...blood might infect a pool given by 5,000 donors. Drs. Frank W. Hartman and George H. Mangun of Detroit's Henry Ford Hospital think they have found a way to sterilize the blood and kill the virus without making the blood harmful or useless. They have used nitrogen mustard, a war gas, and are now experimenting with a chemical called dimethyl sulphate. To prove the process safe, Dr. Hartman subjected himself to three transfusions. He felt all right afterward. Then he gave sterilized plasma to several hundred patients; none got jaundice (untreated blood that contains the virus causes...
...cockpit was barely big enough for him. Behind him, cramming most of the fuselage, were thick-walled tanks of "lox" (liquid oxygen) and alcohol. Tucked away in odd places, even under his feet, were heavy flasks of nitrogen gas compressed to 4,500 Ibs. a square inch. The windshield (of glass, rather than plastic, so it would not melt from air friction) was too small to give much visibility. From all sides, and above and below, a bristle of controls, dials and warning lights pressed on the pilot's seat...
...Piece. Silently and smoothly the X-1 cut away from the B29. For an instant it drove forward and downward. Then Chuck turned on the nitrogen pressure and fired the lox and alcohol in one of the rocket chambers. A spurt of white dots (visible shock waves) spurted out behind and grew into a long plumelike "contrail" (condensed water vapor...
When the fuel was gone (it lasts only 2½ minutes at full power), the X-1 slowed down and was back on the other side of sound's great wall. Chuck scavenged the last of the dangerous oxygen and alcohol from the system by flushing it with nitrogen. Then he began the long glide to earth, listening to the clock ticking on the instrument panel. He somehow found this "awful boring," he says, and welcomed his spurt of interest when he landed the X-1 at close to 165 miles an hour and rolled to a stop...
...smelled. But why they taste or smell the way they do is still unknown. The chemical characteristics of a compound may have little to do with its taste. Cane sugar (sucrose) contains only carbon, oxygen and hydrogen, but it tastes much like saccharin, whose quite different molecule has nitrogen and sulphur atoms...
