You have to be licensed to fly an airplane. You have to log a flight plan. I'm not an expert in aviation but I imagine if your flight plan includes something excessively risky that endangers the lives of yourself or others, someone is going to question it.

Flight plans are essentially like driving directions, just a bit more involved. They don’t however include things like “I plan to do barrel rolls”, or “I’m going to fly inverted”, or “I’m going to bank beyond the limits of my air frame and possibly sheer off the wings”, the risky/stupid equivalent to what this guy did.
