...remaining virtually silent on the matter for almost two days, the Soviet Union finally issued a labored account of an "unidentified plane" that had "rudely violated the state border and intruded deep into the Soviet Union's airspace." TASS admitted that Soviet interceptors had "fired warning shots and tracer shells along the flying route of the plane," but refused to acknowledge shooting it down...
...consider. The story, when finally told, of how the Israelis adapted their E-2C Hawkeye surveillance planes to take out the Syrian MiGs is bound to enter national legend. Descriptions of what the new equipment can do are spellbinding: ECMs, HUDs, jamming and antijamming devices; "smart" bombs and "tracer lines." So graceful are the arcs on the maps, so precise the computers, it is mortifying to note how easily one gets caught up in such things, thereby forgetting (perhaps conveniently) that their consequences are thousands dead, tens of thousands homeless...
...first step. A native of Johannesburg, South Africa, he became intrigued in 1956 by the difficulty doctors had in obtaining X-ray pictures of the brain. Because the cranium is so thick, they could make an X-ray beam "see" an abnormality only by injecting a patient with tracer dyes or air bubbles. When Cormack immigrated to the U.S. that year (he became an American citizen a decade later), he began exploring the physics of how X rays pass through differing body parts. Dividing this passage into cross-sectional slices, he found he could calculate the absorption...
...keys in a lock. A blood sample from a patient is added to a tube containing animal brain tissue and a radioactively tagged chemical known to bind to particular receptors. Whatever drug is in the patient's blood displaces the test chemical at these sites, and the radioactive tracer left behind can easily be measured, giving doctors a precise indication of the levels of the prescribed drug in the blood-and thus a firm indication of how the body is utilizing...
...particular skip tracer of this film is one John Collins, Vancouver's finest, Man of the Year for his firm three years running, and probably the coldest, most calculating lead character of the year. With his stylish suits and grown-out crew cut, he is the epitome of the emotionless bureaucrat, a surly, cocky SOB whose meanness is matched only by his ruthless efficiency (pardon me, I'm raving). He'll follow you around town, visit you at work, call you on the phone. Not that he doesn't have his own standards--pay up and it's all buddy...
