...mere 30 miles north of Saigon. In the hope of avoiding a disaster like the one fortnight ago at nearby Dongxoai (rhymes with wrong's why), U.S. planners in Saigon searched for a means to trap the concealed Communist troops by surprise in their jungle hideout. SAC had long been restless to get into the war, and General William C. Westmoreland, commander of U.S. forces in South Viet Nam, gave SAC its wish. The big bombers would unroll a carpet of destruction, carefully tacked down by radar-controlled bombsights guaranteed to produce pinpoint accuracy. The plan was approved...
...hindsight, use of the B-52s had been an expensive means of hunting guerrillas, and the scheme's only real merit may well have been psychological. Hanoi could hardly fail to notice how quickly and easily SAC's huge squadrons had been brought into the Viet Nam battle. The B-52s would, of course, be enormously effective if turned onto the cities or factories of the north. But the jungle strike also served to prove once again that the war in South Viet Nam can be won only by foot soldiers, closely supported by tactical air strikes...
...they have had close calls with two patients. A man of 68 had been doing well in Dunedin Hospital after a week on an external pacemaker. The surgeons were installing an internal model that was designed to work indefinitely, but when they cut into the patient's heart sac to put an electrode in the heart muscle, the external pacemaker went wild, and the heart twitched ineffectively. The doctors traced the trouble to high-frequency interference from the diathermy machine that powered the electric scalpel they were using.

...highly successful experiment with a unit that replaced both of a dog's ventricles. Yet progress in the field is so fast that within four days the researchers were dismissing their test as old hat. They were getting as good or better results with a single ballooning sac inserted in the left ventricle alone. It seems, says Dr. Hall, that this may be enough in many cases to stimulate, if not precisely duplicate, the work of nature's complex four-chambered heart...
...more ominous, the recipient had a number of severe congenital abnormalities. These had led to repeated urinary-tract infections, and caused in turn, congestive heart failure, high blood pressure, and the formation of kidney stones. Now, on top of everything else, he had anemia and inflammation of the heart sac...
