Yesterday marked the third time in the past 18 years that a major air disaster has happened on 17 July.
TWA 800 on 17 July 1996
TAM 3054 on 17 July 2009
and now MH 17 on 17 July 2014.
It would be interesting to look at the statistical meaning (if any) of these accidents all happening on the same day of the year, as well as more general statistics of whether, for instance, air crashes are more likely in the summer months etc? The results could then also be sorted by cause, i.e. mechanical failure, human error, terrorism etc.
