I'm starting to doubt his observations, only because after 150 years so many damn questions are unanswered, and there are so many inconsistencies that seem to work just fine with a RE.
Rowbotham was a hypocrite. Rallying against the dogma of a round earth, then basing 75% of his own work on baseless conjecture and often superstition. He was a hypocrite and anybody putting all his faith in that book, or claiming to put all his faith in that book, is a hypocrite too.
Yes, I'm talking to you, Tom. You've been shown all the reasons why Rowbotham cannot possibly be correct, and instead of trying to give a reasonable rebuttal, you blindly quote dogma, ignorantly saying "Read the book". Dogma. That's all "Earth Not a Globe" is, and that's all "Dr" Rowbotham was good for. This is proven by you time and time again when you tell people to read the book; you can't back what he says up with any other source (except the other dogmatic, Christian fundamentalist FEers who claimed to have conducted their own experiments proving him right). This lack of corroboration is the reason why FET is taken as a joke.
The difference between you and TheEngineer is that rather than copy pasting the same ridiculous shit over and over again, he actually tries to come up with reasonable explanations for the bullshit Rowbotham obviously got wrong.
Whether you can trust Rowbotham's experiments or not, everything he did beyond "proving" the earth to be flat was not based on experiment. It's based on conjecture. It's silly dogma, all of it, and you look like a fool for constantly backing it up.
