Blue, I did read all of your post (2nd from the top on p37), and it's flawed.

Without responding to all of your 2piR references, the major flaw is you (and other CF'ers) fail to see that motion through air and motion over ground are two different things. Do you understand that you can have motion over ground without motion through air (i.e. tailwind)? Do you understand that you can have motion through air without motion over ground (headwind)?

Answer those two questions for me.
