It feels so uncaring to think this but it seems like we can expect one or two fatals and several mishaps assoc with Osh each year.
I don't think it has a lot to do with the event itself - perhaps statistically no difference - but the sheer numbers of hours flown peaks then, so accidents do as well?
Although enough happen on approach & landing you might suspect distractions play a role. It can be overwhelming to the extent people might forget to FTA.
