Fire departments are testing autonomous drones that fight wildfires before crews even arrive

This is a most excellent place for technology news and articles.
I feel like I read a few years back that aggressive suppression of wildfires leads to more and bigger fires.
The fuel piles up and eventually something sets it off, then there's no stopping it.
There's better/worse times to burn off excess vegetation and get the natural fire cycle restarted. During Santa Anas (hot dry strong winds) and drought, it would be better to quash a small fire quickly before it becomes several enormous ones. Then you could go back after some winter rains and set a controlled burn.
