I'm trying to remember a historical incident I read about but have a foggy recollection of.
As far as I recall, during a religious holiday, a neighboring country launched an air strike against country X (was one of the countries Israel perhaps?) and inflicted severe damage because the victims were not able to launch planes due to religious prohibitions in effect during that day, similar to the activities prohibited during Sabbath (e.g. do not light fire).
I also have some vague recollection that the event occurred in October.
