...relief flights that had been interrupted two weeks ago when federal troops started to fire on its planes. Together with flights chartered by Caritas, the international Catholic relief organization, the Biafran airlift brought to starving Biafrans some 30 tons of food and med icine per night-still only a fraction of the 1,000 tons a day that are needed. At week's end negotiators who have been meeting for four weeks in Addis Ababa made marked progress in clearing the logjam holding up large-scale relief. Meeting with Emperor Haile Selassie, moderator of the talks, they agreed...
...STOL and V/STOL rivals for interurban hops. The closest runner-up, Germany's Dornier Skyservant, seats only twelve; other STOL-type planes that have begun to enter the U.S. air-taxi/commuter business, like Canada's De Havilland Otter and the Helio Courier, have only a fraction of McDonnell Douglas' payload. Fully loaded, the plane can cruise at 250 m.p.h., land at speeds as slow as 55 m.p.h. on a 500-ft. runway; it can take off within 1,000 ft. (one-seventh the length of La Guardia's shortest shuttle runway...
...ship navigation. But bouncing radar waves off planets requires far more power and precision. For the Venus experiment, the Goldstone installation operated at 100,000 watts, twice the power of the largest U.S. commercial radio stations. When the signals came back 41 minutes later, they measured just a tiny fraction of a watt...
...much of a predictor, is a smart detective. It can usually reveal whether a heart has been damaged, and with these clues the cardiologist can prescribe care and treatment for patients who seem to run the greatest risks of heart attacks. Yet the electrocardiograph has identified only a fraction of the nation's ailing hearts...
...helpful in aligning jet-plane assembly operations and the two-mile-long Stanford linear accelerator. When the high energy of laser light is concentrated on a small area, it serves as a high-speed drill that can burn precision holes through materials as hard as diamonds in a small fraction of the time required by conventional methods. It can vaporize the rough edges of such microscopically small products as integrated circuits. A less powerful laser beam can weld wires and other delicate metallic parts without damaging nearby heat-sensitive parts...
