"But there is point of interest (time/place/behaviour and so on) which was "overpassed""

That makes sense, it ties together the different meanings of this one.

I'm surprised that "она залетела" doesn't have some blame or judgement, or at least ridicule attached to it; usually slang language tries to pack as much punch as possible!

Are my translations here correct, btw?

"птица залетела в окно" the bird flew into the window (through the open window?
"птица налетела в окно" the bird flew into the window (closed window... и свернула себе шею?)

Thank you for your time Alex, it's appreciated as ever.
