One of the more effective "modern" ways to fight fire is with fire.... Firemen will do controlled burns, etc to remove fuel from a fire's path. The problem with fighting fires in the old days was they didn't have meteorology to tell them if rain was coming...or on the flipped side, wind. They also didn't have areal views of the region to really see destruction, beyond what you could see from fire towers. Most of the planes and choppers that drop water are only trying to redirect the fire, not totally extinguish it.
I remember a swamp tour I went on once where they talked about how the swamp caught fire from a lightning strike in the dry season. It's neat how fire can clear out brush, dead wood and plants and help new growth come back....it's part of nature on one level.... Sadly, California's winds and arid climates make it very deadly.
I remember driving through Florida years ago when wildfires were raging in the Northern part of the state. I drove down a 2 lane highway from Georgia to get into the state and bypassed the worst of the smoke.....(but it was still both inside and outside the car) I got gas at a station and you could taste the smoke in the air it was so heavy. We kept driving through to Orlando and Universal/Disney were virtually empty that week. I think they eventually got rain and it put out the fires, but that's what it takes to knock things back....
