Drug smuggling: Underwater drones seized by Spanish police

Drug smuggling: Underwater drones seized by Spanish police - https://www.bbc.co.uk/news/world-europe-62040790 Jim Bell's comment:I actually thought of this 30+ years ago, unmanned, underwater smuggling drones, but I made no attempt to implement this. At that time, GPS was very new, solar cells were weak and relatively ineffective. I also figured that it could be an interesting hobby, minus the drugs of course. Whether this could get through the plastic trash, and 'ghost nets' I don't know.
