Fatal aircraft accidents on Friday 13th – a statistical analysis
13 September 2013

Friday the 13th is considered an unlucky day in Western superstition. Does this bad luck translate to a higher number of aircraft accidents? No. On the contrary.

The Aviation Safety Network database contains all known fatal airliner accidents. An analysis of theses accidents shows that there have been a total of 2288 fatal airliner accidents on passenger flights from January 1, 1945 up to and including Friday 13 September 2013. This translates to an average of 0,091 fatal accidents per day.

In this period there were 118 ‘Friday 13th’ days during which eight fatal airliner accidents were recorded, an average of 0,067 per day.

Friday in itself does not appear to be a safer day compared to other days. Looking at a break down per calendar day, Friday seems like an average weekday.
