Did you know that if flying a noontime demo at a show for a manufacturer, or during the "here are the boys from (insert name here), your AMA liability insurance is void and you are personally 100% exposed to damages?
If it's just a "Here goes Boli and his Lightning" and I am not repping a product that is fine. If you are a team pilot, and displaying/demonstrating one of their products the AMA considers that flight to be a commercial Operation so your regular coverage is void and a separate policy is required.
