I just read in the local Palo Alto Daily Post (P.7) that the National Guard is using a Predator Drone to relay live rimfire imagery to the firefighters in the Sierra Nevadas around Yosemite. The drone is operating out of Victorville airport in LA, which means it must fly up and down the Sierra Nevada range every day (22 hrs aloft max.). It must end up passing near Inyokern, Lone Pine, Bishop, etc. if it take a direct route.

Do these things pose a danger to gliders in that area? Do they fly only through MOAs? Is a TFR corridor established for transit? when they are going from point A to B, how hight do they like to fly them?
