To be fair, the experimental evidence presented in the wiki is a joke. "Is Kansas flatter than a pancake"? Really? The closest it comes to presenting a decent experiment is the BLE, which, when it was done properly, showed the Earth was round. There is some controversy in this community about that result, but none of that is actually pertaining to the set up and execution of the experiment, which we know, as a matter of record, was attested by Hampden's chosen referee as showing the Earth round. So I am not sure what experimental evidence Tausami could rely on so heavily as to discount the plethora of evidences for the Earth being round.
Sorry, but I just have to commend RS here. I've always loved the Kansas article for FES's stupidity for including it as evidence of FET. The study uses the USGS markers that calculate the distance of the point (on the surface) to the center of the Earth, which of course relies on the round shape of the Earth. Of course, even if an entire state were flat in the FET sense, it would hardly be evidence about the shape of the entire Earth. (Since an elephant's foot's bottom is flat, the elephant must be flat.) Good job, RS.
