I had a fly away last week on my second flight on top of a mountain with a Mavic 3 Pro. The drone was in cruise control and the controller screen went blank with no warning. The signal transmission bar were still all white at the time, no orange bars, no video distortion, no warning except the final drone disconnected message. RTH failed. The drone went down on a steep hillside in deep power snow. "Locate My Drone" worked fine. I hitch a ride with a passing snowmobile but failed in a rescue attempt on snowshoes. The snow was too deep and the terrain too steep. The area has had 300 inches of snow this season. I could never get closer than 200 feet to the drone. Linked is the fly log file and a low rez cache video file of the flight that I found on my RC Pro controller.
