...past two decades has been performing a variety of delicate and complex corneal operations that he calls refractive keratoplasty (an operation on the cornea for optical reasons). In one procedure known as keratomileusis (cornea carving), the front of the cornea is sliced off with a high-speed vibrating blade, quickly frozen, and then reshaped on its underside by a lathe set by computer calculations. After thawing, the cornea slice is stitched back on the eye. To correct nearsightedness, the surgeon removes tissue from the center of the cornea, thereby flattening it. In farsighted patients, tissue is removed from the periphery...
...which is charged with border surveillance in the central sector at Fulda. "But we are forbidden to interfere until someone actually gets across the line. And we must make sure that we don't violate that line on patrol, not with a single footprint, tire track or rotor blade." Crow assigns daily helicopter patrols to fly "the trace," as the border is known, always with specially trained pilots. Ground patrols operate within a few feet of the frontier, occasionally augmented by new M-60A3 tanks, says Crow, "to remind the other side that we have a wartime capability here...
Beth Heiden's skates may be bronze, but her ten-speed is golden. At least that is the way it looked after the 20-year-old blade and bike speedster finished first in the women's world cycling championships in Sallanches, France. Beth, who placed third in the women's 3,000-meter speed-skating competition at the Lake Placid Winter Olympics, began bicycle racing only three summers ago, along with her quintuple-gold-medalist brother Eric, 22, as a way of keeping in condition for skating. Now she enjoys the sport as an end in itself...
...second helicopter, the crew set down in the desert because a warning light signaled that the chopper's 34-ft.-long rotor blade was in danger of failing. They discovered that it was cracked. The crew and all classified material were picked up by another helicopter...
Investigators suspect that the overheating in the first craft resulted from a cooling vent having been blocked by a crewman's flak jacket and bag. If so, that obviously was human error. The swirling sand, investigators say, could not have cracked the rotor blade in the second craft. The cause may never be known. The failure of the third chopper's pump also is a mystery and presumably could not have been caused by sand because the helicopters' hydraulic systems are well sealed...
