Nope. I saw the curvature. (try climbing a tower on a clear day if you can't afford a plane ticket. you'll see.)
You made up some bullshit about what "my own model" is and says : - D
Every single navigator, planning long distance air or sea travel, has had to calculate the curvature of the earth. This has been going on for hundreds of years. The search for the Northwest Passage was motivated entirely by the fact that everyone knew the earth was round : - D
I have no idea what your position is, and I don't care. You cannot prove the earth is flat, so maybe just shut up? :-)
