An aspect of this tragedy which seem to have attracted few comments is the fact that the chain of events which led to the accidental activation of the seat began as a result of the aircraft being flown with one of the groin straps through the seat pan firing handle. Given the consequences in the event of an ejection, it is to be hoped that this is a highly unusual occurrence, but coupled with the ease with which the safety pin can be fitted incorrectly, it would place quite a premium on much greater care around entry and exit procedures.
