The video clip has been shown to be a fake, produced by a special effects worker, but it went viral.  It's cool, but not helpful.  It has now reinforced the idea in the minds of the general public that UAVs (we don't use the word 'drone'!) are dangerous.

Of course, UAVs in the wrong hands and used in the wrong environment can be dangerous.  New Zealand Civil Aviation Authority is currently writing new rules to cover the operation of RPAS.  This sort of thing is going to make the authorities around the world look even harder at controlling the operation of UAVs
