You know eye candy is what people like to see. In basketball, the dunks are what people want to see. Why? Not because you get more points, but because it is spectacular. Seeing acrobatic and 3D plane has the same draw. The spectator doesn't care about the skill it takes to land without a bounce, but the eye candy of acrobatics. It is just a simple fact of life, not meant as a shot toward anyone or their flying preference.
