...flying a reconnaissance mission over the Sea of Japan, 50 miles off the North Korean coast, its electronic ears attuned to the radio and radar of the Communist half of the peninsula. Suddenly, two North Korean MIG-17 jet fighters flashed down. Though the U.S. plane was clearly over international waters and flying a course parallel to the Korean shore line, the Red jets opened fire with cannon and machine guns...
...spacecraft will be far more useful after they kick themselves into orbits close to the red planet. They will be able to study Mars for long periods at close range, sending back several kinds of maplike pictures, including intimate views of Mars made by infra-red light and by radar. A single orbiter will be able to chronicle an entire cycle of the Martian seasons, watching the growth of vegetation (if it really is vegetation) and mapping the fleeting details that were once interpreted as the famous Martian "canals," which are now thought to be optical illusions. It can measure...
...Edward Victor Appleton, 72, renowned British physicist and principal of Edinburgh University, who in 1924 proved that there were ionized layers in the upper atmosphere by bouncing short-length radio waves off them, a technique that made worldwide radio communication practicable, led directly to Britain's development of radar (thus giving the R.A.F. a crucial advantage over the numerically superior Luftwaffe), and won for the pioneering scientist the 1947 Nobel Prize in physics; of a stroke; in Edinburgh...
Orders from Abroad. Franco may never be considered respectable enough to be granted full membership in the Western community, but he has come a long way. As a de facto member of NATO, Spain last year was given full control of the former U.S. radar defense-warning system, has been promised F-104 fighter-bombers for its air force, plans to zip it up even further, with 70 new F-5 supersonic bombers-to be built in Spain under license from Northrop. Spain still stands in the Common Market waiting room, but it is busily spreading a net of trade...
...system designed to dispel such confusion began advanced tests last week. Arriving airplanes make their appearances on the Atlanta scope as the usual blips, which look very much alike, but planes participating in the test carry electronic transponders that send back a coded signal along with their radar echoes. A computer built into the intricate electronic system provides information for a luminous square of letters and numerals that appears on the scope beside the blip. Called an "alphanumeric data block," it identifies the airplane and gives its altitude, which the transponder gets automatically from the plane's altimeter...
