket is not nearly so accurate as a naval rifle shell. Moreover, no one knew if the squat, underpowered ships could safely negotiate Viet Nam's tortuous Mekong River Delta-a prime necessity if their rockets' five-mile strike range was to be applied effectively against inland Viet Cong installations. Slowly but steadily, the rocket men overcame the built-in limitations...
...take a heavy toll of Red dead last week. The Marines, helpless and unreachable by their own medical corpsmen, were mercilessly slaughtered by North Vietnamese regulars. "During the night, the North Viets came," said one survivor of the massacre, a radio operator whose abdomen had been ripped by shell fragments. "They took my cigarettes and my watch, but they didn't shoot me. They must have looked at my spilled guts and figured I was dead. I was lucky...
...force of a single grain of salt dropped less than one-half of an inch. Then, at the NASA Ames research center in California, Rogallo overheard a cafeteria conversation between two biologists: How could they record the heartbeat of a six-day-old chick embryo without piercing the egg shell...
Rogallo made minor modifications in his dust detector, the biologists supplied the egg, and the unborn chick's heartbeat registered strongly through its unbroken shell. As proof, Rogallo exhibited the live and healthy chick of a bobwhite quail whose incubation had been monitored but undisturbed. And, said Dr. Hartwig proudly, the Food and Drug Administration is completing the space-to-chick-to-man cycle: it is using Rogallo's sensor to study the effects of drugs on the heart...
...archaeologists should have missed such a find for so long-the area lies beneath a well-traveled air route to Bogota. Even more humbling is the knowledge that these aboriginal people were sophisticated enough to turn their hostile environment to such advantage. According to carbon 14 dating of a shell mound near the area, the newly discovered culture goes back to 3090 B.C., making it the oldest pottery site recorded in the New World. Only within recent years has earth-moving equipment, mechanized farming and malaria control made a 20th century dent on the ridged plains of Colombia...
