[Aerkuld]

I saw an aerobatic plane similar to that doing some incredible moves (albeit with both wings) at the Chino airshow a few years ago. If I hadn't seen it with my own eyes I wouldn't have thought it possible. He would do a VERY slow pass low and level. In the middle of the pass he would flip the plane nose up 90 degrees seemingly on the spot so the maneuver was done faster than the plane was flying (if that makes any sense?). It looked as though the plane should have just stalled out as it was then travelling almost horizontally but bottom first. He would then just power it up vertical. The only way I could think that this could be done was by blowing lots of air over the control surfaces using the prop and then directing the air with the control surfaces almost like vectored thrust. It just looked physically impossible.

Looking at the video I wouldn't have thought it was a very high G maneuver when the wing 'fell' off. I suspect it might be fiddled with but I would also think that it might be possible with a lot of skill and a lot more luck.
