Those of you who might have concluded that the risks posed by the Y2K Bug were overstated should take a look at this recent story about six Lockheed F-22 Raptors crossing the International Date Line (IDL). The F-22 Raptor might be the most advanced fighter jet in the world, but multiple systems, including fuel, navigation and communications, crashed when the six Raptors crossed the IDL. Fortunately the weather was good and there were refueling tankers around to help guide them home. Otherwise it would have been "real serious".
Clearly we haven't all learned the lessons from the Y2K experience.
