Cool Trick: Side Aerial — Sideways

Most gymnasts in the US learn a side aerial on floor in their second or third year of competition, but the majority don't take it to beam until several years later -- if at all. The margin for error on beam is so small, that unless an athlete has a very square (hips in line) aerial, she won't be able to stay on.

So, imagine the margin for error if you moved that beam aerial sideways? Having trouble visualizing it? Here's British gymnast Rhian Pugh performing it in 2005. It's pretty amazing. The strange part is, I believe both skills are worth the same value in the Code of Points. I think the side-side aerial is much harder.
