If an airplane is going 600 miles per hour against the spin of the earth which is 2400 mph approximately and the air plane is 30k miles up in the air? How is a flight going some where against the spin then back is the same time?

And how does the spin of the earth affect an airplane 30k miles up in super thing air? What is transferring the movement from the ground to the super thing air 30k miles up?

So 2400 mph against the rotation at 30 k feet it wouldn't be insanely faster? Something is just is not adding up... it does not seem possible that 30k feet away from the spining earth it would effect an airplane still? Especially in the thinner atmosphere

Eratosthenes calculated the circumference of the earth in 240 BC. Even before Christ, people knew the earth was round. I used to have a quite powerful telescope and I physically saw Saturn and Jupiter. They were definitely round. The earth is not flat.

So how do you examine the math not adding up when people zoom in and see ships that should be well below the horizon? Or are those ideas just all made up hoaxes?

Not 100% sure what you are referring to, but I am assuming you are looking at an optical illusion. Kind of like on a hot day when you can see water on a road up ahead, but when you get closer it is completely dry.
