I've landed countless times missing most of a wing. It's not that hard to do, but you need to know the plane you are flying. Some are much easier than others.
The trick is to get the plane slow enough so you can get your flaps out, assuming you still have both of them but keep it fast enough it doesn't stall b4 you get the flaps out. Once you get the flaps out it's almost a walk in the park landing.
I had one almost amazing landing in a P38J. I was at 10-12k engaged with a con. He knocked half my wing off while I was already in a dive and going very fast. I lost control of the plane and fought it all the way to the deck and recovered slightly before hitting the water.
The area was full of cons so I couldn't take the time to slow it down to use flaps. I managed to get it slow enough to get my gears out and touch down of the airfield for a criss cross landing across the field.
While I had landed p38's missing 1/2 wing b4 this one really made me happy because it was an extremely hard landing, because of how hard it had been to save the plane in the air. Well I got it on the ground doing about 150mph but somehow I couldn't miss the Bomber Hanger that I plowed into the side of.
Another time I managed to break off both wing tips on a 262. To my amazement it actually flew pretty good and IMO was a bit faster missing the wing tips. However it was a bit hard to land the thing.
I did managed to get a successful landing but it was pretty tough to get it slow enough to get flaps out and keep it from stalling prior to landing.
