Here is a drone in the forest...

<https://www.youtube.com/watch?v=h3vhlRBB9tg> Forest

We also obtain the trajectory in space: <https://skfb.ly/pxGqL>

It's interesting to note that this trajectory loops. That is to say,
the drone passes over the professional pilot's location, and is in
the same place at the end of the video.

This proves the quality of the trajectory estimation in space. :-)
