A heartening report in my local rag, the West Briton, last week. Can't locate the online version for a link, so I'll summarise.
A local horserider complained to St Keverne Parish Council (down The Lizard) that her horse had been spooked by a Merlin in the neighbourhood of Old Dean Quarry, which RNAS Culdrose uses as an approved site to practise confined area landings. Councillor Russell Hosken told the council "I feel this is a small inconvenience when we realise what the outcome of that training is", and Councillor Bill Frisken added "I wouldnt want to go too far on this one"
Nice to know that some in authority, admittedly at the lowest tier of government, realise that big noisy helicopters are there for a purpose, and not just to frighten the horses
