Lol, just because you never looked into FE doesnt mean you know its bullshit. Math dictates that earth would curve at about 8 inches per mile squared. So, from 39,000 feet, you should be able to see a more than 100 miles. And that would mean the curve that you should be able to observe would be more than a mile.

So, yes, if you have ever flown and not noticed a massive one mile curve in every direction, then you know the earth is flat. But, people are far too programmed to think anymore. At least here i have used basic math to prove FE is worth taking seriously
