People being able to buy drones off the shelf with absolutely no aviation savvy and punching them up into airspace which contain manned aircraft is the crux of the problem. I’ve got a DJI Spark that’s supposedly got a 7km range, I can’t legally operate it beyond about 1km in order to keep it in visual sight, loss sight of it an I’m illegal and it then becomes potentially dangerous - forget all the rules.
Plenty of uneducated drones pilots have lost their $3000 toy by punching it up high then flying it BVLOS out a few Kms in a tailwind and then decided to hit return to home when the battery gets to 30%, only to find that the drone is punching into a strong headwind and lands or crashes in an unknown location! Not really smart! A PPL holder would be able to easily work this problem out. And we have uneducated people being able to buy one of these drones straight off the shelf and hit the airways. Bit like a 10 year old kid buying a car and driving it home....
