...like similar crews at 40 other bases, carefully nursed in-training plane crews on simulated flights into thin-air altitudes. A straight-A student in off-duty courses at the University of Arizona, Specialist Moore soon learned on his Air Force duty how altitude affects the human body. Without oxygen a man blacks out above 20,000 ft., suffers from expanding intestinal gas around 25,000, feels intolerable heart strain even with a high-pressure oxygen mask at 50,000, dies instantly from boiling blood (bubbling off gas like soda water) at 63,000 ft. if not pressurized inside...
...high-altitude chamber. On the control panel outside the 10-ft.-by-30-ft. heavy steel tank, he set the altitude indicator at 73,000 ft., a near vacuum just below the limit of the chamber's air seals. Not in space suit, but holding an oxygen mask, he let himself into the chamber and waited for the air pumps to lower the pressure, take him "up" past the blackout stage, on beyond the sure-death line to 73,000 ft. His body, as if taken by rocket to the edge of space, expanded in the vacuumlike atmosphere...
Ultrasonic machines are used for hospital and industrial cleaning and degreasing. They can join metals previously impossible to weld or solder, drill square and other odd-shaped holes in brittle materials, such as germanium and glass. They will measure any liquid, including exotic jet fuels, and liquid oxygen in rockets. The aircraft, electronic and missile makers have been a major spur to the growth of ultrasonics. Before the development of ultrasonic cleaners, jet-engine nozzles and oil filters had to be thrown away when dirty. Now imbedded residue can be removed in minutes through the use of sound energy...
Machines to bypass the heart and lungs during operations inside the heart vary widely because surgeons have pet preferences about details. Biggest difference is in how the blood is oxygenated: some machines bubble the oxygen through the blood, others spread the blood in a thin film over screens in an oxygen-filled chamber. Virtually all the machines are now driven by an electric motor pump, and many need a squad of physicians and technicians to keep an eye on them...
Probably it has no life at all. Dr. Kuiper thinks that it has no water or free oxygen. Radio waves, which penetrate the murky atmosphere, hint that the temperature of the invisible surface is something like 500° F., which is much too high for the earth's kinds of life. Venus rotates only once in several weeks, making the sunlit side much hotter than the dark side, and causing violent storms that sweep perpetually over its hot, dry deserts...
