Wheelchair Double Backflip!

You may recall Aaron "Wheelz" Fotheringham from a couple weeks ago when he did a backflip in his wheelchair at some kind of extreme stunt event thing-- which was purported to be the first backflip ever successfully landed on a wheelchair.

Well, now Wheelz has done himself one better: Whoa! Double backflip, all the way across the sky. What does this mean?!?
