This common condition, Menzel believes, is responsible for many of the saucer sightings (see diagram). The warm air overhead turns downward the light from bright objects, such as street lights or auto headlamps. If the "interface" is too turbulent, it can form no visible image, but if it is just steady enough, it will create bright images that seem to sweep rapidly across the dark sky. This is the explanation, says Menzel, for the famous "Lubbock Lights,"* which have been taken for interplanetary space ships flying in formation. They may be the images of a string of lights...
Then Menzel pointed a slender round beam of light from a projector at the underside of the invisible interface between the two liquids. Instead of passing through, the beam curved downward. When he looked directly into the downward slanting beam, he did not see a round spot of light. He saw an elliptical object, i.e., a perfect "flying saucer...
Once, years ago, when he still indulged in his favorite sport of mountain climbing, Alcide de Gasperi careered downward when his rope jammed. "I found myself dangling over the void," he said later. "For 20 minutes I could not move. People in the valley could see me just hanging there. Then I swung over to a ridge and I was safe." Italy's 71-year-old Prime Minister no longer climbs mountains, but his talent for hanging on has become one of the most awesome political feats of the postwar...
...musk ox is a hard animal to describe-it looks somewhat like a cross between a buffalo and an English sheep dog, has downward-curving horns and a morose expression. It is even harder to know. Though it once roamed as far south as Kentucky, it never learned to duck when hunters began shooting; now all but extinct, the musk ox lives on the fringe of the Arctic, where it munches lichen and other inferior fodder, and apparently spends a great deal of time watching it snow...
...Peter Bent Brigham Hospital, surgeons cut into her heart and enlarged the opening of its mitral valve. They anchored a small (½-in.) lucite ball on a steel suture just below the flaps of the valve. The plastic ball can move just enough to allow blood to drain downward into the ventricle. It moves up to act as a stopper in the mitral valve when the heart contracts to pump blood into the aorta...
