Tilting a 100-kw. high-frequency radar transmitter 71° into the night sky near Washington, D.C. last April 22, Gallet aimed a radar beam at what he believed to be a pipe that would carry the signal to a point in the South Pacific Ocean just off the southern tip of South America. Two-tenths of a second later, an echo came bounding back-after a round trip of 37,000 miles...
...eyes in bookstalls across Latin America are engaging editions of Spanish-language stories about happiness in Red China. Grownups can read more sophisticated magazines and drop in at 16 Red China-run "binational centers" set up in nine South American nations. They can tune to the powerful beam of Radio Peking, which recently jumped its broadcasts to 31½ hours a day in Spanish and Portuguese. Or they can simply turn to their daily papers, spotted with news from the New China News Agency, which often operates alongside Fidel Castro's mouthpiece Prensa Latina...
...rays are created by a quartz crystal, which converts electrical energy from an oscillator into mechanical vibrations in the air at a frequency of 1,000,000 cycles per second. A cone-shaped concentrator mechanically coupled to the crystal intensifies these vibrations and produces a sharply defined beam. The surgeon removes a small portion of the bone behind the ear, acoustically irradiates the exposed canal with the gun's waves. Much as a soprano's high note can shatter a wineglass, the beams shot from the gun are supposed to shake the diseased cell structure and destroy...
...stacking area over Preston check point, more than five miles south of Linden. As traffic moved, ARTC controllers directed the TWA plane to drop to 5,000 ft. and then, proceeding under control of La Guardia, to swing northeastward into the prescribed Instrument Landing System beam (ILS) to La Guardia's Runway 4 (see map). To the radar watchers the Connie appeared to be following the routine instructions...
...arranged in groups of three around the threshold of the runway. In front of each lamp is a filter with a red upper half and a clear lower half. In front of the filter is a two-inch horizontal slit. When an observer is above the center of the beam, the lamp looks white; in the middle it changes to pink, and in the lower half...
