It's not just muppets and paramilitary now. Drones and delivery have been doing the rounds at a prison near everybody for years.
Weed delivery?
All very well to tell a 'foreign power' that you will shoot them down but another to achieve it without civilian casualties.
It does make a bit of sense for general deliveries because the current biped format has a serious issue with doors that do not open themselves. Much head scratching and yelling and that's the delivery muppets (From outer space).
