...ordinary air traveler may get a glimpse of a control tower while taking off or landing: an area of greenish glass behind which moving figures are dimly visible. He may see radar antennas turning or catch a moment of radio chatter from the cockpit. He is comfortably aware that someone and something guides his plane, but he usually does not realize how vast and complicated that guidance process really is. To describe it in detail, TIME'S editors decided to use not only text but also ten pages of color photographs and maps, showing how a single flight...
...point to point along these invisible airways by means of electronic navigational aids that provide course, distance and location information. These "navaids" range from small location-marker beacons on the ground that light a bulb on the aircraft's instrument panel as it passes overhead, to huge, long-range radar systems that track aircraft and are linked to distant air-traffic control centers by microwave...
Back to the Shrimp Boats. Even while it evaluates these and other advanced air-traffic devices, the FAA has begun to install advanced radar traffic-control systems. Computerized alphanumeric systems are already in operation in air-traffic control centers in Atlanta, Jacksonville and New York, electronically printing the flight number, course and altitude next to the appropriate airliner blip on the radarscope. Eventually, FAA hopes to blanket U.S. airspace with alphanumeric coverage, providing a three-dimensional radar picture of all air traffic equipped with the necessary transponders...
...more effective ways to control aircraft flying under visual flight rules. In the meantime, the bulk of the burden must be borne by the 14,000 controllers in towers and control centers. By intensive training and concentration, these highly trained men have learned to control as many as 21 radar blips?each representing an airplane?at a time. They have learned to steel themselves against confusion and panic, no matter how extreme the emergency. They have developed an intense but quiet pride in their talents, their responsibility and their record...
...really hurt U.S. troops, but they are an effective harassment and, because they put the troops on the unaccustomed receiving line of heavy fire, a psychological advantage for the V.C. The Viet Cong cannot use aerial spotters to adjust their fire, of course, and are handicapped by American radar operators, who are quick to get a fix on their positions. Less than two minutes after last week's shelling of Danang, American batteries were blasting the Viet
