Well, actually, yes, it was indeed their tragic bad luck that the aircraft hit the A27 as it did. If it had either undershot or overshot the road at that point, probably only the pilot would have been killed: still a tragedy, but (sadly) like many other air show crashes. Perhaps there was only about a couple of hundred metres in it, between one potential outcome and the other. If the pilot had been the only casualty, the AAIB would have investigated just the same, and hopefully lessons would have been learned just the same, but there wouldn't have been anything like the same ongoing ballyhoo, and probably not a 48-page thread here.
Somehow I cannot believe that that will be the verdict of the Coroner.
No, nor can I. Some things cannot be said.
