Humm.....since i live in Europe, we don`t have a "aggressive" authority like in USA....however, it will be a matter of time, legislation came out also here...
In this case, quad`s + air planes fires, i think we should n`t use them because others plans fighting on lower altitudes...
We could however user our services with the fire-fighters, and give a new insight on the fires, if they accepted, of course...
However...
One day a notice a video, of a house burning and someone using a quad to record it. At certain part of the video, a fire-fight instead of concentrate of fight the fire, use the water to try to catch the quad...
My vision as a European, is of a great stupidity and immaturity....but, yey, im European and do not live in a "authority" "regime" like USA.....
Normally, here prevails the sense common.......
Sorry my bad English...
