Thanks H. I saw the site for Loch Lomond. I cannot believe there are only ten float planes based in the UK ( out of 28,000 planes in UK?) and half of them are on that Loch. We are an Island!
I am looking into this to find out why no one wants to do a floatplane/flying boat trip service. It cannot be uneconomical, people spend £30.00 flying a quarter of a mile in a helicopter for a few minutes.
