Info from Licensor: "I Fly a 3DR Solo with a Gopro hero4.
I had flown my drone out to photograph a rail bridge. After I had taken the shots I wanted, I began recording video and flew home the drone. It flew within 2-300' of a tall light pole that had a hawk sitting on top of (I could not see it on the live view). A short time after that my video feed started spinning. I looked at where the drone had been and saw nothing. When I looked back at the screen I could see some leaves and snow. I grabbed my snowshoes and hiked out to try and find it. I searched the entire area along the railroad tracks for over an hour and only found it because the low battery alarm started beeping. After I replaced the props and batteries I took it on a few more successful flights that day."
