Possible or not?

One of my friends recently sent me this video of stunt pilot James Andersson in a Red Bull Air Race and asked me if this was possible or not. Given some of my ground school and understanding, I wrote him back with the following explanation: "Because this plane is a certified stunt plane, the engine has enough thrust to provide vertical lift, in which case the wings aren't needed for vertical flight (in fact no matter how fast an airplane is flying, if the relative angle of attack (wing to wind) exceeds a certain angle the plane stalls unless the engine has enough thrust for vertical lift. This is completely possible and as I watched the wing come off it is exactly what I thought the pilot should have done. Now whether or not the video itself is real, looks real enough to me." I wonder what do others have to say about this video. Do you think its possible or not? Please post your comments.
