Eager. Either way, the losses are equally disturbing. If the planes were lost because of malfunctions, what precisely went wrong? And if they were shot down, what happened to the planes' sophisticated protective gadgetry? In theory, the F-111 flies so fast and so low that radar cannot lock onto it and antiaircraft crews can hardly see it, let alone track...
...pilots also provided Hillenbrand with some plausible explanations for the mystery that surrounds every F-111 loss. The plane flies not only under enemy radar but too low to be tracked by American radar or by line-of-sight radio communications. That explains why no emergency messages have ever been received from an F-111 pilot before a combat crash. The planes also fly singly and at night, rather than in groups during daylight. Thus when they go down, there are no friendly witnesses. In fact, no one knows when an F-111 is missing until it fails to make...
That still does not explain why the planes crash in the first place. Although the F-111 was designed as an all-weather craft, some flyers speculate that dense rain squalls in Viet Nam somehow foil the plane's complex TFR (terrain-following radar), which permits it to skim treetops at 200 ft. above ground at speeds of more than 500 m.p.h. Others suggest that the dense tropical humidity in Southeast Asia somehow damages its complex electronic circuits governing flight and navigational controls. But no one really knows for sure. After returning from an F-111 mission over Laos...
...biologist-professor George Wald: "However horrifying and destructive, you can't think of anything so horrible that somebody would not feel elated at carrying it out." As a matter of fact, said Cornell Astronomer Carl Sagan, other civilizations may already know about us because of our high-frequency radar and military messages. "That," said Sagan, "may explain why nobody has been here...
...nonreligious Jews. "Perhaps," says Goren, "we can create a whole new atmosphere and build a bridge of love between the two communities of the population." When he was chief rabbi of the army, Goren found a way for Orthodox soldiers to drive jeeps or operate equipment such as radar on the Sabbath by pointing out the soldier's compelling duty to preserve Israel's security. In a like vein, says Goren,"if it is essential [for an Orthodox policeman] to control traffic on the Sabbath, then the way must be found to do it within Halakhah...
