I totally disagree with that generalisation!
You have to admit that quite a few spectators go along just in the hope of witnessing something like this.
Sorry, but on the basis that aeroplane accidents at air shows are unlikely to be survivable, I vehemently disagree with that. There might be one or two sickos, as there always are in society, but to suggest that "quite a few" go in the hope of seeing someone killed is sick in itself!
