Yes, indeed, because I thought there were others who went on the trip and were still not convinced. Honestly, if somehow a group could somehow penetrate a weak spot somewhere to journey to the ice wall and see what is really there.
Four flat earthers went on the trip: Jeran, Witsit, the gal and the film maker. Of the four, I believe all but Witsit went globe upon their return. Regarding Jeran being a shill, I have no idea as I never really looked at his work before or after. Witsit is still a geocentrist, however.
