That's a very good question! I guess (depending on where in the tree it ended up) I would try using another drone to retrieve it.
Maybe that's a service I should entertain adding to my other services, Drone Search and Rescue LOL
It would be...
I think I know what happened after looking at the altitude in the image data vs the flight log on the video. I accidentally lowered the drone while clicking the C1 button to create the waypoint. I feel blessed that I didn't crash it into the tree...
It seems from the video thru the fog that the trees in the background are at a higher elevation but due to the fog that’s hard to see. That was my first impression.
Very good save.
