I found Ohlsdorf - as far as I know it is not an other word for ****. It is in Austria.
Ohlsdorf "Airport"
It is the "airport" of a modell airplane club. That guy did his stunt on a runway for radio controlled airplanes. That probably explains why the runway was smooth enough that nothing happend.
In the long run it will probably save lives if the FOCA of Austria revokes the license of that pilot.
