Russia's Beriev Be-200 is the only purpose-built jet-powered water-bomber in the world. Built originally as a general-purpose amphibian aircraft, it's come to be used almost exclusively in the fire-fighting role.
In 2010 several Be-200's were fighting a forest fire in Russia when one of the pilots noticed a house on fire nearby. He proceeded to make two passes, dumping 12 tons of water on the fire, the firefighters and a TV news crew. It certainly provided the camera crew an opportunity to film a water-bomber from a unique angle and perspective!
I bet some of the crews fighting wildfires out West right now would love to have a couple of squadrons of those Berievs at their beck and call . . .
