Planes fly about 6.8 miles above the earth.

Look at the pretty picture on the first page of this PDF:

https://sites.math.washington.edu/~conroy/m120-general/horizon.pdf

Hypotenuse: R+height of plane "h" = 3,900 + 6.8 = 3,906.8 miles Leg 1: R or 3,900 miles Leg 2: L (the variable we need to solve for, the visible distance to the horizon with a smooth globe shaped earth from a plane 6.8 miles up)

3,906.8 = √(L 2 + 3,900 2 ) Square both sides gives us... 15263086.24 = (L 2 + 3,900 2 ) We square 3,900 to get... 15263086.24 = (L 2 + 15210000) Subtracting 15210000 from both sides gives us... 53086.24 = L 2 Taking the square root of 53086.24 gives us... L = 230.404513844672757 miles

Do we even have anymore (((flat earthers))) on here?

Guess they just can't rotate a globe in their head.

He also thinks Hitler was controlled opposition, but thinks flat earth movement is legit. Sad.

It's sad to see. I've argued with him about jews as well.
