Good vibrations
Can the experts help me?
I live near an old helicopter low fly area south of Cambridge and we get all sorts
along there, Apaches, the odd Merlin etc etc and Chinooks.
we also have lots of bl**dy feral pigeons which scatter in panic but only when there is a Chinook in the area
it has always been so and my question is it a characteristic of the blades or the engines together which create some high Frequency harmonics which only seem to panic pigeons.if so l’d like to bottle and sell it!,
okay I’ll get my coat now!
