When computers were first being developed, they had a definite purpose--primarily military. Some were used in the development of complex arms calculations; others for satellite and radar. But today it seems that beyond speed, the purpose of further computer technology development is vacuous...
...pilot's path. CAT can be caused by a lot of things, including a change in direction of the jet stream, a clash of opposing air masses or a swirl of wind rising off a mountain. Not only is the phenomenon invisible, both to the eye and to radar, but it can also be highly localized, lurking in a patch of sky as small as 1,000 ft. across. When CAT hits, says retired United Airlines captain Andy D. Yates Jr., it is "like an anvil...
Currently, the best defense pilots have against such sky skids is an alert by other pilots up ahead who have just traversed a pool of unsteady air. But NASA and private industry may soon have a better way: they are designing a sort of infrared radar that would let planes scan the sky for agitated particles in the air characteristic of CAT. NASA plans to test the device next spring but does not know when it will be operational. In the meantime, the FAA is improving the pilot reporting system by equipping planes with software that measures even mild turbulence...
...while Charney suggested that Harvard may be trying to put together a Knafel Center plan to "slip underneath the radar," Mary Power, Harvard's director of community relations said that, like other community members, the University is concerned with the city's development patterns...
MISSION: High-altitude voyeurism. The reconnaissance plane collects multisensor photo, electro-optic, infrared and radar imagery--day or night and in all kinds of weather. It's been used to peek at everyone from Khrushchev to Castro to Ho Chi Minh, left. Among its more benign photo ops: floods, volcanoes and crops...
