That logic is extremelly smart, I am analyzing like in Terminator 2 was that super intelligent robot arm

As I can see you also doing a name change during the fly, so the green airplane is 'plane1' in the first two frames, after a copy exactly to the same place but already as 'plane2'.
Moreover, removing for example the the 'Many' fills from 'plane2', anyway also for 'plane1' the same, it turns out that it is a group which is a circle. So I assume you use the rotate feature to follow the smooth fly.

Could you advise how you create this circle + airplane, I would think that the circle is transparent but seems no, having some fill. Briefly, I was not able to reproduce it
