You can see what wing stall is all about if you go over to Van's Aircraft web and click on the RV-12 stall/spin testing video's half way down the page. They have the wing and fuselage tuffed so that you can see how a stall develops. Notice the angle of the horizon in the background as the pilot slows down the aircraft for an unaccelerated stall.

Those are really cool videos. The sails of sailboats usually have tufts on them to warn the skipper that his sail is in a stall. (slow sailing) These tufts are usually called "tell tails" and if they are not streaming straight back, the sail is over trimmed.
