About a year ago we had a drone operating on a fire that i was working. At the morning briefing the pilots were asked about drones and we all said "hell no". That afternoon they came back with a plan, they were going to have the drone operating overnight surveying, etc, and the drone pilots/operators turned up to see us to ask about weather conditions where they wanted to operate.
We all had a good chat with them and the next morning they showed us what they had produced overnight, very impressive. They also had a plan, along with our AAS and asked if they could operate over a set area of plantation forestry, and we just kept our flight paths clear of their operating area. It worked well, with both helicopters and drones operating in a similar "controlled" airspace. No problem.
However we had a plan, the drone operators had a flight plan, they had an aviation radio, and they even had a couple of spotters so that they could land the drone if a helicopter strayed into their airspace.
At no point did they try to get within 50m of a helicopter, and just being buzzing around helicopters without a plan!
