Hi Frank
I remember walking the crowd line at one of the Don airshows whilst a fighter did it's turn overhead with it's afterburner on. The noise brought tears to my eyes,literally,and the reaction of the mothers and children along the line was worse, with lots of crying and howling,etc. A large wave of people set off away from the fence, at once, leading to a bit of a crowd-control incident.It soon passed but it was unpleasant, to say the least.Personally,I prefer the sound of a big radial or a Merlin, but that's just me.
regards
