There were a lot of drone stands at this years Helitech in London and by drones I mean big stuff.I can envisage them taking over a lot of power line and pipe line inspections in the future.
The UK regulator is already looking at the future.

Police operations are already being scaled to meet the future.The days of wasting money on missing persons are now history with dedicated local drone operators used in much the same as dog units.
How much longer before the helicopters above London are replaced by drones?
