Why a filler?
I think that it is kind of unethical to use a "bus plunge" story as a filler, even if they had little or no technology. This accident is a tragedy however you look at it. I don't understand why it would be considered a filler anyway. If a bus does plunge over something, shouldn't it be considered a actual news story? I don't think it matters if it's happened so many times because don't robberies and murders occur all the time too? These make the news and I haven't heard of them being used as fillers. Maybe I'm missing something, but I really don't find anything humorous about bus plunge stories.
