So read the headlines of page 13 of the Thursday Daily Mail.

It began; 'for most people, a trip to Antarctica would be a once-in-a-lifetime experience, a chance to see one of the most breathtaking landscapes on the planet. But early next year there could be a journey to the bottom of the Earth with a very different purpose. Its mission could not be more startling: to prove the Earth is Flat. Forget those millennia of geographical research and those millions of photographs from space of our globe-shaped planet. There really are people who think the world is shaped more like a disc than a ball-encircled by a massive perimeter of ice that's 45 metres thick and 50 metres high. "Beyond the ice wall is anyone's guess," says the website of the Flat Earth Society. "How far the ice extends, how it terminates, and what exists beyond it, are questions to which no present human experience can reply." With their trip down south, the flat-earthers hope to answer this. What's extraordinary about flat-earth theorists is that they maintain their belief despite the testimony of more than 550 humans who have gone into space.

'Does this mean today's flat-Earthers are Christian fundamentalists, too?' 'They are a whole mix of people' says Michael Marshall.

The article goes on with lots of very interesting facts etc. It gets more interesting when it tells us: 'The most cited [evidence] is the Bedford Level experiment carried out in 1838 by inventor samuel Roebotham. It was set up on a straight 9.5km stretch of the Bedford river, some of the flatest areas of England.Rowbottom stood in the river as a colleague rowed a boat away from him which was fitted with a flag raised 90cm above the water.........he could still see the flag after it had travelled 9.5km. According to his calculations based on the curvature of the Earth the top of the flag should have dropped out of sight, and be invisable through his telescope. But it wass still invisible.... The world was flat.'

'Unfortunately he failed to account for refraction, whereby lighty rays shift direction when passing through an atmosphere. As any surveyer will tell you, near the surface of the Earth, light rays often bend down, with the curve of the rays nearly matching the curvature of the earth.' 

"The flat-Earth Cruise," according to the programme of this year's FEIC programme, is due to set sail next year.'

There is more of the usual but I have recorded the important bits. So, flat-earthers on CIF, are any of you going or thinking of going on this trip? It really could be the beginning or end of the theory. No doubt youy will let us all know.

I am very surprised that CIF flat-Earthers have avoided commenting on this newspaper article. If it is true it could prove the earth is a flat disc. Moreover, in this article above it explains why boats do not dissappear over the horizon. As I recall dozens of such illustrations were put up on CIF for ages as proof that the Earth is flat. If it doesn't, has the theory any other facts to support it?

Ok, so I googled and found it.

If you read the article, it clearly explains flat-earthers beliefs and the nature of the cruise: it is NOT a trip to traverse across the ice, it is a trip to sail along the perimeter of the ice wall.

Jay Decasby, a prominent flat-earther who is sure of the trip’s success.
He told Forbes magazine: ‘All we have to do to shut this debate down once and for all is get the distance of the coast of Antarctica. If we can sail all the way around it, we will . . . prove it’s the outer edges of flat earth and refute entirely every single argument anyone can possibly try to pitch for the sun-worshipping cult of heliocentrism [a belief that the Sun is at the centre of the universe].’ 

If the model of earth is as depicted in most flat earth maps, the ice wall would be an exceedingly LONG distance around: much, much greater than the accepted heliocentric model of 25K miles in circuмference.

I believe it was Captain Cook who clocked it at 62K miles in 1773. That distance, 62K miles, is not possible if earth is a globe.
