There is a water bomber over on Vancouver Island that is one of the largest in the world for fighting forest fires, it is used all over the world. I've seen the news media (believe what you want from this) talking with the owner and the maintenance costs and whatever he charges must be really high as they weren't using his plane for a fire last year or the year before when it was out of control. It wasn't for here, it was either Australia or Cali. If I had to guess, he probably charges close to a million just to get off the ground.
