It's a beautiful clear day, I'm up in the Pentland Hills, 400 feet above see level, 190 miles to the East is Norway, whose highest westerly point should be around 8,000 feet and nothing lies in between, but I can't see it. There's no sea fog nor a cloud in the sky. Not with the naked eye, not with binoculars and not with a telescope. Explain it to me, without the kind of pseudoscience and gobbledegook present in your FAQ.
Speaking of clouds in the sky, why do uniformly dense layers of cloud appear to touch the horizon? If the Earth is flat, they should recede into the distance without ever coming into contact, visibly, with the Earth, much like a child's painting. If only high layers of Cirrus are present in the view, at a known height of around 10,000-25,000 ft, this picture should be impossible:

But there they are, touching the horizon.
And not like this:

As FES would have us think.
