Evidence for detection of high-energy cosmic gamma radiation (above 50 mev) from point source in constellation Sagittarius was reported in Nature. Case Western Reserve Univ. and Univ. of Melbourne (Australia) physicists presented preliminary results from collaborative program in which two high-altitude balloon flights were made from Parkes, Australia, Feb. 5-6 and Feb. 26-27. Object was first such point source of gamma rays detected in heavens. Research was supported by NASA, NSF, and Australian Research Grants Committee. (Frye et al."

Satellite system which combined navigational and air traffic control and collision prevention had been proposed to FAA and DOD by TRW Inc. Systems Group, Washington Evening Star reported. Proposal called for four satellites, one in permanent orbit with others revolving around it at lower altitudes. Aircraft would radio distinct signal to satellites and its position relative to two or more satellites would be determined by ground computers that could figure latitude and longitude of aircraft within 50 ft. System, based on delicate measurement of time for aircraft signals to reach satellite, would cost estimated $100 million, could be in operation by mid-1970s, and was also being proposed to aviation industry.
