Most people in the stadium would probably only hear the noise of the jets for a second or two and might (if lucky) catch a fleeting glimpse of the aircraft.
Nice idea to have a flypast in principle, but totally pointless to have one over an enclosed stadium which will take less than half a second to fly over.
Whilst I wouldn't agree with BM's tone, I'd agree it was a waste of time and not required for future matches as it adds nothing to the event.
If the RAF want a bit of
PR at such games, send their band or a drill team. At least the spectators might see something and relate to it.
