If you're interested and or bored, take some time to watch this video. It's very convincing.
He's fundamentally wrong about everything he said. I'm not a physicist but I'll try to refute his BS.
1. He said that airplanes give you a experience of flying above a flat earthThe amosphere is spinning too, that gives you the feeling of being on a flat earth.
It's akin to watching an insect floating around in a moving car, to you the insect may look static, but to an outside observer the insect is moving at the same speed as the car. That's because the air inside the car is moving with you. The same goes for Earth and the atmosphere.
2. He said that starts should make all kinds of weird movements in the skyStars are so far away that even they're moving at high speeds, it takes them really really long to be out our sight, and that's because our angle of vision.
Consider a car and an airplane passing in front of you, even thou the plane is moving way faster, it takes it longer to be out of your angle of vision. The same applies to stars.
3. He made an example with the curvature of earth as 8 inches per mile squaredThis doesn't make any sense. The curvature is roughly 8 inches per mile, not mile squared. How do you workout curvature as inches/mile squared
So, the curvature of earth at 5 miles should be: 5 miles x 8 inches/mile = 40 inches
LOL at his calculation, he said 5 x 5 x 8 = 200 inches. Not only he's predicting a value 5 times higher, but he didn't even use his own formula.
By his claim, the calculation should've been
8 inch/miles squared x 5 miles = 40 inches/
milesOf course, that is also wrong, in fact, makes no sense. This is high school mathematics.
I stopped there. He's an idiot, so you are.
Hope this helps.
