I agree that they should have never stopped where they did (But) what if they had broken down in the same situation. Somethings happen that are uncontrollable like Motor quitting spinning a prop. Are the person involved at fault for stopping or shutting down. You can't say that it won't happen to me but if you are blasting off in a tournament it could and did happen to me once on clear lake years ago, I lost all power after taking off, Fortunately the guys behind me weren't that close and we were up waving a towel.
