“To me, rotary-wing aircraft are the sky equivalent of mopeds on car-congested roads: they fly at speeds and trajectories (incl. vertical) that are so different from those of fixed-wing aircraft, that it's always challenging to separate them, especially visually (as is very often the case for low-altitude helicopter flights that operate VFR).”
