TKD is actually varied depending on which body you compete under, but yes, you do learn a lot of aerial stuff. I never cared much for that kind of thing, but I liked the instructor/coach and I enjoyed fighting, I just kept my feet on the ground more often than some others. Once you are in the air you are commited to a certain movement, I never liked that idea personally. High kicking and all that has it's advantages at times though.
