The Y2K bug is a great illustration that a well-handled potential disaster looks like “nothing happened” in retrospect. The fact that Y2K seemed to be a non-event is a testament to how seriously people took this emergency, and how everyone buckled down and averted a worldwide infrastructure disaster.
I started working at Honeywell Aerospace (AlliedSignal back then) in 1998, and by that time people were already working on Y2K issues. We were in the GPS navigation business, and there were real issues that would have caused aircraft navigation to go awry unless they were fixed.
People buckled down, found the bugs, ran simulations, got FAA sign-offs, and deployed the fixes to all affected aircraft well before Y2K. Thanks to the effort, “nothing happened”.
