How so? Do planes move through a different fluid than cars? Aerodynamic principles hold on both planes and road vehicles, and they are very often intertwined. Racing spoilers are inverted airplane wings, for example. To use own words, "I'm just being point blank about it cause I'm tired of people who put up fairy tales as fact. Sorry if that offends you."
That's as far as I'm going here.
