Dangerous??!!
Captain Planet, collision is a consequence of motion and the airspace and aircraft type have little relevance to this fact! In fact flying VFR, Low Level and outside controlled airspace is peaceful bliss most of the time and completely the opposite when you go Class C as far as I'm concerned.
Flying floats anywhere in Europe for a decent salary is close to perfection and then Water Bombing during the summer would probably top that! But I'm sure there's some decent biz jet operators here too that give the same levels of satisfaction. The airlines I would be far from exhilarating these days but what-ever blows your hair back I guess!
