Hmm... an interesting one, but if you take as your starting point that Tain and Lossie are, in effect a package then it does lead towards a particular set of answers. But Tain and Lossie are in different local authority areas (Highland and Moray), and NIMBYs have never let mere rationality get in the way of a good campaign.
Having said that, as someone who has spent a fair chuck of an increasingly long lifetime well used to FJ noise, I was very struck on my last visit to Dornoch (and Bonar Bridge) by the fact that the noise of whatever was flying that day on the Tain range was very intrusive. Far more so than lviing near an operational base. It may be stating the obvious - but then the obvious is sometimes too easily missed - but has anyone looked at the detailed profiles of the operations at Tain to see if noise impact has been minimised?
