Around the Pitons, St Lucia.
Did my first long waypoint mission with Litchi yesterday. As I was prepared for, I lost signal as the drone passed Gros Piton (mountain). It made a great video though, clip of below (will process the full res stuff when back from holiday):
However I used the “reverse” at mission end option expecting it to retrace its steps, back around the mountain. It turns out that isn’t what that does, so I believe it just hovered for a while, before initiating low battery return to home. I am amazed that I got the drone back, and am very impressed with the collision avoidance as it came straight back over the mountain - scary footage here:
