Of course my "calculations" were half-baked -- I was merely illustrating just how very bad the luck was. There are VERY few people in the world that have access the actual facts of what happened -- everyone else, we're all just idly speculating. But do you really believe this event wasn't very bad luck if it was an accident? So sure, improbable things happen, but an improbable explanation is an improbable explanation. If you find every other explanation even more improbable, than go with that one. But don't dismiss other explanations as "silly" if the only explanation you got is improbable.
