Bugs That Threaten the Life of People

In 1980, a faulty circuit in NORAD's computer system caused it to mistakenly conclude the US was under nuclear attack from the Soviet Union. The displays on NORAD systems showed seemingly random attacks and they didn't correspond with each other. And command posts around the US all had conflicting information which led leaders to conclude the whole thing was a regrettable computer error. In 1979 someone mistakenly inserted a training scenario into the computer system that made it seem like the Soviet Union had launched an all out nuclear attack on the US. But that wasn't a bug. That was a mistake on the part of a human who accidentally uploaded the wrong or rather executed the wrong command.
