While the fundamental premise is correct, the aircraft is flowing with the environment and it could care less, and the person on ground has vision cues that may be misleading, there is defineately something that happens to a plane when turning in wind.  There is that moment, or two, and I think its more pronounced with certain configurations, where the airplane flying status is vulnerable to stall and crash.  If you've ever flown a basic .40 trainer on a windy day, say 20-30mph wind, as you head into the wind and pull a loop, as you get on the top side and are inverted and heading downwind, the controls get sloppy and the plane may even flounder in the air until it starts flying again.  My favorite flying is in the wind, the more windy it is the more likely I'm gonna get to the field, put on dirt-bike goggles to block the dust,  and put something up.  My record is 40mph w/ 60mph gust w a .40 sport plane, have done almost that much w/ a .90 heli too, the only problem w/ the heli is trying to land w/ the rotor disc at a 45 degree angle to the ground... need to level it just as you cut the power and stick it to the ground.  Aside from theorems and laws there is a personal and significant thing happening at that moment.

Anyways, happy flying.[8D]
