airbosses must be certified to various show complexities and recertified annually.
That's reassuring!
the airshow business is high risk.
Yes, but does it
need to be high risk to accomplish the objective of presenting airplanes in flight to the interested public?
A learned friend of mine told me decades back: "No one ever died flying a normal circuit.". Although perhaps not 100% factual, he point was clear, fly a normal circuit, with normal separation, altitudes and speeds, and it's probably pretty safe. I think the aviation industry in general, and airshows at the point of that to the public, doesn't do itself any favours by having accidents - at all, much less those which were obviously human error. If "risky" elements need to be removed from an airshow routine to make it more safe, I feel that the safe, low risk demonstration should be the aspiration of every airshow participant.
