I voted for number 3. Why ? Partly because there's no information as yet that the flight was legally sanctioned by the CAA as part of some film-making activities, indeed the fact the CAA are actively helping the search for the pilot indicates otherwise.
If someone undertakes risky behaviour, it's likely that they'll keep pushing the boundaries until the risk taken exceeds both their own, and the aircraft's abilities and they die. If they do that, I don't want to be near them when they do, and I'm sure that their passengers won't appreciate the extremely intense but very short adrenalin rush which will result.
