Each working day, Los Angeles oil refineries and other processing plants spew out a mixture of gaseous wastes containing about 800 tons of sulphur dioxide. As it rises into the air, the sulphur dioxide combines with water vapor and oxygen to form sulphuric acid. The minuscule droplets pick up more water and a variety of solid particles (e.g., soot, dust), until the City of the Angels wears, instead of a halo, a hat of dirty grey smog...
...dead and apparently has been dead since she was last heard speaking." Kathy's body had been found just below the tunneled opening. Her knees were wedged against her chest. Kathy had fallen into a coma, and then died because her cramped body could not get enough oxygen. There was no pain in her face...
...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...
Chuck Yeager could not see much, but he had plenty to do. Swiftly he checked the instruments, tried the controls and adjusted his oxygen mask. Outside he could hear the thunder of the B-29's great engines and feel the vibration as the bomber climbed higher & higher. He felt it wheel on a turn, and heard Major Cardenas' voice on the radio: "Am turning on downwind leg at 21,000 ft." Then the bomber wheeled again. "Am turning on the base leg," said Major Cardenas. "Five minutes to drop time...
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...
