After centuries of living 2½ miles or so above sea level, says Dr. Monge, the Andean native has become "a climato-physiological variety of the human race." To cope with the low oxygen supply in the air he breathes, the typical inhabitant of the high Central Andes (including parts of Peru, Bolivia and Ecuador) has developed a barrel chest with extra lung capacity. He carries about two quarts more blood than the coastal Peruvian, about half again as much hemoglobin (the blood's oxygen-carrying component). His heart rate is slow and steady. "An ideal heart...
...perform amazing quantities of work at altitudes where non-adapted lowlanders fall gasping and retching. The somber-eyed, long-exploited descendant of the Incas is in fact a sort of superman. "After eight hours' hard work in mines at more than 16,000 feet above sea level," says Dr. Monge, "his idea of relaxation is a soccer match in which he sometimes plays barefooted...
...mines, or moved to coastal cities. When he descends to the Pacific, it becomes his turn to undergo the rigors of adaptation, and the experience is often too much for him. Partly for this reason, Lima and Callao have one of the world's highest T.B. rates. Dr. Monge thinks Andean man's future is in the mountains. There, with food, soap and some books, says Monge, he might one day recapture the creative vigor of the Incas...
...properly professional manner-they are apt to think about rockets, whose limit is above the sky. Last week a Manhattan meeting of the American Society of Mechanical Engineers heard Professor Hsue-shen Tsien, Chinese-born rocket expert from Caltech, on the prospects in rocketeering. Most of Dr. Tsien's paper was technical, e.g., how to keep the walls of combustion chambers from melting. But his conclusion was clear and startling: present-day technology is capable of building a transcontinental rocket ship...
...Dr. Tsien's rocket liner would be 78.9 ft. long and 8.86 ft. in diameter, with a loaded weight of 96,500 Ibs. It would have small wings and a ramjet as well as a rocket motor. Its maximum speed, 9,140 m.p.h., would carry the ship 1,200 miles on an elliptical course outside the atmosphere. As it curved down toward the earth, it would meet the air again and turn into a non-powered glider. Coasting through the air for another 1,800 miles, it would land at 150 m.p.h.-not much more than the landing speed...
