Or not - old aircraft spotter joke "It approached me at great speed till it disappeared over the horizon".

Really hard to tell when direction a plane is really headed in sometimes. So it can look like it made a 90 degree turn when it really didn't.

I had a drone get out of video range once, and I couldn't tell which way it was moving. I would rotate, then strafe left. I never was able to rotate it enough to clearly see any left or right movement relative to me, so eventually it auto-returned and crashed with 0% battery about 50' from where I launched it.

I should note it was either wind or microwaves that originallyl made it go out of video range, this was me trying to get an idea of flooding and hurricane damage the afternoon after hurricane Laura hit us.
