Use this version. Automobile and power companies are spending billions to make it real. There's a little bit of supersonic car in all of us.
Smart cars running on smart highways are but six years from prototype.
Feb 1996 Suppose that sometime this year two US airliners find themselves on a collision course. An air traffic controller relying on rapidly deteriorating 1960s-vintage equipment must distinguish the two planes from others on his radar screen and make a mental calculation about the likelihood of a crash. Though his radar display is two-dimensional, the controller must envision the planes' flight paths in three dimensions, then project the paths through time. He must take into account that, say, one plane is turning sharply and rapidly descending, while the other is slowly climbing. Alarmed, he'll quickly get on his radio to instruct one of the pilots to change course.
