"It is illegal to fly such a device without authorisation. The drone was reportedly flying higher than 200 feet (60 metres) "
Not really sure - they would have canceled the show if there was a stork flying "higher than 60m" ?
Why drones are special ?
(i'm not endorsing what he did , don't fly anything near air traffic should be common knowledge to any RC operator )
Another question
Would THIS "camera drone"
