Don’t know about a show but there was a father who killed his son and closer to home on two tree island, the southend club, a guy flew his model into his face and was saved from death by another modeller who arrived at the field after the accident although the victim was blinded. Both were during low passes.
In the early helicopter days I would watch between cars but imho ducted fans followed by gas turbine powered scale jets which fly up to 200 mph are far more dangerous. I’ve seen a lot of crashes but far fewer compared to my brother who has french display licenses.
