Nice! Having some flying fun, I see.
FJB, you have a VERY nice camera in your phone, excellent quality, but remember, non-pilot here. are these the forest service planes that drop retardent or water?
I don't think they pick up water that way. I know the helicopters using large water buckets can do that but the planes would have to go back to their base to reload on water. There was an article some years back where a scuba diver in a lake got picked up by accident in a bucket for firefighting. It ended well but it was still interesting to read.
