A person can travel inside a moving plane because it is a closed environment - try walking on the outside of the plane and tell me how great your theory is.
The earth is not a closed environment in the helio model.
The plane is moving with the air in your example
just as the person is moving with the plane in his
closed/open systems have nothing to do with it (do you know what these are?)
the important concept here is relative velocity, which I have failed to see you address once.
