No matter what the incident, seems a shame that the show couldn't have been made the overriding priority
Surely you don't mean this? Not speculating on this particular incident, but would you really want a flying display to go on even if there were, for example, serious safety concerns etc?
Then there could be a discrete [sic] investigation
Playing devil's advocate for a moment, how do you know that the investigation hasn't already happened? And in this day and age, with Freedom of Information and press leaks etc, any investigation is hardly likely to be discreet! I'm not saying that this is a good thing, but it's true...
