The very start of 2000 was problematic with many people fearing the consequences of a computer short-cut.
Journalling:
In the mid 1900s a cost cutting method of programming computers (leaving the 19 out of 1960 etc.) led to the Y2k issue.
This to some seemed like a serious threat.
Would planes fall from the sky?
Traffic lights stop working?
Some groups saw it as the coming of the Apocalyps - the End Time, the Rapture.
Fear mongering leading up to the event was rife and very worrying for some people, world-wide.
Then the year started with a whimper rather than a bang...
Only minor issues arose.
Certainly no earth shattering events and not a plane crash in sight!
