In Dhahran, Saudi Arabia, on February 25, 1991, a Patriot missile failed to intercept an Iraqi Scud causing the death of 28 American soldiers.
The patriot missile system used floating point for time, so as uptime extended the clock became more and more granular, eventually to the point where time skipped so far that the range gate was tripped.
The fix was being deployed earlier that year but this unit hadn't been updated yet.
