I think we'll have to just disagree on this. My experience of seeing
helicopters flying in the mountains is that they look and sound like
insignificant insects from a distance. Close up they are noisy and
violent, but I always find it incredible how quickly the noise just
disappears after the drop off.

You're more than one????

Anyway, i live in a zone where heliflights are frequent and i can tell
you that's very very noisy: One helicopter is louder than the highway on
the ground of the valley ...
