If you were flying the drone there in the approved space - you'd obviously know your drone was struck. Shouldnt that person have reported it immediately if they were being proper about following all guidelines?
Or as the promoter of the airshow permitting drones to be used, I'd be calling every single one of them in to show me their drone and all footage acquired during the event. Any one of them raising a stink about it, I'd be providing their contact information to the authorities.
