...hurtles through outer space. Within the earth's atmosphere, it can be produced for brief intervals in a jet plane. To experience it, Cant took a 3½-hour pre-jet-flight physical, sat through four hours of indoctrination, spent an hour in the altitude chamber breathing oxygen under pressure, finally tried out an ejection seat (it hurled him 15 ft. into the air). After that he put on a flying suit, g suit and the rest of the gear to find out How to Go Weightless. See MEDICINE...
...opportunity to fly and fight alongside men like Obenauf that keeps most of us strapped into that oxygen mask...
...altitude gave the newsmen soroche -high-altitude sickness. Forced to run through crowds to keep up with Nixon, most came down with splitting headaches and failing memories. Hardest hit was Associated Press Photographer Henry Griffin, 46, who had to take deep draughts from a heavy oxygen tank he toted on his back. Cracked Griffin: "Let's get off this hill -I want to die breathing...
Atmosphere. The space capsule, like the pressure suit within it. will be pressurized at about 7½ Ibs. per sq. in. -the pressure normally found at 18,000 ft. Instead of ordinary air (21% oxygen), it will be filled with an artificial atmosphere containing at least 40% oxygen, to give the spaceman the same quantity of oxygen he would enjoy at sea level. During launching and reentry, the space pilot will have his pressure suit inflated. In relaxed, straightaway flight, he will be able to deflate his suit, open his visor and rely on cabin air. The air will...
...difficulties of food, drink and elimination snowball. Weight is the first, worst foe of the rocketeer trying to get a manned capsule into space, so everything that can possibly be saved and re-used must be conserved. Hence the futuristic proposals that in addition to recycling his oxygen supply (perhaps with elaborate photolysis, to break down the accumulating carbon dioxide), the space pilot will have to recycle his body wastes. Extraction of palatable water, though still not perfected, might be practicable for space flight if the equipment weight could be cut down. One suggestion for maintaining a near-perpetual cycle...
