Great summing up Tony - Thanks ... I fly in the UK, but I'm interested in this because it seems the CAA are following FAA guidance pretty closely in regard to sUAV operation on this side of the pond.
There are a few 'diamonds in the rough' here though I think ... 12 days is an extremely short sample period, so it would be unprecedented to use this report as a keystone in future legislation. But saying that, it showcases not only the few 'idiots' flying on runway approach paths and at crazy heights, but it does highlight a large population of users who are flying in a restricted way - which must be frustrating for them - and shows that there are a lot of folks out there who ['may'] know the rules and are trying to fly safely - even though they know that doing their hobby is bending those rules.
Also - it's a bit alarmist - in that I don't know of anybody who upon seeing a banner-towing light a/c coming at where there drone was, wouldn't head for the deck! I'd be a lot more worried if during the 12 days of the research there was a near miss or two - But playing devil's advocate - maybe a lot of this report is showing that the majority of Drone operators are aware of Civil Aviation needs and in general, operate in ways to maintain clearance?
It would also be useful to note how many of those 6,117 'sightings of potentially unsafe use' between 2014 and 2018 took place in that Daytona Beach area - as you could look at it another way and say "Despite the high use of Drones in this area, there are very few near misses and collisions with Civil Aviation ..."
This also highlights how the DJI Aeroscope could be used to 'police' the air in an area like this, and identify those idiots that
are bringing us into disrepute. That might be the way to get public confidence back ...
