The comparison has been made between road traffic accidents and the shoreham incident. The point has been made that the casualties were not participants. I would point out that the emphasis in road transport has been to make the process safer. Cars are very much less lethal. I contend, as latterly did Ralph Nader, that the safer the cars, the greater the number of pedestrian casualties. So, I guess that the attrition rate for non participants in road transport is not a good example for the argument against air shows. I'm sorry if this a non sequitur but the toing and froing in this thread is mind numbing.
All I know is that I was near a group of very experienced pilots who seemed to suck in their breath as the hunter reached the top of his manoeuvre. I have no FJ experience to speak of.
