Thanks for your feedback!
Yes, the drone had four separate "missions." We had to re-video the first segment because we began the turn too far to the east. This was done on a different morning; hence the difference in the lighting conditions.
The mission "coordinates" were uploaded to the drone using GPS. We followed by car, maintaining visual contact. The drone could fly 1 mile point to point; however, the curve in the first segment allowed the drone to fly a bit more than a mile (it was still a mile from the beginning point to the end point, as the crow flies).
Once the drone reached its end point for each segment, it hovered for a short time until my friend, the dronesman, took manual control and flew it a short distance back to us.
We gamed all of this out beforehand, of course.
