"setting Back the Campaign!"
Last week we had a Chinook (sounded like, but it was late and dark), low level over Putney which actually made the windows shudder (not simply rattle) - just what 'Angry of Putney' needs in the way of ammunition - children awakened, dogs barking, prize chickens laying eggs (ok so maybe that's over egging it (!) but I many moons ago I lived near the ranges on Salisbury Plane and the local smallholders used to complain of exactly that during low level ops (usually blaming the poor folks at ETPS)) etc etc etc. Generally though, over 8 years of living under the route, the baby helos are pretty well behaved and their buzz is less intrusive than the shock wave from the heavy blades (at (cough) 500ft...??!!).
