I live in Southwest Oklahoma, and like the song says... The wind really does come sweeping down the plains!!! But anyway, we learn to fly in a lot of wind that grounds other pilots. We have to otherwise would would rarely fly.<div>
But to answer your question. In theory, as was said above. if the wind is blowing over the wing fast enough the plane will generate lift with no forward motion. it could just "pop" right up off the ground. Now to answer you question in practice. You mentioned flying in 40 mph winds. Unless you have lots of practice flying in wind you don't want to try and fly something like that. 40 mph steady and straight down the runway is predictable and you would probably be ok. But rarely does wind at that speed blow steadily. Rather, you will be dealing with a lot of gusts and "burbles" in the wind that is going to bounce the plane around as you try to land. And like I said, unless you're experienced in landing in that you'll more than likely go away from the ordeal with a broken plane.</div><div>
