Scanning a moving blip on the screen that indicated an airliner, Japanese defense command radar operators on the northernmost tip of Hokkaido Island radioed a warning. "You are off course," chided the Japanese. "Turn south." But the message was lost amid crackling static, and Seaboard World Airlines Flight 25 3 A was already 80 nautical miles north of its course. Moments lat er, Pilot Joseph Tosolini was radioing that intercepting MIG fighters were forcing him to land on Iturup, one of the Soviet Kurile Islands. For Tosolini, 214 U.S. servicemen bound for Viet Nam aboard Flight 253A and the crew...
...experimenting with laser television for secret nighttime surveillance from aircraft, and military planners are developing bomb warheads that seek out targets illuminated by invisible infra-red laser beams. Peeling Potatoes. The various laser wave lengths, about 1,000 times shorter than those of the microwaves used in conventional radar, make laser altimeters, range finders and aerial mappers remarkably accurate. In a demonstration of a laser distance-measuring device, Spectra-Physics, Inc. flew the instrument over a Philadelphia high school stadium at an altitude of 1,000 ft. A conventional radar altimeter would have indicated only the slope of the stadium...
Sentinel's system of radar tracking stations, long-range Spartan missiles and short-range Sprint rockets could indeed be of some avail against Chinese intercontinental missiles, although Peking has fallen a year behind schedule and is not expected to pose any threat until the mid-1970s . Against the real and present peril of 780 land-based Soviet missiles already pointed at U.S. targets, however, Sentinel will afford virtually no protection. Even a "thick" ABM shield, costing $40 billion instead of the projected $5.5 billion for the thin screen, would be hopelessly porous. Missile experts are quicker to devise...
Opinion as to what had happened seesawed. Some officers thought it "highly probable" that a misreading of radar signals-images that looked like slow-moving helicopters but were really friendly vessels patrolling offshore-caused the allies to fire on their own ships. At week's end, while a special board of inquiry tried to fathom the mystery, U.S. officials in Saigon allowed that North Vietnamese helicopters might indeed have been in action in the DMZ. Whether or not they have come that far south, big Russian-built helicopters are now a standard part of North Viet...
...M.I.T. and Johns Hopkins, the only two academic entries on an otherwise corporation list, are among the top 100 because both institutions are involved in expensive applied research in such fields as Over-the-horizon radar, electromagnetic applications and military uses for the laser beam. M.I.T.'s contracts last year totaled $94.9 million, while Hopkins' amounted to $71.1 million...
