...ever really turned the tide of a war, a cheery Scottish scientist named Sir Robert Alexander Watson-Watt* might claim to be the man. Sir Robert was the principal inventor of radar. The electronic watchdogs developed by him and his fellow "boffins" (secret war scientists) won the Battle of Britain for the outnumbered R.A.F. Sir Robert got a "well done"-the Order of the Bath...
...Radar ballooned in wartime into a great industry-and then collapsed just as suddenly. Few peacetime uses were found for military radars: they were not much help in navigating commercial airplanes or merchant vessels. They were also too costly, too complicated, and practically useless at very short range...

Panama. About 130 temporary bases were constructed outside the ten-mile-wide Canal Zone. Most of these bases (radar, searchlight, antiaircraft posts) have been returned to Panama. But the U.S. is faced with a terrific problem in defending the Big Ditch from the overcrowded air fields within the Canal Zone. Therefore, the U.S. has retained some of the outlying air bases, pointing out that though the fighting is over, the peace treaties have not been signed. Panama's President Enrique A. Jiménez has indicated that he understands the problem. But some Panamanians are piqued by the fact...
...Army, the Navy and the public. For the past year and a half the public had heard of the spectacular feats of the Army & Navy's G.C.A. (Ground Controlled Approach). It was relatively simple. The only equipment needed in the plane was an ordinary two-way radio. A radar unit on the field picked up the plane, radioed the pilot what course to fly at what speed, when to lose altitude and how much. Experienced crews brought the plane smack down the middle of the runway again & again in zero-zero conditions. Neither service considered it experimental. The Army...
