If the air is moving with the Earth
and the plane is moving with the earth
the relative velocity of the air to the plane is 0. Of course there are other factors that move air, so some relative velocity to the plane is present, but certainly not enough to justify your position.


If the air is moving IN THE EXACT DIRECTION of the Earth, airplanes travelling though the air in the opposite direction to earth movement would need to account for overcoming this huge force that should be there
Of course it is not there, because the earth is not moving.

No they don't.
They only need enough so that their relative velocity to the earth is sufficient in the other direction.
This is pre PHY101 stuff.

So if you fly a in a hot air balloon for a 4 hours and the earth is really spinning at 1000mph - why dont you travel 4000miles?


Because the hot air balloon is also spinning at 1000 mph. And everything around it (including the air) is spinning at 1000 mph. But because everything is spinning at the same speed, everything ends up moving together and not hitting each other.
Pretend that the Earth's surface and the atmosphere are like two trains that are running side by side, at exactly the same speed. Even though both are moving very very fast, when you sit on either of the trains and look at the other it will appear to not be moving at all.
An airplane is like a person who's sitting on one train initially (the ground) and then takes off by jumping to the other train. Because the trains are moving at the same speed, he can easily make the jump, it will be like jumping from one stationary object to another. Relative to each other, the trains ARE stationary.
Now he starts running through the train at 10 mph. This is like an airplane running through the air. Amazingly, the person doesn't suddenly get smacked by the train he jumped on to. He's still perfectly OK, and relative to the first train he's moving at 10 mph. But relative to something that's NOT on the trains, he's moving very very quickly because the train he's on is moving very very quickly. So even though our train is flying through space at 50,000 mph, we can still move back and forth at much slower speeds and everything's OK.

Any physics u reference is just a conspiracy man. I think you're beginning to see he won't argue on your terms.

He doesn't have to, I guess :(
but I hope that he will research some of these things, understand them, and find that the evidence for them is outrageously compelling.
if not, w/e :(

I think you're missing my point. He Won't ever research your sources because he believes they are all part of a worldwide conspiracy to keep the secret of a flat earth. That Illogical thought forms his position. The rubuttals he's giving are more to convince himself than anyone else

A balloon has a very high surface area, thus as the air is carried with the earth, the balloon is carried with the air.
then, the previously mentioned relative velocity of the air to the earth is used for actual transportation relative to the earth


So if the earth is traveling at 500,000 mph though the milky way and its gravity is sucking the air to it so that it is also traveling at 500,000 mph in the exact same relative direction and air has a mass Airplanes traveling in the opposite direction would need to resist this force, and they simply dont - because the earth and air are not moving.

(Air density is the mass per unit volume of Earth's atmosphere. Air density, like air pressure, decreases with increasing altitude. It also changes with variation in temperature or humidity. At sea level and at 15 °C air has a density of approximately 1.225 kg/m3 (0.001225 g/cm3, 0.0023769 slug/ft3, 0.0765 lbm/ft3) according to ISA (International Standard Atmosphere).

you are defaulting back to a point that I have already shown to be incorrect
as for your arbitrary copy/paste of air density info, ok? and?
