Can I suggest a new category for drones?
Some years ago I upset a few on here predicting the escalation of cheap drones to replace a lot of UK police helicopter work..At that time a lot of expensive operations were conducted looking for missing persons, the majority who were later identified as having mental issues or later found dead.
These days every police force in the UK has a dedicated drone unit saving taxpayers a lot of money.
More importantly drones are now used for a large spectrum of aerial work
