Meanwhile, La Guardia tower was following the Constellation on its radar, radioed one warning of "traffic at two-thirty, six miles northeast bound," and then another of "what appears to be jet traffic off your right now, 3 o'clock at one mile northeast bound." The only response from the Connie, after the second warning, was the sound of an open microphone; the rest was silence...
...totalitarian tyranny. The U.S. gave them freedom ? and in return they contributed their knowledge and disciplines to its science. World War II itself gave U.S. science its decisive impetus, for from the war came the tools and instruments that have made possible the scientific explosion. Out of wartime radar research grew the pure materials that later enabled William Shockley to develop the transistor. From the U.S.'s atomic bomb program came the cheap and plentiful radioactive tracers that have since transformed chemistry, biology and several other sciences. It is no coincidence that where the U.S. had only 15 Nobel...
...completed a device that proved he was correct. It was a maser, in which hopped-up ammonia molecules were made to serve as an atomic clock of unequaled accuracy. Since then, Townes's maser has been used to check Einstein's theory of relativity. It may soon revolutionize radar and open up new channels for communication. Townes is currently on leave from Columbia University to work at the Institute for Defense Analysis in Washington...
...Radar. FAA is working to eliminate the human element almost entirely and turn traffic control over to computers, is spending $200 million a year to develop an all-weather, electronically controlled system. Devices for the new system are already being developed and tested at FAA's experimental center at Atlantic City, NJ. One of the chief projects: three-dimensional radar, which, unlike present radar that shows only distance and bearing, will also show altitude. The FAA is testing an experimental 3-D radar apparatus, designed by New York's W. L. Maxson Corp., which picks up a target...
...airliners carry weather radar, but the sets show only the proximity of storms and not other aircraft. The FAA soon hopes to have an automatic, lightweight anticollision device that would warn approaching planes, as in the New York crash. One possibility: Bendix Corp. has developed a collision-avoidance system that bounces signals both off neighboring aircraft and off the ground to determine an approaching aircraft's course, tells the pilot what evasive action to take. The Sperry Rand Corp. is developing a system that uses high-frequency radio-wave techniques to detect the proximity of another aircraft; Motorola...
