"A G something" you ain't right. Lol! That is a sweet little point. I look at points like this and wander if natives actually understood aerodynamics or if it's common sense that has been over complicated by modern man. ??
Thanks man I think they had an understanding at a much more personal level than someone who knows how to write out a mathematical equation to solve a problem.
The way I see it it's closer to art at that point and probably uses a different part of the brain.. You sure are full of deep thoughts there dude... lol.
