IF the wind is in your face, then it is also blowing toward the crowd. In such a situation then going behind you is even more dangerous than with the wind in the other direction. If you can't understand why what you did is potentially dangerous, then I would be far happier for you not to be flying.

While I am sure that you were in full control at all times, things can go wrong. With only 20 feet between your plane and the crowd, and the wind blowing towards the crowd, it could turn nasty very quickly.
