If you're considering joining the FE movement.
I have a couple things for you to consider.
Many FE videos on youtube use the distance squared times 8 inches to debunk the curvature, sphere thing.
They promote it as an equation accepted by RE that does not work on a round earth.
The reason it doesn't work on a round earth it is NOT an accepted formula.
Check this link out.

He is an Australian pilot, with a bunch of cameras, telescopes and some brains.
The reason I like his vid's is he does not use vulgarity or put downs.
I'm not a prude but endless put downs and name calling gets boring.
Also, there is little to no math involved.
Nor does he quote other "experts".
He sets up real time experiments and videos the results.
I'm not saying he is infallible but I was impressed with his attention to detail.
So, check out his vid's, they are worth a look.
Meanwhile, if there happens to be a FE pilot out there doing the same thing
Point me in that direction.
