I'd like to hear a lot more information about how they identify these drones. Are people really standing near these extremely dangerous, fast moving fires where they could be burned alive to fly their drones? Could be. People do dumb things. Is it pilots spotting drones or people on the ground? Most drones are going to be hard to spot from a moving plane in an area with smoke, wind, fire, flying debris, etc. Most planes are going to be going over 100mph. Stall speed + some margin for error. Unexpected small objects might be hard to correctly identify at this speed.
Do we have video or pictures of the suspect drones or only stories of people who saw one? I assume the drones are getting spectacular footage of these fires and uploading youtube. It would be nice to have links to the videos.
If they have all these drones in the fire areas, I assume they have caught some of the drone operators. There aren't going to be hoards of non-emergency personal in the area near a fire. A guy with a transmitter is going to stick out. He'd be easier to see than a small drone. He's bigger.
A lot of these fires are dangerous because of high winds. What where the winds of at the time the drones were spotted, and what is the upper limit at which a drone can be reasonably operated?
