You need to find where it is first and be able to track it.

Finding it doesn't seem hard, it really seemed to try to get as much attention as possible.

And without being able to command it or GPS it shouldn't be hard to track it either.

In theory it could be following waypoints (no command frequency) and using ultrasonic "sonar" to avoid things like trees at low level. That's pretty difficult to track, especially if you're on the ground in an area with a lot of trees.

Sure, but extremely unlikely.

That's why radar was invented.
