> Cessna aircraft have a hinge line on the upper surface. As a result, turning the aileron down causes a sharp angle on the upper surface. The air is unable to flow around such a sharp edge and stays attached. The result is a sudden right wing tip flow separation.
Should this say "The air is unable to flow around such a sharp edge and does not stay attached"?
I also caught this seeming error. It stood out especially since the rest of the article is so well written. I don't know anything about flying so I thought it was perhaps a lay misunderstanding on my part.
