WASHINGTON (AP) - Lights go out. Computers crash. Flights are delayed, baggage is lost. ATMs run out of cash,    cellular calls won't go through and cable TV is showing static. Sound like the nation's worst Y2K fears? In the    increasingly complex world of technology, those disasters can occur individually all in a day's work - whether or not    that day is the upcoming New Year's. Concerned that any technical failure in the earliest hours of Jan. 1 will be    blamed on the Year 2000 computer problem, the White House planned to release figures Monday showing how  often some systems typically break down. The move is precautionary, to avert public panic at first sign of a disruption in electricity or another essential service that may coincide with the date rollover but was not caused by the computer glitch.
